It should be understood that data so used may be interchanged under appropriate circumstances, eg, can be implemented according to an order other than those presented in the illustrations or descriptions of the embodiments of the present application.

Furthermore, the terms "comprising" and "having" and any variations thereof, are intended to cover but not exclusively include, for example, a product or device incorporating a series of components is not necessarily limited to those explicitly listed, but may include No other components are expressly listed or inherent to these products or devices.

The term "module" as used in this application refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic or combination of hardware or/and software code capable of performing the function associated with that element.

Currently, pins of a Bluetooth baseband integrated circuit (such as an integrated circuit of a Bluetooth controller) can output a data reception status signal rx_data, a data transmission status signal tx_data, and a radio frequency control signal. Among them, in the integrated circuit, the general-purpose input/output interface GPIO is used to output various signals. GIO (abbreviation of General Input/Output Ports) is more powerful than GPIO, and can precisely control which microsecond to pull the pulse signal high, and which microsecond to pull the pulse signal. The pulse signal is pulled low in seconds, and the GIO is used to output the radio frequency control signal.

FIG. 1 exemplarily shows a signal waveform diagram of a pin output of a Bluetooth baseband integrated circuit. As shown in Figure 1, the data receiving state signal rx_data, the data sending state signal tx_data, and the radio frequency control signal (also called GIO state signal) output by the pins of the integrated circuit are composed of a high level 1 and a low level 0. Wave signal, according to the above three signals, it is convenient to know whether the Bluetooth baseband integrated circuit is sending and receiving data. For example, when the data reception status signal rx_data is high level 1, it means that the Bluetooth baseband integrated circuit has received a data packet; the data transmission status signal tx_data When it is a high level of 1, it means that the Bluetooth baseband integrated circuit has sent a data packet. When the GIO status signal is a high level of 1, it means that the radio frequency module in the Bluetooth baseband integrated circuit is working.

It should be noted that FIG. 1 is only an example, the data receiving state signal rx_data, the data sending state signal tx_data, and the GIO state signal may also be signals of other waveforms, such as sine signal, cosine signal, triangular wave signal, etc. However, according to the data receiving state signal rx_data, the data sending state signal tx_data, and the GIO state signal output in FIG. 1 , the execution position of the program cannot be determined.

The Bluetooth baseband integrated circuit only provides the function of data transmission and reception. As for which physical channel and which method to send and receive data at which time, it is controlled by the program of the Bluetooth baseband integrated circuit. The Bluetooth baseband module, Bluetooth radio frequency module, Bluetooth modem and other circuit modules The coordination work is also controlled by the program. Errors in program operation may cause errors in the time when the Bluetooth baseband integrated circuits send and receive data, and ultimately fail to work. Therefore, it is necessary to determine where the program runs.

A current solution is to determine the running position of the program through the printing information output by the application console. Generally, for the debugging of programs with low real-time requirements or no real-time requirements, some simple printing information tracking programs can be added. operating position. However, devices such as Bluetooth controllers have high requirements on the real-time performance of the program. Due to the slow speed of printing information, and a large amount of printing information will take a long time, the program cannot be specified in the specified time due to adding more printing information. After the operation is completed within the time, the data sending and receiving time of the Bluetooth baseband integrated circuit is finally caused to be wrong. On the other hand, printing information is only used to indicate the execution of the code in the program, not the length of time the program has been run.

To solve the above problems, embodiments of the present application provide a program debugging method and apparatus. In some embodiments of the present application, the first debug signal dbg_clk and the second debug signal dbg_data are output by using two GPIOs of the Bluetooth baseband integrated circuit to indicate the start position and end position of the program, and the data reception status signal rx_data, data transmission The status signal tx_data and GIO status signal are similar. Connect the signal lines of the first debugging signal dbg_clk and the second debugging signal dbg_data to the logic analyzer, and analyze the waveforms of the first debugging signal dbg_clk and the second debugging signal dbg_data to determine the program. The running time length of the program can be debugged according to the running time length of the program, so that the Bluetooth controller can accurately control the sending and receiving state of the data.

FIG. 2 exemplarily outputs a flowchart of a program debugging method provided by an embodiment of the present application. As shown in Figure 2, the method can be executed by software or by a combination of software and hardware, and mainly includes the following steps:

S201: Acquire a first debugging signal and a second debugging signal.

In this step, the first debug signal dbg_clk and the second debug signal dbg_data are used to indicate the start position and end position of the program, and the start position and end position of the program can be determined according to the first debug signal and the second debug signal. Specifically, the number of pulse signals in the pulse signal sequence at the first position in the first debugging signal is obtained, and the level value corresponding to each pulse signal in the pulse signal sequence at the first position in the second debugging signal is obtained; if the first position The number of pulse signals in the pulse sequence and the level value corresponding to each pulse signal in the pulse signal sequence at the first position match the number and level value of the pulse signal corresponding to the starting position set by the specific program, then determine The first position is the starting position of the program; if the number of pulse signals in the pulse sequence at the first position and the level value corresponding to each pulse signal in the pulse signal sequence at the first position, correspond to the end position set by the specific program. If the number of pulse signals and the level value match, the first position is determined as the end position of the program.

The number of pulse signals at the first position may be the number of rising edges, the number of falling edges or the width of high-level pulse signals in the pulse signal sequence at the first position in the first debugging signal; The level value corresponding to each pulse signal in the pulse signal sequence of the position may be the rising edge, falling edge of the pulse signal on the first debugging signal or the level value corresponding to the pulse signal on the second debugging signal within the width of the high-level pulse signal.

S202: Determine the running time length of the program according to the start position and the end position of the program indicated by the first debugging signal and the second debugging signal.

In this step, the time corresponding to the start position is subtracted from the time corresponding to the end position to obtain the running time length of the program.

S203: Debug the program according to the running time length of the program.

In some embodiments of the present application, the first debug signal and the second debug signal are also used to indicate the embedded program during the running of the program, according to the pulse signal sequence of the first debug signal included between the start position and the end position of the program , the embedded program during the running of the program can be determined according to the first debug signal and the second debug signal.

During specific implementation, after the start position and end position of the program are determined according to the first debug signal and the second debug signal, the number of pulse signals in the pulse signal sequence of the first debug signal between the start position and the end position of the program can be obtained and the level value corresponding to each pulse signal in the pulse signal sequence of the second debug signal; determine the number of pulse signals in the pulse signal sequence of the first debug signal and the pulse signal sequence of the second debug signal between the start position and the end position Whether the level value corresponding to each pulse signal matches the number of pulse signals corresponding to the set embedded program and the level value of the pulse signal, if so, it is determined that the embedded program has been run during the program running.

In the above-mentioned embodiments of the present application, by determining the embedded program executed during the running of the program, it is possible to further understand the running status of the program, so as to further understand the status of the data sent and received by the Bluetooth baseband integrated circuit.

In some embodiments of the present application, the first debug signal and the second debug signal are also used to indicate the embedded program during the running of the program, according to the pulse signal sequence of the first debug signal included between the start position and the end position of the program, Then, the embedded program during the running of the program can be determined according to the first debug signal and the second debug signal.

During specific implementation, after the start position and end position of the program are determined according to the first debug signal and the second debug signal, the number of pulse signals in the pulse signal sequence of the first debug signal between the start position and the end position of the program can be obtained and the level value corresponding to each pulse signal in the pulse signal sequence of the second debug signal; determine the number of pulse signals in the pulse signal sequence of the first debug signal and the pulse signal sequence of the second debug signal between the start position and the end position Whether the level value corresponding to each pulse signal matches the number of pulse signals corresponding to the set embedded program and the level value of the pulse signal, if so, it is determined that the embedded program is run during the program running, as shown in Figure 3d .

In the above-mentioned embodiments of the present application, by determining the embedded program executed during the running of the program, it is possible to further understand the running status of the program, so as to further understand the status of the data sent and received by the Bluetooth baseband integrated circuit.

In some embodiments of the present application, the type of the program that cannot be determined according to the characteristics of the Bluetooth baseband integrated circuit can also be determined according to the first debugging signal and the second debugging signal.

In specific implementation, after determining the start position and end position of the program according to the first debug signal and the second debug signal, determine the first position between the start position and the end position of the program indicated by the first debug signal and the second debug signal. Whether the debug signal also includes a pulse signal sequence, if included, obtain the number of pulse signals in the pulse signal sequence of the first debug signal between the start position and the end position, and the second debug signal between the start position and the end position The level value corresponding to each pulse signal in the pulse signal sequence of the first debug signal; determine the number of pulse signals in the pulse signal sequence of the first debug signal between the start position and the end position and the corresponding pulse signals in the pulse signal sequence of the second debug signal. Whether the level value of the timer program matches the number of pulse signals and the level value of the pulse signal in the set timer program, if so, the program is determined to be a timer program, as shown in Figure 3c.

In the above embodiments of the present application, according to the pulse signal sequence between the start position and the end position of the program indicated by the first debugging signal and the second debugging signal, the type of the program that cannot be determined based on the characteristics of the Bluetooth baseband integrated circuit can be solved, In order to further understand the status of the bluetooth baseband integrated circuit sending and receiving data.

The program debugging method provided by the embodiment of the present application is described in detail below by taking an interrupt program as an example. It should be noted that the program debugging method provided by the embodiments of the present application may be applicable to interrupt programs with high timing requirements, and also applicable to the debugging of other programs.

In some embodiments of the present application, the first debug signal dbg_clk and the second debug signal dbg_data are set to respectively define waveform characteristics used to represent the start position and end position of the interrupt program. When the interrupt program starts to execute, the first debug signal The waveforms of dbg_clk and the second debug signal dbg_data have changed, and the waveform characteristics are the same as the waveform characteristics of the pre-defined start position of the interrupt program. When the execution of the interrupt program ends, the waveforms of the first debug signal dbg_clk and the second debug signal dbg_data changes, and the waveform characteristics are the same as those at the end of the predefined interrupt routine. The first debug signal dbg_clk and the second debug signal dbg_data are respectively output by two GPIOs of the Bluetooth baseband integrated circuit. In this way, by detecting the first debug signal dbg_clk and the second debug signal dbg_data output by the Bluetooth baseband integrated circuit, these two signals are Extract and analyze the waveform features of the interrupt program to determine the start position and end position of the interrupt program.

Wherein, the pulse width of the second debugging signal dbg_data can be set according to the pulse width of the first debugging signal dbg_clk, which specifically includes any of the following situations:

Case 1: The pulse width of the second debug signal dbg_data is equal to the number of rising edges of the first debug signal dbg_clk.

Case 2: The pulse width of the second debug signal dbg_data is equal to the number of falling edges of the first debug signal dbg_clk.

Case 3: The pulse width of the second debugging signal dbg_data is equal to the high-level pulse width of the first debugging signal dbg_clk.

It should be noted that the waveform feature used to characterize the start position of the interrupt program is different from the waveform feature used to characterize the end position of the interrupt program, so as to partition the start position and the end position of the interrupt program.

In some embodiments, the waveform characteristics used to characterize the start position and the end position of the interrupt program may include: at the start position and end position of the interrupt program, the first debug signal dbg_clk outputs a set number of pulses, and the second debug signal dbg_clk outputs a set number of pulses. The rising edge and/or falling edge of one or more pulses in which the debug signal dbg_data is set are in a set state (eg, a high-level state or a low-level state). That is, the number of pulses of the first debug signal dbg_clk and the level value of the second debug signal dbg_data at the rising or falling edge of the pulse of the first debug signal dbg_clk can be used to identify the start and end positions of the interrupt program. In specific implementation, the waveform characteristics representing the start position and end position of the interrupt program can be represented by coordinates (X, Y), where X represents the number of pulses of the first debug signal dbg_clk, and Y represents the pulse number of the second debug signal dbg_data at the set position. Level value, which can include any of the following:

Case 1: X is the number of rising edges of the first debugging signal dbg_clk, and Y is the level value of the second debugging signal dbg_data at the rising edge position of the first debugging signal dbg_clk.

Case 2: X is the number of falling edges of the first debugging signal dbg_clk, and Y is the level value of the second debugging signal dbg_data at the falling edge position of the first debugging signal dbg_clk.

Among them, the waveform feature used to characterize the start position of the interrupt program is different from the waveform feature used to characterize the end position of the interrupt program, and may specifically include the following situations:

Case 1: The number of pulses of the first debug signal dbg_clk is different at the start position and end position of the interrupt signal;

Case 2: At the start position and end position of the interrupt signal, the level value of the second debug signal dbg_data at the rising edge or the falling edge of the first debug signal dbg_clk is different;

Case 3: At the start position and end position of the interrupt signal, the number of pulses of the first debug signal dbg_clk is different from the level value of the second debug signal dbg_data at the rising or falling edge position of the first debug signal dbg_clk dbg_data.

In other embodiments, the pulse width of the first debug signal dbg_clk and the level value of the second debug signal dbg_data within the pulse width range can also be used to identify the start position and the end position of the interrupt program. During specific implementation, the waveform characteristics representing the start position and end position of the interrupt program can be represented by coordinates (X, Y), where X represents the pulse width of the first debug signal dbg_clk, and Y represents the second debug signal dbg_data in the first debug signal dbg_clk. level value within the pulse width range. Details are as follows:

Case 3: X is the high-level pulse width of the first debugging signal dbg_clk, and Y is the level value of the second debugging signal dbg_data within the high-level pulse width of the first debugging signal dbg_clk.

It should be noted that the pulse width of the first debug signal dbg_clk can be represented by bits.

In some embodiments of the present application, according to the characteristics of the integrated circuit, the type of the specific interrupt program in the Bluetooth baseband integrated circuit can be based on the data reception status signal rx_data, the data transmission status signal tx_data, the GIO status signal output by the pins of the Bluetooth baseband integrated circuit Determine, for example, the location where tx_data ends is a packet assembler (PacketAssembler, PKA) interrupt, the location where rx_data begins with data is a synchronization (synchronization, referred to as SYNC) interrupt, and the location where rx_data completes data reception is the packet disassembler (Packet assembler) Disassambler, PKD) interrupt, rx_data does not receive data and the position where the GIO status signal ends is no packet received (NO_PKT_RCVD) interrupt.

Taking the determination of the values of X and Y through Case 3 as an example, FIG. 3 a to FIG. 3 c exemplarily show waveform diagrams of the starting position and the ending position of the interrupt program provided by the embodiment of the present application.

Fig. 3a is a waveform diagram of the starting position and the interrupt position of the PKA interrupt program provided by the embodiment of the application. As shown in Fig. 3a, tx_data has high-level bits, and all the bits of rx_data are low-level, indicating that Bluetooth The baseband integrated circuit is sending data. According to the characteristics of the integrated circuit, the PKA interrupt program will be executed at the position where tx_data ends. It can be expected that the arrow is the position where tx_data ends. The dotted position after the arrow is the start position and end of the PKA interrupt program. Location. Among them, one bit of dbg_clk at the starting position is high level, X is recorded as 1, the high level of dbg_data corresponding to the high level bit of dbg_clk, Y is recorded as 1, and the starting position can be expressed as (1,1 ); at the end position dbg_clk has a high level, X is recorded as 1, the dbg_clk high level bit corresponds to the low level of dbg_data, Y is recorded as 0, and the end position can be expressed as (1,0).

Figure 3b is a waveform diagram of the starting position and the interrupt position of the NO_PKT_RCVD interrupt program provided by the embodiment of the application. As shown in Figure 3b, the bits of tx_data are all low levels, indicating that the Bluetooth baseband integrated circuit does not send data, and the rx_data The bits are all low, but the GIO status signal is pulled high, indicating that the radio frequency module of the Bluetooth baseband integrated circuit is working, and the current Bluetooth baseband integrated circuit is in the state of receiving data, but no data is received. According to the characteristics of the integrated circuit, the NO_PKT_RCVD interrupt is executed at the position where the GIO status signal is pulled from a high level to a low level (marked by the arrow), and the dotted position after the arrow is the start position and end position of the NO_PKT_RCVD interrupt program. . Among them, one bit of dbg_clk at the starting position is high level, X is recorded as 1, the high level of dbg_data corresponding to the high level bit of dbg_clk, Y is recorded as 1, and the starting position can be expressed as (1,1 ); at the end position dbg_clk has a high level, X is recorded as 1, the dbg_clk high level bit corresponds to the low level of dbg_data, Y is recorded as 0, and the end position can be expressed as (1,0).

It is worth noting that the timer interrupt program cannot be determined according to the data reception status signal rx_data, the data transmission status signal tx_data, and the GIO status signal output by the Bluetooth baseband integrated circuit. In some embodiments of the present application, in addition to determining the start position and end position of the interrupt program according to the first debug signal dbg_clk and the second debug signal dbg_data, the interrupt program can also be determined according to the first debug signal dbg_clk and the second debug signal dbg_data. The pulse signal sequence of the first debug signal between the start position and the end position determines the timer interrupt program.

FIG. 3c is a waveform diagram of a start position and an interrupt position of a timer interrupt program provided by an embodiment of the present application. As shown in Figure 3c, the bits of rx_data are all low levels, the bits of tx_data are high levels, and when the GIO status signal is pulled high, dbg_clk and dbg_data are high levels. At the position A indicated by the dotted circle, one bit of dbg_clk is high, X is recorded as 1, the high level of dbg_clk corresponding to the high level bit of dbg_data is high, Y is recorded as 1, and the A position can be expressed as (1 ,1); At the B position of the dotted circle, two bits of dbg_clk are high, X is recorded as 2, the first high level in dbg_clk corresponds to the high level of dbg_data 1, the second high level The high level of the corresponding dbg_data is 1, Y is marked as "01", and the B position can be represented as (2, 1); at the C position of the dotted circle, dbg_clk has a high level, and X is marked as 1 , the low level of dbg_data corresponding to the high level bit of dbg_clk, Y is marked as 0, and the C position can be represented as (1,0). Due to the small number of bits occupied by the A position and the C position, it takes less time to run the timer interrupt program. Therefore, the A position is used as the starting position of the timer interrupt program, and the C position is used as the end position of the timer interrupt program. Location can be used to indicate where the interrupt function ends in a timer interrupt routine.

It is worth noting that, at the same position, when multiple bits of dbg_clk are high, the order of the level value of dbg_data corresponding to each high-level bit can be from low-bit to high-bit, such as the B position. The Y in the middle is recorded as "01", and it can also be from the high bit to the low bit, for example, the Y in the B position is recorded as "10".

In order to track the running positions of more programs, more coordinates can be obtained according to the position of the embedded program during the running of the interrupt program indicated by the first debug signal and the second debug signal. Among them, the position coordinates of different types of embedded programs are different. The position marked by the coordinates (X, Y) in the interrupt program is unique. For example, in the NO_PKT_RCVD interrupt program (1,1) represents the starting position, then (1,1) cannot be used to represent the position of other embedded programs in the NO_PKT_RCVD interrupt program.

FIG. 3d is a waveform diagram of executing the embedded program between the start position and the interrupt position of the NO_PKT_RCVD interrupt program provided by the embodiment of the present application. As shown in Figure 3d, taking the NO_PKT_RCVDD interrupt program as an example, the data reception status signal rx_data, data transmission status signal tx_data and GIO status signal are consistent with Figure 3c. Between the positions, the first debug signal dbg_clk has high power, such as the position circled by the dotted circle, indicating that the embedded program is executed during the execution of the NO_PKT_RCVD interrupt program. As shown in Figure 3d, dbg_clk has three bits high. X is recorded as 3, the first high level in dbg_clk corresponds to the low level of dbg_data, the second high level corresponds to the high level of dbg_data, and the third high level corresponds to the low level of dbg_data 0, Y is denoted as "010", and the position of the embedded program can be represented as (3, 2), which is used to indicate that the embedded program to reduce the priority of the ACL link is executed during the NO_PKT_RCVD interrupt program running.

Based on the manner in which the first debug signal dbg_clk and the second debug signal dbg_data indicate the start position and end position of the interrupt program, the embodiments of the present application provide a method and apparatus for determining a data transmission and reception state.

FIG. 4 is an exemplary source flow chart of the method for debugging an interrupt program provided by an embodiment of the present application. The process mainly includes the following steps:

S401: Acquire a first debug signal and a second debug signal for indicating a start position and an end position of the interrupt program.

In this step, the start position and the end position of the interrupt program can be determined according to the first debug signal and the second debug signal. Refer to FIG. S202 for specific description, which will not be repeated here.

In S401, the level value of the second debug signal can be obtained at the rising edge or the falling edge of the pulse signal in the pulse signal sequence of the first debug signal at the first position, for example, in the timer interrupt program shown in FIG. 3c , at the A position (starting position), the pulse signal in the pulse signal sequence of the first debug signal has one rising edge, and the pulse signal in the pulse signal sequence of the second debug signal corresponding to the rising edge is obtained as high level 1 , obtain the coordinates of the first position (1,1); or, according to the width of the high-level pulse signal in the pulse signal sequence of the first debugging signal at the first position, obtain the second debugging signal corresponding to the high-level pulse signal The level value within the width of the high-level pulse signal at the position. For example, in the timer interrupt program shown in Figure 3c, at position A (starting position), the pulse signal in the pulse signal sequence of the first debug signal has 1 A high level of a bit width is obtained, the pulse signal in the pulse signal sequence of the second debugging signal corresponding to the high level bit is obtained as high level 1, and the coordinate (1, 1) of the first position is obtained.

S402: Determine the running time length of the interrupt program according to the start position and the end position of the interrupt program indicated by the first debug signal and the second debug signal.

In this step, the time corresponding to the start position is subtracted from the time corresponding to the end position to obtain the running time length of the interrupt program. Taking the timer interrupt program shown in Figure 3c as an example, the time A1 corresponding to the start position (1,1) is 3.507292426 seconds, and the time A2 corresponding to the end position (1,0) is 3.507301824 seconds. The run time length A was 9.398 microseconds (μs).

S403: Debug the interrupt program according to the running time length of the interrupt program.

In this step, since the interrupt program controls what data is sent by the Bluetooth baseband integrated circuit at what time, the running time lengths of different interrupt programs correspond to different data sending and receiving states, and the data sending and receiving states (such as data time of sending and receiving, data type, etc.). According to the data sending and receiving state specified in the communication protocol, the debugger can understand the operation of the interrupt program, which is convenient for debugging.

For example, taking the timer interrupt program shown in Figure 3c as an example, the running time of the timer interrupt program is 9.398 μs. The interrupt program is debugged according to the comparison result, so as to improve the time precision of the bluetooth baseband integrated circuit sending and receiving data.

In some embodiments of the present application, a specific type of program can be determined according to the characteristics of the data reception status signal, data transmission status signal and GIO status signal output by the integrated circuit. Taking the interrupt program as an example, for example, the position where tx_data ends is PKA Interrupt, the location where rx_data starts to have data is SYNC interrupt, the location where rx_data completes data reception is PKD interrupt, the location where rx_data does not receive data and the GIO status signal ends is NO_PKT_RCVD interrupt, see Figure 3a to Figure 3c for details. During specific implementation, the data receiving state signal, data sending state signal and video control signal output by the Bluetooth baseband integrated circuit are obtained, and the type of the program is determined according to the data receiving state signal, the data sending state signal and the GIO state signal; Run time length, determine the data sending and receiving state, and debug the program according to the data sending and receiving state.
