Embodiment
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
Serial communication protocol has multiple mode according to classification: asynchronous start-stop type agreement, BISYNC, bit-oriented synchronous protocol etc., but their processing logic flow process has common point (its transfer process is as shown in Figure 2).
In the start-stop type asynchronous protocol, the transmission of data is a character, a character transmission, begins with start bit, finishes with position of rest, does not have the regular time space requirement between the character.All there is a start bit (low level front of each character, logical value 0), character itself is made up of 5～7 bit data positions, then the character back is a bit check position (also can not having check bit), last the position or one and half or two be position of rest, the position of rest back is the spare bits of indefinite length.
In synchronous protocol, not only to transmit a character, but stipulated character that they also are the Control on Communication word as the beginning of institute's data block transmitted and the control information of end mark and whole transmission course based on character transmission.Wherein, SYN is sync character (Synchronous Character).SOH is a preface beginning character (Start Of Header).STX literary composition beginning character (Start Of Text).The data block back is whole character of group (End OfTransmission Block is called for short ETB) or end-of-text character (End Of Text is called for short ETX).One frame be check code at last.
Characteristics based on the bit synchronous transmission are that frame data that transmitted can be any positions.It is made up of opening flag character 01111110, field, address, controlling filed, information field, frame check information, cyclic redundancy check (CRC) code (CRC).
In fact, can realize supporting different agreements by controller is configured.Maximum between the different agreements is not both the control signal difference in the host-host protocol.The different operation in transmission course has been represented in different values, different combinations.
Fig. 3 is the block diagram according to the serial interface controller of the support multiple transport protocols of first embodiment of the invention.As shown in Figure 3, this serial interface controller comprises:
One, protocol configuration unit.The protocol type dispensing unit can be configuration host-host protocols such as UART, SPI, IIC, SSP, I2S, SSI (synchronous serial interface), MICROWIRE.
Two, agreement general purpose register set.The agreement general purpose register set comprises clock sampling mode register (rising edge, negative edge), clock frequency enable register (clock frequency, the method for synchronization), status word register, startup command control register etc.
For example, clock control logic produces correct time clock according to the clock frequency register, is ns such as the unit that can arrange the clock frequency register, if register value is 1000 so, represents the 1MHz clock frequency.
For example, if method of synchronization register is 1 expression synchronous transmission, then meaning has clock to export to external unit, and the Clk in the output signal will use, and at this moment interface control unit will be controlled.Interface control unit can output to Clk to the clock that clock control logic produces.If method of synchronization register is 0 expression asynchronous transmission, then without the Clk signal.
Order control register group comprises command format register, start bit number register, data bits register, position of rest number register etc.Such as, the data bits register, the value of position of rest number register IIC can be made as 8, and UART can dispose, and the value of position of rest number register can be 4, and this may be that numeric ratio is bigger in the agreement of supporting.
Status register in the control word register is represented current transmission state.For example, IIC can be state such as idle, as to start, transmit, stop.
Startup command control register part is an example with IIC, is clock line when being high, and data line is from high step-down, and expression starts, and the startup command register can represent that front two is represented first state of two signals, back two bit representation NextStates with 4 so.Such as, value 1110 promptly can be represented startup command.Startup command logic in the interface control unit produces suitable clock signal just according to the value of arranging in the register.For the various protocols that needs are supported, the figure place of register is determined according to actual conditions.Such as with 6 situation, front three is represented first state, back three bit representations, second state, and the agreement that has is with 1,2,1,3 of the usefulness that has.The agreement that also has is not only seen the one the second states, may require continuous four high level in a certain position.This register just needs the 3*4=12 position long so.So the size of a certain register and definition will be according to the application decisions of circuit.
Three, special register.With the UART agreement is example.Because UART requires to support string and conversion, so parallel figure place register should be arranged.If figure place is 64 or 32, and the first in first out buffer area (FIFO) in the design not necessarily just is 64 or 32, then needs transmission mode register (its can use byte, word (16), double word (32) to wait to describe need how to make up become at last parallel).
Because UART is asynchronous, not exporting clock, must be impulse speed but require data transmission, and the value of this pulse clock is some fixing values, such as 115200,9600 etc., so the effect of clock frequency enable register promptly is to determine whether the value of clock frequency register is effective.If the value that is provided with is not these optional values, that just is made as 0.Therefore, the UART agreement needs specified register, can be called the data pulse register.
Four, interface signal control module.The interface signal control module comprises the logical process of some protocol characteristics, process is at first defining the protocol characteristic needs processing of which big class according to protocol type, then at various piece, produce protocol compliant and meet sequential relationship between the signal that general and special register is provided with.
Verification mode partly is to be very or even parity check according to general verification mode register, and this should be consistent with peripheral hardware.If for even parity check, in the end the number of a benefit just gather even number each 1.Certain general verification mode register also can be set to not verification, and this part processing logic is just simple relatively, and directly transmission just can.
In addition, serial interface controller as shown in Figure 3 can also comprise the internal bus interface unit.This part comprises metadata cache, is exactly FIFO.So fifo controller is arranged, then serial-parallel conversion circuit will be arranged.
