Referring to FIG. 3, it is a method flowchart of a data processing method provided by an embodiment of the present invention, and the specific description is as follows:

S101. Acquire data to be processed.

When a data sending command is received, the data sending command is parsed to obtain the data to be processed in the data sending command, and the data to be processed includes valid data to be sent to the receiving end.

It should be noted that, after the system starts to work, it keeps sending IDEL data before receiving the data sending command. Each bit of the IDEL data will be converted into a fixed code sequence. The fixed code sequence is "1100", and the IDEL data 4, each rising edge of IDEL data contains clock information, and each bit of IDEL data will be encoded as "1100", therefore, the encoding of IDEL data satisfies DC balance and contains clock information.

After the system receives the data sending command, it needs to send the received data. Before sending the data, it needs to encode the data to obtain the data packet corresponding to the data. After sending the data packet, the system The packet sending sequence is shown in Figure 5. The system receives the data sending command in the process of sending IDEL data, and the data packet obtained after encoding the data can be sent and then continue to send the IDEL data. It should be noted that Figure 5 The data packets shown in are the data packets obtained after encoding the data, and the process of encoding the data may refer to the process of S102 to S105.

S102. Add a preset packet header sequence to the front end of the data.

The packet header sequence (PREAMBLE) is used as the start identifier of valid data in the data, and the packet header sequence can be used to indicate the beginning of the data, wherein the valid data in the data includes but is not limited to device address, register address, read and write enable, ECC, The register value and CRC that need to be transmitted, among which, the data contains multiple data bits, the number of data bits of different valid data is different, and the data bits can be understood as bits.

S103: Determine the encoding type of each data bit in the data one by one, and convert the value in each data bit into an encoding sequence corresponding to its encoding type to obtain a packet encoding sequence of the data.

It should be noted that there are three encoding types, namely the first type, the second type and the third type, and different encoding types correspond to different encoding sequences.

When determining the encoding type, it can be determined according to the value and position information of the data bits.

S202. Obtain the numerical value and position information of the current data bit.

It should be noted that the value of each data bit in the data is a binary value, that is, the value of each data bit is either 1 or 0; the location information includes, but is not limited to, the sorting information of the current data bit in the data and the location in the data. The value of the previous data bit of the current data bit, wherein, if the data bit is the first data bit in the data, the value of the previous data bit of the current data bit in the position information of the data bit is empty.

Judging whether the numerical value of the current data bit is consistent with the numerical value of the previous data bit located in the current data bit;

If the numerical value of the current data bit is inconsistent with the numerical value of the previous data bit located in the current data bit, it is determined that the current data bit is flipped;

If the value of the current data bit is consistent with the value of the previous data bit located in the current data bit, it is determined that the current data bit does not flip.

It should be noted that the value of the data bit located before the current data bit can be determined from the position information of the current data bit.

It should be noted that when the value of the current data bit is different from the value of the previous data bit located in the current data bit, it can be determined that the current data bit has flipped, and there are two cases of flipping, one is that 0-1 occurs Flip, at this time, 0 is the value of the previous data bit located in the current data bit, and 1 is the value of the current data bit; another case is that a 1-0 flip occurs, at this time, 1 is located in the previous data bit. The value of the data bit, 0 is the value of the current data bit.

S205. Determine that the encoding type of the current data bit is the first type.

S206. Determine whether the value of the current data bit is 1; if it is determined that the value of the current data bit is 1, execute S207; if it is determined that the value of the current data bit is not 1, execute S208.

After the encoding type of the current data bit is determined, the value of the current data bit can be converted into an encoding sequence corresponding to its encoding type according to the encoding type of the current data bit, as follows:

When the encoding type of the current data bit is the first type, convert the value of the current data bit into a zero-polarity encoding sequence corresponding to the first type; when the encoding type of the current data bit is the second type, convert the current data bit The value of the current data bit is converted into a positive polarity coding sequence corresponding to the second type; when the coding type of the current data bit is the third type, the value of the current data bit is converted into a negative polarity coding sequence.

It should be noted that the above-mentioned method of converting the value of the current data bit into a coding sequence can be applied to all data bits in the data. Further, different coding types correspond to different coding sequences, wherein, when the coding type is the first type , the corresponding coding sequence is a zero polarity coding sequence; when the coding type is the second type, the corresponding coding sequence is a positive polarity coding sequence; when the coding type is the third type, the corresponding coding sequence is a negative polarity coding sequence.

It should be noted that the positive coding sequence, the negative coding sequence and the zero coding sequence are all composed of binary values, and the binary values in different types of coding sequences are different; exemplarily, the positive coding sequence is "1110", and the negative coding sequence The sequence is "1000" and the zero-pole coding sequence is "1100".

S104. Determine the coding polarity of each data bit based on the coding sequence of each data bit, and determine the sequence polarity of the packet coding sequence based on the coding polarity of each data bit.

In the method provided by the embodiment of the present invention, after the numerical value in the data bit is converted into a coding sequence, the coding polarity of the data bit can be determined according to the coding sequence, for example: when the coding sequence of the data bit is a zero-polar coding sequence , determine that the coding polarity of the data bit is zero polarity; when the coding sequence of the data bit is a positive polarity coding sequence, determine that the coding polarity of the data bit is positive polarity; when the coding sequence of the data bit is a negative polarity coding sequence, Determine the encoding polarity of the data bits to be negative.

In the method provided by the embodiment of the present invention, after the coding polarity of each data bit is determined, the sequence polarity of the packet coding sequence can be determined according to the coding polarity of each data bit; the sequence polarity of the packet coding sequence is determined to determine the sequence polarity of the packet coding sequence. Whether the packet coding sequence has reached DC balance, the sequence polarity is the same as the coding polarity, there are three types, one is positive polarity, one is negative polarity, and the other is zero polarity.

Referring to FIG. 7, it is a flowchart of a method for determining the sequence polarity of a packet coding sequence provided by an embodiment of the present invention, and the specific description is as follows:

S301. Determine a first number of data bits whose encoding polarity is positive, and determine a second number of data bits whose encoding polarity is negative.

Statistics are performed on the coding polarities of each data bit in the data, thereby determining a first number of data bits whose coding polarity is positive, and determining a second number of data bits whose coding polarity is negative, and further, also A third number of data bits with an encoding polarity of zero polarity may be determined.

The first quantity and the second quantity are compared to determine whether the first quantity is equal to the second quantity.

S303. Determine that the sequence polarity of the packet coding sequence is zero polarity.

When it is determined that the first number is equal to the second number, the number of data bits indicating that the encoding polarity is positive is equal to the number of data bits whose encoding polarity is negative, so it can be determined that the sequence polarity of the packet encoding sequence is Zero polarity also determines that the packet encoding sequence is DC balanced.

S304. Determine whether the first quantity is greater than the second quantity; if it is determined that the first quantity is greater than the second quantity, execute S305; if it is determined that the first quantity is not greater than the second quantity, execute S306.

When the first quantity is not equal to the second quantity, it is determined whether the first quantity is greater than the second quantity.

S305. Determine that the sequence polarity of the packet coding sequence is positive.

When the first number is greater than the second number, it indicates that the number of data bits whose coding polarity is positive is more than the number of data bits whose coding polarity is negative, so it can be determined that the sequence polarity of the packet coding sequence is positive At this time, the packet coding sequence has not reached the DC balance. At this time, the packet coding sequence needs to be supplemented with negative polarity coding, so that the packet coding sequence can reach the DC balance.

S306. Determine that the sequence polarity of the packet coding sequence is negative.

When the first number is not greater than the second number, that is, when the first number is determined to be less than the second number, the number of data bits indicating that the encoding polarity is negative is more than the number of data bits whose encoding polarity is positive. Therefore, it can be determined that the sequence polarity of the packet coding sequence is negative. At this time, the packet coding sequence has not reached the DC balance. At this time, the packet coding sequence needs to be supplemented with positive polarity codes to make the packet coding sequence reach DC balance.

In order to ensure that the packet coding sequence achieves DC balance, the present invention also supplements the packet coding sequence with a level balance sequence, wherein the level balance sequence is added according to the sequence polarity of the packet coding sequence, and the levels corresponding to different sequence polarities The content of the balance sequence is different. For example, when the sequence polarity is negative, the supplementary level balance sequence should be a positive code sequence, so the level balance sequence at this time can be specifically "1110"; When the sequence polarity is positive, the supplemented level balance sequence should be a negative code sequence, so the level balance sequence at this time can be specifically "1000", when the sequence polarity is zero polarity, the supplementary level balance sequence The level balance sequence should be a zero-polarity coding sequence, so the level balance sequence at this time can specifically be "1100".

The level balancing sequence is added at the end of the packet end sequence, whereby the packet coding sequence can be brought to zero polarity and the packet coding sequence can be DC balanced.

Referring to FIG. 10, it is an example diagram of encoding valid data in data provided by an embodiment of the present invention. As shown in the figure, the value of the first data bit of the data is 0, and the encoding type of the first data bit can be determined It is the third type. Therefore, "1000" can be obtained by encoding the first data bit as a numerical value. The values of the second data bit to the fourth data bit are all equal to the value of the first data bit. Therefore, you can It is determined that the encoding type of the second data bit to the fourth data bit is the first type, so the encoding of the second data bit to the fourth data bit is "1100", and the value of the fifth data bit occurs. Flip, and the flip method is "0-1", the value of the fifth data bit is 1, therefore, the encoding type of the fifth data bit is the second type, so the encoding of the fifth data bit is "1110" , the value of the sixth data bit and the seventh data bit are equal to the value of the fifth data bit, therefore, the encoding type of the sixth data bit and the seventh data bit are the first type, so the sixth data bit and the seventh data bit are of the first type. The codes of the first data bit and the seventh data bit are both "1100"; the value of the eighth data bit is flipped, and the flip method is "1-0", and the value of the eighth data bit is 0. Therefore, The encoding type of the eighth data bit is the third type, so the encoding of the eighth data bit is "1000".

Here is a further description of how the valid data of the data is encoded:

1. If the first bit data of the valid data of the data is 1, it is encoded as 1110; the first bit data is 0, then it is encoded as 1000;

2. When the data bit undergoes 0-1 conversion, the corresponding data bit code is 1110; when the data bit undergoes 1-0 conversion, the corresponding data bit code is 1000; when no data conversion occurs, the data bit code is 1100;

3. All DC imbalances are introduced by '1110' and '1000'. Each 0-1 transition will introduce a positive polarity (the number of 1s in '1110' is two more than 0's), and each 1-0 transition will introduce a negative polarity (the number of 1's in '1000' is more than 0's) two less). Because it is impossible to have two consecutive 0-1 inversions or 1-0 inversions, and 0-1 inversions and 1-0 inversions always occur alternately, therefore, at the end of data encoding, the difference between positive and negative polarities It can only be -1 ('1000' is one more than '1110', and the sequence polarity of the data packet coding sequence is negative), 0 (the number of '1110' and '1000' is the same, and the data packet coding sequence is the same at this time. The sequence polarity of the sequence is zero polarity), 1 ('1110' is one more than '1000', at this time the polarity of the data packet coding sequence is positive polarity), so add one at the end of the data packet coding sequence The corresponding dc_biase_bit (level balance sequence) is used to ensure that the polarity of the entire packet coding sequence is zero polarity; the specific method is that if the difference between the positive and negative poles is -1, then the sequence polarity of the packet coding sequence is negative. If the difference between the positive and negative poles is 0, then the sequence polarity of the packet coding sequence is zero, then the supplementary level balance sequence is “1100”. If the difference between the positive and negative poles is 1, and the sequence polarity of the packet coding sequence is positive, the supplementary level balance sequence is "1000".

It can be seen from the above that each data bit is encoded into a 4-bit encoding sequence, and the overall encoding efficiency is close to 1/4. Compared with the encoding method using the HDMI eARC protocol in the prior art, it has higher encoding efficiency. Besides, the present invention has the advantage that the adjacent duty ratio is closer to 1:1 in addition to the advantages of achieving DC balance and including clock information.

Further, when using the data processing method provided by the present invention to encode data, when the receiving end receives the corresponding data stream, it can use the decoding method corresponding to the data processing method provided by the present invention to perform decoding operations, thereby obtaining Valid data in the packet.
