[0063] The present application provides a method, system and related devices for AUX communication data processing, which are used to realize the collection and processing of standard AUX signals on an AUX link, and provide an efficient, reliable and low-cost AUX communication data processing solution.

[0064] It should be noted that the method for processing AUX communication data provided in this application is applied to an AUX communication data acquisition device, which is connected between the eDP host and the TCON IC when in use, and communicates with the eDP host and the TCONIC through the AUX interface to realize AUX data acquisition, storage, processing, output and other functions. The eDP host is an embedded display port host, which usually refers to a display interface controller integrated in a computing device (such as a laptop or a monitor), which is responsible for communicating with the display panel. The TCON IC is a timing controller chip, which is responsible for managing the pixel drive and timing control on the display panel and is the core component of the display panel.

[0065] See also Figure 1 , Figure 1 An embodiment of a method for processing AUX communication data provided by the present application includes:

[0066] 101. Collect standard AUX signals on the AUX link between the eDP host and the TCON IC;

[0067] The eDP host and TCON IC are in a master-slave relationship. The eDP host is the master device, responsible for initiating and controlling communication with the display, sending commands and controlling data transmission. The TCON IC is the slave device, responsible for responding to the eDP host's commands and performing corresponding operations, such as specific operations for displaying image data, managing the timing control of the display panel, etc. After the slave device TCON IC receives the command from the master device eDP host, it sends the response data through the AUX channel. The signal transmitted on the AUX channel is the standard AUX signal in this application.

[0068] In order to collect standard AUX signals, the AUX communication data acquisition device needs to be physically connected in parallel between the eDP host and the TCON IC. The parallel connection ensures that the AUX communication data acquisition device can serve as a monitoring end and can monitor the communication between the eDP host and the TCON IC without affecting their normal communication.

[0069] When the eDP host and TCON IC initiate a training action, the two exchange information through the AUX channel, and the AUX communication data acquisition device can actively intercept the standard AUX signal transmitted between the eDP host and the TCON IC. EDID and DPCD data are encapsulated and transmitted through the standard AUX signal, where EDID is the extended display identification data, which is the configuration information of the display device, including manufacturer, serial number, product type, screen size, resolution, etc. DPCD is DisplayPort configuration data, which is the configuration information of the DisplayPort device and is used to set and manage the DisplayPort link.

[0070] 102. Convert standard AUX signal into digital signal;

[0071] The standard AUX signal is transmitted through two differential lines (AUX_P and AUX_N), which has anti-interference ability and high signal integrity. Therefore, a differential signal receiver is needed to capture the differential signal between AUX_P and AUX_N, and amplify the differential signal through a differential amplifier to enhance the signal strength and improve the signal quality. The amplified analog signal is then input into the analog-to-digital converter ADC to convert the continuous analog signal into a discrete digital signal. The ADC samples the signal according to the preset sampling rate, converts the voltage value into the corresponding digital value, and realizes the conversion of the standard AUX signal into a digital signal.

[0072] 103. The digital signal collected by the previous clock and the digital signal collected by the current clock are stored in a buffer to obtain a sampling combination of two clock cycles;

[0073] 104. Decode the sampling combination in the buffer according to the Manchester encoding method in combination with the decoding flag to obtain a binary code;

[0074] The AUX channel of the eDP interface generally uses the standard Manchester encoding method. Therefore, in step 103 to step 104, the converted digital signal needs to be decoded according to the Manchester encoding method. Manchester encoding is a self-clocked encoding method. Each data bit changes level once in half a clock cycle. The decoding process needs to identify the level change in each clock cycle and convert it into the corresponding binary code. Please refer to Figure 2 , Figure 2 It is a standard Manchester coding waveform. The level from high to low represents logic 1, and the level from low to high represents 0.

[0075] In order to achieve accurate decoding, an FPGA decoding circuit combined with a buffer is designed in the AUX communication data acquisition device. Specifically, the FPFA decoding circuit of the standard Manchester code is designed to accurately extract the "10" and "01" signals from the Manchester code stream and convert them into "0" and "1" in ordinary binary code. For example, for Figure 2 The Manchester code "10011010010110", if you start decoding from the first bit, the binary code you get is "1011001", and if you start decoding from the second bit, the binary code you get is "110011" and two Manchester codes at the beginning and end.

[0076] According to the rules of Manchester encoding, any legal data bit must contain a level conversion. It can be seen that if there is only "1" or "0" in the Manchester code stream, the correct decoded data cannot be obtained. If "00" appears in the Manchester code stream, the code elements before and after "00" must be "1"; if "11" appears in the Manchester code stream, the code elements before and after "11" must be "0". Therefore, in this embodiment, the digital signal collected by the previous clock and the digital signal collected by the current clock can be saved in the buffer, and "00" and "11" can be used as the decoding flag of the wrong or invalid Manchester code. Combined with the decoding flag, the sampling combination in the buffer is decoded according to the Manchester encoding method to ensure the effectiveness of the decoding.

[0077] See also Figure 3 In the FPGA circuit of this embodiment, a buffer is designed, which is used to store the signal collected by the previous clock and the signal collected by the current clock to form a two-bit sampling combination. The Manchester code stream is the input digital signal. The digital selector is a key component for decoding. The digital selector can quickly output the corresponding decoded data bits according to the value of the sampling combination, and use the decoding flag to identify illegal sampling combinations, detect and indicate errors in the transmission process, and ensure the accuracy of the decoding process. The decoded data bits are output one by one to form a binary code that is decoded.

[0078] In some specific embodiments, when the sampling combination of the buffer is "10", "1" is output; when the sampling combination of the buffer is "01", "0" is output; when the sampling combination of the buffer is "00" or "11", it indicates that an error or invalid data occurs during data transmission, and at this time, the last valid decoding result is kept unchanged according to the decoding flag.

[0079] 105. Convert binary code into data stream and output the data stream in real time using a preset protocol format.

[0080] The AUX communication data acquisition device organizes the decoded binary code to form a continuous data stream, and encapsulates the data stream according to the preset protocol format, and outputs the encapsulated data stream to the host computer software or other target devices in real time.

[0081] In this embodiment, the AUX communication data acquisition device is connected in parallel between the eDP host and the TCON IC to realize the collection and processing of the standard AUX signal on the AUX link. The signal collection, decoding, data packaging and real-time output are realized through the AUX communication data acquisition device. It has high integration and provides an efficient, reliable and low-cost AUX communication data processing solution, which helps to improve the debugging efficiency of engineers and has a prospect of promotion and application.

[0082] The following is a detailed description of the AUX communication data processing method provided by this application. Figure 4 , Figure 4 An embodiment of a method for processing AUX communication data provided by the present application includes:

[0083] 401. Collecting a standard AUX signal on the AUX link between the eDP host and the TCON IC;

[0084] In this embodiment, step 401 is similar to step 101 in the aforementioned embodiment and will not be described again here.

[0085] 402. Isolate the DC component in the standard AUX signal by using a DC isolation capacitor to obtain an AC component of the standard AUX signal;

[0086] After collecting the standard AUX signal on the AUX link, the standard AUX signal needs to be converted into a signal that can be recognized by the FPGA device. In this embodiment, the signal processing is implemented by a DC isolation capacitor. Figure 5 , by connecting blocking capacitors C1 and C2 in series on the AUX_P and AUX_N links of the hardware AUX, the DC component is isolated, thereby retaining the AC signal component of the standard AUX signal. The blocking capacitor, also known as the coupling capacitor, can block the DC component and prevent the DC offset from affecting the subsequent circuit. The DC offset may cause the circuit's operating point to shift, thereby affecting the accurate transmission of the signal. After the standard AUX signal passes through the blocking capacitor, the resulting signal only contains the AC component. At this time, the AC component is further processed and converted into a signal that can be recognized by the FPGA device. In addition, the blocking capacitor can also prevent low-frequency interference signals from entering the subsequent circuit. These low-frequency interferences may affect the quality of the signal.

[0087] 403. Convert the AC component of the standard AUX signal into a digital signal;

[0088] Before converting the AC component of the standard AUX signal into a digital signal, the signal needs to be conditioned, including signal amplification, filtering, and level conversion, which are not limited here, to ensure that the signal meets the input requirements of the analog-to-digital converter ADC. After the signal conditioning is completed, the analog-to-digital converter ADC is used to convert the AC component of the standard AUX signal into a digital signal to meet the input requirements of the FPGA device. The FPGA device specifically collects the output of the digital signal through the differential pair IO.

[0089] 404. The digital signal collected by the previous clock and the digital signal collected by the current clock are stored in a buffer to obtain a sampling combination of two clock cycles.

[0090] 405. Decode the sampling combination in the buffer according to the Manchester encoding method in combination with the decoding flag to obtain a binary code;

[0091] In this embodiment, steps 404 to 405 are similar to steps 103 to 104 in the above embodiment, and are not described again here.

[0092] 406. Convert the binary code into a data stream according to bytes;

[0093] After completing Manchester decoding in FPGA, a string of binary codes is obtained. These binary codes need to be converted into data streams according to bytes for subsequent processing and transmission. Specifically, the binary codes are combined according to 8 bits (one byte) and converted into data streams.

[0094] 407. Packing and outputting the data stream according to a preset protocol format;

[0095] After the data stream is converted into byte combinations, it is necessary to package the data stream according to the preset protocol format to form a data packet that conforms to the preset protocol format, ensure the integrity and parseability of the data packet, and then output the packaged data packet to the host computer or other processing unit in real time.

[0096] The preset protocol format refers to the preset AUX request and response protocol, and the preset protocol format is specifically: synchronization header (SYNC) + synchronization end (SYNC END) + command (CMD) + data (DATA) + communication end (STOP). The synchronization header field and the synchronization end field are used to indicate the start of the data packet and the end of the synchronization phase to ensure that the receiving end can correctly parse the data packet; the command field is used to indicate the communication type and operation information of the data packet to ensure the correct parsing and processing of the data packet; the data field is the actual data content transmitted; and the communication end field is used to indicate the end of the data packet.

[0097] Among them, the command (COMM3:0) consists of 4 Manchester code bits. The highest bit 3 is used to indicate the communication type. The highest bit 3 is 1 for eDP communication, and the highest bit 3 is 0 for IIC communication. The remaining bits are used to indicate operation information. When in eDP communication, bits 2:0 is 000 for eDP write operation, and bits 2:0 is 001 for eDP read operation. When in IIC communication, bit 2 indicates the intermediate state. When it is 1, it means starting communication, and when it is 0, it means communication. Bits 1:0 is the IIC command. When it is 00, it means IIC write, when it is 01, it means IIC read, when it is 10, it means write status request, and 11 is reserved. The specific classification is as follows:

[0098] COMM3:0->1000->8->DPCD Write

[0099] COMM3:0->1001->9->DPCD Read

[0100] COMM3:0->0100 / 0000->4 / 0->AUX IIC Write

[0101] COMM3:0->0101 / 0001->5 / 1->AUX IIC Read

[0102] See also Figure 6 , Figure 6 The following is an FPGA waveform of a communication instruction between the eDP host and the TCON IC intercepted by the AUX communication data acquisition device. The instruction uses the 09 command to read back the 16-byte output of the 00 register of the DPCD, which is: 0x00 0x14 0x0f 0xc4 0x00 0x00 0x00 0x010xc0 0x02 0x01 0x00 0x00 0x00 0x010x00.

[0103] In some specific embodiments, since the number of captured commands is relatively large, in order to better distinguish each instruction, after the data stream is packaged according to the preset protocol format and a number of output instructions are obtained, a separator and a timestamp may be added to the front end of each output instruction, and the instructions may be output in real time. Specifically, 0xFF may be added to the front end of each output instruction as a separator, and a 4-byte timestamp may be added, in units of us.

[0104] 408. Transmit the data stream to the UI interface through the serial port for real-time display and interaction.

[0105] In this embodiment, the packaged data packet can be sent to the host computer through the serial port of the FPGA device at a baud rate of 1Mbps. On the host computer side, the received data packet is parsed according to the preset protocol format, the valid data therein is extracted, and the parsed data is displayed in real time on the UI interface to realize the dynamic display of data, which is low-cost and simple to operate. The printing and analysis of AUX communication data can be realized using general serial port software without specifying software. Furthermore, interactive functions such as data refresh, historical data query, data export, etc. can be provided on the UI interface, and the interactive operation between users and data can be realized through buttons and other controls.

[0106] In this embodiment, for the AUX level of different TCON ICs, the DC component of the signal is filtered out by a differential DC circuit, and the AC signal is retained. The FPGA device outputs and collects the IO through differential pairs, and then the FPGA decodes the collected signal according to the standard Manchester encoding method. Finally, the FPGA device prints the parsed data to the UI in real time through the serial port at a baud rate of 1Mbps to obtain the final interactive data. The AUX communication data acquisition device realizes efficient acquisition, accurate decoding and real-time transmission of signals on the AUX link, meeting the requirements of high data acquisition rate, fast test time, simplified test process and low cost. Compared with the existing AUX data monitoring instruments, it has higher integration, more complete functions, faster speed, higher compatibility and lower cost. It is currently compatible with and tested a variety of TCON ICs and display driver chips. In addition, the AUX communication data acquisition device can achieve continuous development and upgrading, and can customize the protocol according to the actual usage scenario, which has a prospect of promotion and application.
