Background technique

The video processing process in the traditional baseboard management control chip is that the video data on the server host end is transmitted to the VGA of the baseboard management control chip through PCIe, and then the original video data in RGB format is generated. Capture RGB raw data into the chip, convert the original RGB format video data into YUV format data through the color space conversion module (RGB2YUV), and then cache the Y, U, V data with the on-chip storage resources (FIFO ), according to the requirements of the post-stage JPEG compression format, and in accordance with the BLOCK format conversion sequence, to transfer the BLOCK data to the post-stage JPEG IP, 16 Y_FIFOs, 16 U_FIFOs, and 16 V_FIFOs are required. At the same time, according to the practical experience of the project, the maximum resolution (1920*1200), the depth of the FIFO is 16384, and the width is 8bits to satisfy the situation that the FIFO will not be full or lost. Then input it to the JPEG compression IP (supporting YUV444/YUV422/YUV420 compression format) in the order of BLOCK, write the data to DDR after the compression is completed, the EMAC (network card) driver reads the compressed data, and transmits the video data to Remote, for remote display.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

Based on the above purpose, the first aspect of the embodiments of the present invention proposes an embodiment of a method for debugging a video function in a baseboard management control chip. Figure 1 shows a schematic flowchart of the method.

As shown in Figure 1, the method may include the following steps:

S1 is to determine whether the video function of the baseboard management control chip is abnormal in response to the tape-out backtest of the baseboard management control chip. Chip tape-out is generally divided into MPW tape-out and mass-production tape-out. MPW tape-out is also called multi-project wafer tape-out. Multiple integrated circuit designs with the same process are placed on the same wafer for tape-out processing. Each design Varieties can get dozens of chip samples for experiments and verification tests in the product development stage. The cost of MPW tape-out is shared by all projects participating in MPW according to the chip area, and the actual cost is only 5%-10% of the original cost, which greatly reduces the cost and risk of the integrated circuit research and development stage. The application scenario of the present invention is for the test after MPW tape-out regression. During the test, if the video function of the substrate management control chip is abnormal, and it is impossible to locate which module is abnormal (design abnormality) or whether the abnormality occurs in the later In the process of terminal design, manufacturing and packaging, the present invention can be used to rule out whether the design is abnormal and the specific module where the abnormality occurs.

S2 In response to the abnormality of the video function of the baseboard management control chip, detect the function of each module in the baseboard management control chip. As shown in Figure 2, set up self-check sub-modules for each module in the baseboard management control chip. If the video function of the baseboard management control chip is found to be abnormal, the driver will issue register configuration to enable the video function SELF_CHECK (self-check) Function. That is, each self-test sub-module accepts the configuration of CFG_REGS to enable the self-test function of each sub-module.

S3 In response to the detection result of the module that the function of the module is abnormal, modify the code of the abnormal module. If the detection result of the module is normal, there is no need to deal with it. If the detection result of the module is abnormal, it is necessary to reorganize and modify the design code of the module until all the functions of the modules are normal.

By using the solution of the present invention, the speed of debugging the video function of the substrate management control chip can be greatly improved, the project cycle can be shortened, the process of starting mass-produced chips can be accelerated, and the success of mass-produced chips can be ensured.

In a preferred embodiment of the present invention, the detection module includes a data capture module, a color space conversion module, a BLOCK conversion module and a compressed data output module. The functions of each module in the baseboard management control chip are as follows. VGA writes the original RGB data of the host into the space specified by DDR (that is, Source_Data), and then DATA_CAP (data capture module) reads the RGB data from the DDR, and reads back the original RGB data. The data is input to the color space conversion module (Color_Conver) for color space conversion, converted into data in YUV format, and then the YUV data enters the BLOCK_Gen module, which generates data in BLOCK format according to the requirements of the subsequent JPEG IP, and completes YUV in the JPEG IP After the BLOCK data is compressed, it is written into the DDR through CMP_DATA_OUT (compressed data output module) for the driver to read. When the video function of the baseboard management control chip is abnormal, it is necessary to perform self-test on the above modules.

In a preferred embodiment of the present invention, in response to the abnormal video function of the baseboard management control chip, detecting the functions of each module in the baseboard management control chip includes:

At this time, the data source of the DATA_CAP module is switched from DDR to DATA_CAP_HW_CHECK. The DATA_CAP_HW_CHECK sub-module receives one or more frames of video data sent by the software or driver through the AHB_SLAVE interface (in order to speed up the processing speed, a smaller resolution can be used, such as 640*480), and temporarily stores the video data in RAM_A. The AXI_MASTER interface accesses the AXI_SLAVE interface of the DATA_CAP_HW_CHECK submodule (in the normal processing flow, the DATA_CAP module accesses the DDR through the AXI_MASTER interface) to obtain one or more frames of video data, which are processed by the DATA_CAP module (the processing flow is consistent with the normal processing flow) , and then output to the DATA_CAP_HW_CHECK submodule through the INTF interface. It is worth noting that this INTF interface is an interface with the output to RGB2YUV in the normal process, that is, to ensure the interface of the DATA_CAP module and the internal operation mechanism and functions and the normal processing of video data is consistent. After the DATA_CAP_HW_CHECK sub-module receives the video data, it is temporarily stored in RAM_B for driver or software to read. The software or driver verifies the read-back data. It is worth noting that the DATA_CAP module completes the data capture and does not modify the data, so it only needs to verify the read-back data and the original data sent to RAM_A That's it. If the verification results are consistent, it is determined that the function of the DATA_CAP module is normal. If the verification results are inconsistent, it is judged that the function of the DATA_CAP module is abnormal, and the design code needs to be reorganized and modified.

The Color_Conver_HW_CHECK sub-module receives one or more lines of video data delivered by the software or driver through the AHB_SLAVE interface (in order to speed up the processing, a smaller resolution can be used, such as a few lines of 640*480 data), and temporarily stores the issued line data to RAM_A, and send it to the Color_Conver module for processing through the INTF_A interface (in the normal processing flow, the Color_Conver module receives the video data of the DATA_CAP module through the INTF_A interface), after being processed by the Color_Conver module (the processing flow is consistent with the normal processing flow), Then output to the Color_Conver _HW_CHECK submodule through the INTF_B interface. It is worth noting that this INTF_B interface is the same interface as the output to the subsequent BLOCK_Gen module in the normal process, that is, to ensure the interface of the Color_Conver module and the internal operation mechanism and functions and video data The normal processing of is consistent. The Color_Conver_HW_CHECK sub-module receives the converted data through the INTF_B interface and temporarily stores it in RAM_B for driver or software to read and verify. If the verification results are consistent, it is judged that the function of the Color_Conver module is normal. If the verification results are inconsistent, it is judged that the function of the Color_Conver module is abnormal, and the design code needs to be reorganized and modified.

As shown in Figure 5, when performing SELF_CHECK on the self-developed module BLOCK_GEN, the BLOCK_GEN_HW_CHECK submodule receives the configuration of CFG_REGS to enable the SELF_CHECK of the BLOCK_GEN module. At this time, the data source of the BLOCK_GEN module is switched from the Color_Conver module to the BLOCK_GEN_HW_CHECK submodule. The BLOCK_GEN_HW_CHECK sub-module receives 16-line or 32-line video data sent by software or drivers through the AHB_SLAVE interface (because BLOCK conversion is based on 16-line units, in order to speed up the processing, a smaller resolution can be used, such as 16 lines of 640*480 or 32 lines of data), temporarily store the issued line data in RAM_A, and send it to the BLOCK_GEN module for processing through the INTF_C interface (in the normal processing flow, the BLOCK_GEN module receives the video data of the Color_Conver module through the INTF_C interface), after After the processing of the BLOCK_GEN module (the processing flow is consistent with the normal processing flow), it is output to the BLOCK_GEN_HW_CHECK sub-module through the INTF_D interface.
