Description

一种基板管理控制芯片调试方法、装置、设备及可读介质A substrate management control chip debugging method, device, equipment and readable medium

技术领域technical field

本发明涉及计算机领域,并且更具体地涉及一种基板管理控制芯片中视频功能调试的方法、装置、设备及可读介质。The present invention relates to the field of computers, and more specifically relates to a method, device, device and readable medium for debugging video functions in a substrate management control chip.

背景技术Background technique

传统的基板管理控制芯片中视频处理流程是服务器主机端的视频数据通过PCIe传递到基板管理控制芯片的VGA处理之后,生成RGB格式的原始视频数据,先缓存到片外的DDR,然后通过数据捕获模块将RGB原始数据捕获到片内,经过色彩空间转换模块(RGB2YUV)将原始的RGB格式的视频数据转换为YUV格式的数据,然后将Y、U、V数据用片内的存储资源进行缓存(FIFO),按照后级JPEG压缩格式的要求,按照BLOCK格式转换顺序,将BLOCK数据传递给后级JPEG IP,需要16个Y_FIFO,16个U_FIFO,16个V_FIFO,同时根据项目实践经验,针对最大分辨率(1920*1200)下,FIFO的深度为16384,宽度为8bits才能满足FIFO不会出现满的情况,不会丢数的情况。然后按照BLOCK的顺序输入给JPEG压缩IP(支持YUV444/YUV422/YUV420压缩格式),完成压缩之后将数据写入到DDR,EMAC(网卡)驱动读取完成压缩的数据,通过网络将视频数据传输至远程,进行远程显示。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.

在基板管理控制芯片视频压缩功能的设计中,自研子模块比较多,这些子模块设计逻辑比较复杂,是比较容易出错误的地方。同时因为VGA高分辨率下的时钟频率比较高,在FPGA原型验证的场景下是无法验证的,因此在真正的芯片流片回测的时候是有较大风险的,这是传统方案下的极大弊端或风险点。In the design of the video compression function of the substrate management control chip, there are many self-developed sub-modules. The design logic of these sub-modules is relatively complicated, and it is relatively easy to make mistakes. At the same time, because the clock frequency of VGA high resolution is relatively high, it cannot be verified in the FPGA prototype verification scenario. Therefore, there is a greater risk in the real chip tape-out backtest, which is extremely difficult under the traditional solution. Big disadvantage or risk point.

具体实施方式Detailed ways

为使本发明的目的、技术方案和优点更加清楚明白,以下结合具体实施例,并参照附图,对本发明实施例进一步详细说明。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.

基于上述目的,本发明的实施例的第一个方面,提出了一种基板管理控制芯片中视频功能调试的方法的一个实施例。图1示出的是该方法的示意性流程图。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.

如图1中所示,该方法可以包括以下步骤:As shown in Figure 1, the method may include the following steps:

S1响应于基板管理控制芯片进行流片回测,判断基板管理控制芯片的视频功能是否异常。芯片流片一般分为MPW流片和量产流片,MPW流片又称多项目晶圆流片,将多个具有相同工艺的集成电路设计放在同一晶圆片上流片加工,每个设计品种可以得到数十片芯片样品,用于产品研发阶段的实验和验证测试。MPW流片的费用由所有参加MPW的项目按照芯片面积分摊,实际成本仅为原来的5%-10%,极大地降低了集成电路研发阶段的成本和风险。本发明的应用场景就是针对MPW流片回归之后的测试,在测试过程中如果基板管理控制芯片的视频功能异常,且又无法定位是具体哪个模块出现的异常(设计异常)或者是否异常发生在后端设计、生产制造、封装过程中,就可以用本发明来排除是否是设计异常,以及异常出现的具体模块。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响应于基板管理控制芯片的视频功能异常,对基板管理控制芯片中的各个模块的功能进行检测。如图2所示,为基板管理控制芯片中的各个模块分别设置自检子模块,如果发现基板管理控制芯片的视频功能异常,则由驱动下发寄存器配置,使能视频功能SELF_CHECK(自检)功能。即每个自检子模块接受CFG_REGS的配置,使能每个子模块的自检功能。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响应于模块的检测结果为模块功能异常,对发生异常的模块进行代码修改。如果模块的检测结果是正常的,则不需要处理,如果模块的检测结果是异常的,则需要对模块的设计代码进行重新梳理修改,直到所有的模块功能都正常。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.

通过使用本发明的方案,能够极大提高基板管理控制芯片视频功能调试的速度,缩短项目周期,能够加快启动量产芯片的流程,确保量产芯片量产流片的成功。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.

在本发明的一个优选实施例中,进行检测的模块包括数据捕获模块、色彩空间转换模块、BLOCK转换模块和压缩数据输出模块。基板管理控制芯片中各个模块的功能如下,VGA将主机端的原始RGB数据写进DDR指定的空间(即Source_Data),然后DATA_CAP(数据捕获模块)去DDR中读取RGB数据,将读回的RGB原始数据输入到色彩空间转换模块(Color_Conver)进行色彩空间转换,转换成YUV格式的数据,然后YUV数据进入BLOCK_Gen模块,该模块按照后级JPEG IP的要求,产生BLOCK格式的数据,在JPEG IP完成YUV BLOCK数据的压缩后,经过CMP_DATA_OUT(压缩数据输出模块)写入到DDR中以供驱动读取。在基板管理控制芯片的视频功能异常时,需要对以上几个模块进行自检。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.

在本发明的一个优选实施例中,校验第二存储器中的视频数据包括:In a preferred embodiment of the present invention, verifying the video data in the second memory includes:

使用第一存储器中存储的待测试的视频数据校验第二存储器中的视频数据。The video data in the second memory is verified using the video data to be tested stored in the first memory.

在本发明的一个优选实施例中,待测试的数据包括一帧或多帧的视频数据,分辨率为640*480。In a preferred embodiment of the present invention, the data to be tested includes one or more frames of video data with a resolution of 640*480.

如图3所示,对自研模块DATA_CAP进行SELF_CHECK时,DATA_CAP_HW_CHECK子模块接收CFG_REGS的配置,使能对DATA_CAP模块的SELF_CHECK,此时DATA_CAP模块的数据来源从DDR切换到DATA_CAP_HW_CHECK。DATA_CAP_HW_CHECK子模块通过AHB_SLAVE接口接收软件或驱动下发的一帧或多帧视频数据(为加快处理速度,可用较小分辨率,比如640*480),将视频数据暂存到RAM_A中,DATA_CAP模块的AXI_MASTER接口去访问DATA_CAP_HW_CHECK子模块的AXI_SLAVE接口(在正常处理流程中DATA_CAP模块是通过AXI_MASTER接口去访问DDR的)获取一帧或多帧的视频数据,经过DATA_CAP模块处理(处理流程与正常处理流程一致),然后通过INTF接口输出到DATA_CAP_HW_CHECK子模块,值得注意的是,这个INTF接口与正常流程中输出到RGB2YUV的是一个接口,即保证DATA_CAP模块的接口以及内部运行的机制和功能与视频数据的正常处理是一致的。DATA_CAP_HW_CHECK子模块接收到视频数据后,暂存到RAM_B中以供驱动或软件读取。软件或驱动对读回的数据进行校验,值得注意的是DATA_CAP模块完成的是数据的捕获,并不修改数据,因此只需要对读回的数据与下发到RAM_A中的原始数据进行校验即可。如果校验结果一致,则判定DATA_CAP模块的功能是正常的。如果校验结果不一致,则判断DATA_CAP模块功能异常,需对设计代码重新梳理修改。As shown in Figure 3, when performing SELF_CHECK on the self-developed module DATA_CAP, the DATA_CAP_HW_CHECK sub-module receives the configuration of CFG_REGS and enables SELF_CHECK on the DATA_CAP module. 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.

At this time, the data source of the Color_Conver module is switched from the DATA_CAP module to the Color_Conver_HW_CHECK submodule. 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.

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.
