The invention discloses a reversing image display system based on a multi-core heterogeneous SoC (System on Chip). The system comprises a lightweight sub-operation system; a heavy-weight sub-operating system; the lightweight sub-operating system transmits data with the heavy sub-operating system through the inter-core communication module; the image acquisition module is used for acquiring image data; the display control module is used for displaying the reversing image; when the lightweight sub-operation system is started, the lightweight sub-operation system obtains image data and controls the vehicle-mounted screen to display a first reversing image based on the image data; and when the heavy-weight sub-operating system is started, the dummy driving module in the heavy-weight sub-operating system sends an input/output control instruction to the light-weight sub-operating system through the inter-core communication module so as to obtain image data, and meanwhile, the vehicle-mounted screen displays a second reversing image based on the image data. The invention further provides a reversing image display method based on the multi-core heterogeneous SoC, the reversing image can be quickly displayed, and the cost can be saved.

    一种基于多核异构SoC的倒车影像显示系统,包括:轻量级子操作系统;重量级子操作系统;核间通信模块,轻量级子操作系统通过核间通信模块和重量级子操作系统进行数据的传输;影像采集模块,其采集影像数据;以及显示控制模块,其显示倒车影像;当轻量级子操作系统启动时,轻量级子操作系统获取影像数据,并基于影像数据控制车载屏幕显示第一倒车影像;当重量级子操作系统启动时,重量级子操作系统中的哑驱动模块通过核间通信模块向轻量级子操作系统发送输入输出控制指令,以获取影像数据,同时基于影像数据使车载屏幕显示第二倒车影像。本申请还提供一种基于多核异构SoC的倒车影像显示方法,可以快速显示倒车影像,且可以节约成本。
