Secondly, linux is used as a complete operating system, and MMU (memory management unit) can be realized. The application of the method is specifically applied to the liquid crystal instrument, and an application layer and a system layer can be separated, so that software on two layers can be protected respectively. Even if one module of the application layer crashes, the operation of other modules and the system kernel is not affected.
Further: the split screen processing unit 11 includes:
the split screen processing circuit receives and outputs video signals transmitted by the MCU10 and split screen control signals of the HUD head-up display, and selects a split screen mode;
