Domestic SOC processor software design method

According to the domestic SOC processor software design method, software is divided into a driving layer in the longitudinal direction, and the driving layer comprises driving functions related to all hardware resources; the middle layer is a real-time operating system and comprises a kernel function related to processor hardware and a kernel function irrelevant to the processor hardware; the functional layer creates functional modules which need to be specifically realized by software, each functional module is a task, and memory resources are allocated for each task; the application layer performs task scheduling on the function modules of the function layer according to the working state and the use scene to realize real-time parallel processing of multiple tasks; a task stack and an interrupt stack are designed, field protection of the task execution process uses the task stack, field protection of the interrupt execution process uses the interrupt stack, and the task stack and the interrupt stack are mut
