"abstract" in order to reduce the development difficulty of DSP system software, to ensure the real-time nature of the system, shorten the development cycle, the embedded real-time operating system Μc/os-ⅱ porting to the DSP chip is a common method at present. This paper introduces the characteristics of embedded real-

Implement a simple Embedded Operating System (1) Implement an embedded operating system that can't do anything1. First determine the CPU. Here we use embedded CPU for simplicity, such as the arm series. The reason why we use a short Instruction Set)The convenience of a type of CPU is that there is no disti
