Design and Research of Embedded System Software Based on MCU Platform

Embedded system requires high reliability and real-time performance. And the fairly good reliability and real-time performance are the important standard of embedded system design. In order to make software system more robust, an excellent software architecture is required in the design of embedded system. In this paper, the software architecture method of embedded system based on the MCU platform is introduced. Event-driven mechanism is applied to meet design requirement. Priority scheduling mechanism is applied to the main program, and together with the corresponding software anti-interference measures, so that the stability and reliability of this system are improved. Through comparing of the advantages and disadvantages of those methods suggested above, we draw a conclusion that the software building method of embedded system based on the MCU platform is feasible.
