Abstract:
This paper designs and implements the inter-process communication of the flight control system based on RTLinux. According to the design task, with the good performance of the real-time FIFO provided by RTLinux and the advantage of reducing data copying of the shared memory, considering the efficiency of real-time requirements, it combines several communication mechanisms. It solves the issue of complex inter-process communication in the flight control system, and metes the demand of both real-time and efficiency.
