基于PowerPC和X86的二余度非相似飞控计算机系统设计与实现
Design and realization of dual redundancy dissimilar flight control computer system based on PowerPC and Vortex86
摘要
Abstract
In order to avoid the common mode faults and improve the reliability of the flight control computer(FCC)sys-tem,the prototype system of dual redundancy dissimilar FCC was designed and realized. Hardware structure and principle of the system are given. The hardware structure includes the primary and redundant control computers with PowerPC and Vortex86 pro-cessor,two-port RAM for cross communication and arbitration module based on FPGA. As for the redundancy control software in the system,the software flow charts for engineering realization of the task synchronization and the arbitration processing soft-ware module are given. These are the core sections of the system. Based on the realization of the proposed system,a series of simulation experiments of the proposed approach were carried out to verify the feasibility of the system.关键词
