Design of Multiprocessor for Flight Control and Management

China's areonautical industry now needs a multiprocessor to be used for flight control and management. In the absence of detailed information in the open literature we have searched, we present here our design of such a multiprocessor, which is believed to be the first one designed in P. R. China. After hundreds of flights our design is proved to be successful.Fig. 1 shows the system schematic of our design. The features of our design are:(1) Good self-testing capability. For example, microprocessor 1 (Fig. 1) can automatically send out alarm if it is not working properly; moreover; it can also send out alarm if drive 1 is not working ploperly.(2) Good reliability of control of access to common resources. The main technical measures for achieving such reliability are: suitable priorities and time slots are prescribed for access; hardware is so designed as to control the path of access.(3) Raliable circuits for achieving fault location. For example, Fig. 2 shows how this is done for microprocessor 1.
