China-made Cpu Space Computer Applications

Space computer is the core of the spacecraft , it's mainly used in the cortrol ofcalculation, management of affairs and pretreatment of sensitive data. Because of thelimit of homemade component in the former years, at present the CPU of the aerocraftin flight isn't homemade. In recent years, with the development of the IC industry, in2002 FuDan micro-electronics develop high-powered embedded processor-JFM80386EX, and it passed the identification of the department of equipment and thedepartment of information industry in 10.10.2003.This computer system useJFM80386EX as it's CPU, and it's the first design of aerospace computer based on thehomemade CPU. After having investigated correlated information and used the correlated designof our laboratory for reference, we have developed a computer system which is highperformance, reliable and reconfigurable, based on the homemade JFM80386EX CPU.386EX CPU of FuDan micro-electronics is the core of the hardware .1553B Bus is theexternal interface in this computer. The JFM386EX aerospace computer systemcomplete the EDAC (Error Detection and Correction ) function. The Real TimeOperation System(RTOS) VxWorks of Windriver is the core of the software. We haveachieved the system's theory project, schematics, PCB drawings, hardwaredebugging .What's more, we made stability groundwork for the final application ofsubsequent spaceflight projects. The fruits of this project and the former design provide a homemade spacecomputer system of middling management capacity. It can be applied to mannedspacecraft , space scientific exploration, networks of satellites and so on. It is mostsignificant to the development of our country's space science and technology.
