In order to meet the needs of high performance, high integration of future space missions to the onboard computer requirements, this paper presents a reconfigurable onboard computer system structure based on multi-processor system on chip( MPSOC) . It is composed of standard processors, application processors, reconfigurable module, special ASIC and I/O interface, by using MPSOC, it can meet the different application mode and data processing requirements of the satellite, so that the parallelism and the processing performance of computers are im-proved. At the same time the on-board computer uses a hardware-software collaborative design method, which can improve the system performance and reliability, and shorten the development cycle.
