Research on a Reconfigurable Architecture of Onboard Computer

为满足未来航天任务对星载计算机的高性能、高集成化的要求,本文提出了一种基于MPSOC的可重构星载计算机体系结构,由标准处理器、应用处理器、可重构模块、专用ASIC、I/O接口构成,采用片上多处理器系统能够满足卫星不同的应用模式和数据处理要求,从而提高计算机的并行性和处理性能。同时星载计算机采用一种软硬件协同设计方法,可提升系统性能和可靠性,并缩短研制周期。

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.
