摘　　要：在我国空间通信技术取得巨大发展的今天,对空间飞行器电子设备功能可重构、可升级、运行代码可更换的需求越来越多。分析了空间辐射效应对高性能数字信号处理器(DSP)和SRAM型FPGA的影响,提出了一种适用于空间飞行器上的可重构信息处理平台的硬件设计方法,具有可重构、可在线升级运行代码的特点。该硬件架构计由高性能DSP和高可靠性的反熔丝FPGA为主要组成,提出了这种架构对抗空间单粒子效应的方法。该电路设计方法可以为空间飞行器通信设备的设计提供参考。Space communication technology in China has achieved great development today, more and more demands for reconfigurable, scalable and replaceable running code for the space vehicle electronic equipment are raised. This paper analyzes the space radiation effects on the high performance digital signal processor （DSP） and SRAM type of FPGA, proposes a method for the spacecraft on a reconfigurable information processing hardware design, which has reconfigurable characteristic and could upgrade operation code online. The hardware architecture is mainly composed of high performance and high reliability of the DSP antifuse FPGA. Then the method for the structure against space single particle effect is proposed, thus to provide reference for the design of space vehicle communication equipment.
