动态可重配置的星上嵌入式实时计算系统

Dynamically Reconfigurable Embedded Real-time Computing System on Satellite

卫星上由于特殊条件的限制,计算机处理速度满足不了对信号处理的需要,而且不能在有限的硬件规模和功耗的情况下灵活地实现各种计算处理功能。提出了一种基于嵌入式微处理器配合大规模现场可编程门阵列(FPGA)的动态可重配置结构的星上实时计算系统的体系结构设计,可在一块FPGA资源上通过动态重配置实现不同的信号处理功能。实际应用证明,处理速度和性能得到了大幅度提高。

At present, the speed of the micro-processor on the satellite cannot satisfy the need for the signal processing ability, and the high degree of flexibility can＇t be obtained based on the limited hardware resource and power consuming. An architecture dedicated to real-time signal computing system on satellite with dynamically reconfignrable architecture based on the embedded micro-processor and large scale Field Programmable Gate Arrays （FPGA） is presented. Based on the architecture, one piece of FPGA can be reconfignred dynamically to execute various signal processing algorithms. And the real application shows that the performance and computing speed can be improved in large range.
