FPGA pre-layout plan for reconfigurable on-board information processing system

In order to enhance the FPGA utilization ratio and the long-term reliability of reconfigurable satellite information processing system, this paper has proposed a FPGA resource pre-layout plan, which is based on the analysis of FPGA inner architecture and the FPGA resource usage by typical tasks. The proposed plan also analyzed the on-board reliability in theory. The simulation result showed that, the plan might greatly enhance the FPGA resource utilization rate by up to 30%. Further, it also improved the FPGA resource utilization rate round about 50% when FPGA had permanent fault locally.
