Optimal Partial Reconfiguration for Permanent Fault Recovery on SRAM-Based FPGAs in Space Mission

Abstract EN

In this paper, we present a technique to maximize the lifetime of SRAM-based FPGAs in space mission.

We focus on recovering permanent faults induced by SEE (single-events effect).

In our technique, we use a fix-sized fault detection module to detect permanent faults and propose a permanent fault recovery mechanism for fault recovery.

By using partial reconfiguration, we develop a system lifetime estimation model to find the optimal partition for designing the module-based fault recovering with the maximum system lifetime.

We conduct experiments with a set of real applications including SpaceWire, Wavelet, AC97, MEPG-4, 8086, and Ethernet on Xilinx XUP platforms.

The experimental results show our technique can effectively improve the lifetime compared with the previous work.
