Single event upsets (SEU) is a major concern in space-borne electric system, result in crashing of application programs and considerable economic losses. To satisfy with the requirements of future space computers, this paper designs a high reliable SOC: Longteng-FT-SOC, which is based on a SPARC V8 compatible microprocessor. Several high reliable schemes such as direct error correction pipeline, a reliable cache controller based on grouped checking and an automatic recovery memory controller, are proposed. The experimental results preliminarily show that the Longteng-FT-SOC we designed is reliable and can tolerate SEU up to 300 Krads (Si).
