摘要
Abstract
To address the failure of digital signal processors(DSP)in spaceborne radar caused by single event upsets induced by high-energy charged particles,a DSP reinforcement design scheme against single event upsets is proposed from three dimensions:software,hardware and system.This scheme adopts design methods such as triple modular redundancy(TMR)for key program variables,bootloader verification and error correction,periodic refresh of control registers,error detection and correction(EDAC)and watchdog design,ensuring that the system can load successfully and operate normally when a single event upset occurs in the DSP.The fault injection tests demonstrate that after this scheme is adopted,the whole DSP loads successfully,and that when a single event up-set occurs,the recovery success rate of the DSP system reaches 99.6%,with the average fault recovery time being approximately 10 s.关键词
