An Experimental Method for Evaluating the SEU of Radiation-Hardened DSP

This paper presents a new experimental method to evaluate the SEU performance of radiation-hardened DSP. The method includes three ways of solely detecting SRAM, detecting regs by CPU and function-detecting. Software and hardware detection systems are designed by the method, and SEU experimental test was done on HI-13 heavy-ion accelerator. The results show that the error rate of DSP is about 1.8E-12 error/bit·day(GEO) under irradiation dose of 1.0E+7 icons/cm², which means the experimental method can be used for well evaluating the SEU performance of DSP.
