The purpose of this paper is to evaluate the SEU sensitivity of a multi-core SoC working in two different multiprocessing modes. Radiation ground tests were performed with 14 MeV neutrons in GENEPI2 facility. The case study was a 45nm SOI multi-core processor having implemented error correcting code (ECC) and parity in their cache memories.
