Abstract

Caches are vitally important for the performance in modern CPUs. But they also bear great potential for malfunction when put under irradiation. Hence, trade-offs have to be made for either performance or reliability.In this paper we present a deeper insight on the CPU caches, their influence in a running operating system and possible reasons for their malfunction. Therefore, a proton source with 230 MeV was used to target an ARM Cortex A9 in a Zynq-7000, running an embedded Linux with KGDB. As a result, we tested three different cache configurations, which showed three distinct error cases. This can help to improve the understanding of system malfunctions due to radiation and build useful mitigation techniques.
