Preliminary results of SEU fault-injection on multicore processors in AMP mode

Abstract:

The current technological challenge for computing systems is to use multicore processors in order to ensure reliability, improve performance, and reduce power consumption. This paper presents a method and preliminary results of SEU fault-injection campaigns performed on multicore systems in asymmetric multi-processing mode. The target used for this purpose was a Quad-core processor. This work aims at validating the efficiency of TMR fault-tolerance method and to show the weakest variables of a given application running over multicore systems. © 2014 IEEE.
