In this paper a novel technique is proposed for online detection of timing interference in multicore architectures.The technique is aimed at mixed-criticality workloads. This paper describes a method to use hardware performance counters to detect such misbehaviors. Experimental data is gathered, showing the viability of this method. The method can be used as safety-net in several scheduling approaches.

In this paper we present a Concurrent Error Detection (CED) technique that can be applied to behavioral RTL models of data dominated systems. The technique obtains CED through duplication of operations with shifted operands. Duplication is performed according to transformation rules that can automatically be applied to a behavioral model. Preliminary experimental results show the viability of the proposed technique.
