Abstract

This paper presents a unified approachwhich allows efficient concurrent tests to beconsidered when synthesizing scalable signalprocessing multiprocessor architectures. Theapproach is based on two earlier works. Thefirst work has allowed the synthesis of scalablemultiprocessor architectures where comparisontesting is considered. The second work hasshown the feasibility of using a softwaretechnique called Mutation testing tosuccessfully test hardware devices. Thepresented approach ensures that VLSI digitalsignal processors (DSP) are totally testedconcurrently within useful computation. Basedon realistic examples of signal processingapplications and state-of-the-art DSPs, theapproach is shown highly efficient in terms offault coverage and fault latency.
