Application-Aware Online Testing for Many-Core SoC
As the many-core system-on-chip becomes the predominant architecture in safety-critical applications, online testing will be required to ensure availability and reliability of these systems. To be accepted as a feasible solution, any online testing technique must satisfy time and power constraints while not interfering with concurrently running safety-critical applications. Previous research has not considered the effect of application interference during online test delivery, which can lead to increased application execution time and possible deadline misses - an unacceptable condition in safety-critical, hard realtime systems. In this paper, we propose and analyze two complementary methods of minimizing online testing interference with safety-critical applications. We show that test delivery blocking can eliminate interference at the cost of increased testing time, while test redundancy can reduce interference by 47％ while only increasing test delivery time by 15％ on average.
