Abstract:
In this talk, I will present some recent research results on low hardware overhead techniques for permananent fault detection and fault recovery. The proposed techniques utilize a redundant URISC co-processor: an ultra reduced instruction set processor that executes only one Turing complete instruction. The URISC can be used to emulate any instruction in the ISA of the main, potentially faulty, processor, thus enabling full fault coverage. I will present a number of optimizations that allow us to use the URISC processor for fault detection and fault recovery with low performance penalty and low fault detection latency.
