Because of technology scaling, soft error rate has been increasing in modern processors, affecting system reliability. To mitigate such effect, we propose an adaptive fault tolerance approach that exploits, at run-time, idle functional units to execute duplicated instructions in a configurable VLIW processor. In applications with high Instruction Level Parallelism (ILP) and few functional units available for duplication, it adaptively reschedules instructions according to a configurable… CONTINUE READING
