Future processors are expected to observe increasing rates of hardware faults. Using Dual-Modular Redundancy (DMR), two cores of a multicore can be loosely coupled to redundantly execute a single software thread, providing very high coverage from…
-
Field programmable gate arrays (FPGAs) provide designers with the ability to quickly create hardware circuits. Increases in FPGA configurable logic capacity and decreasing FPGA costs have enabled designers to more readily incorporate FPGAs in their…
