General Purpose NanoComputing Systems

Novel Reliability-Aware Performance Enhancing Microarchitectural Techniques

Picture of simulated performance improvements for reliability driven speculation
Blue bars show the IPC (Instructions Per Cycle) for a machine with reliability-aware microarchitectural techniques. Red bars show the IPC for a machine without these techniques. For each benchmark 6 different technology scalings were simulated. The technologies are sorted in decreasing reliability order. We observe that reliability-aware microarchitectures are necessary to sustain performance as the probability of errors increases.
