As semiconductor processing technology continues to scale down, managing reliability becomes an increasingly difficult challenge in high-performance microprocessor design. Transient faults, also known as soft errors, corrupt program data at the circuit level and cause incorrect program execution and system crashes. Future processors will consist of billions of transistors organized as multi-core microarchitectures. Packaging multiple cores onto the same die exposes more devices to soft error strikes. This paper explores utility-function-driven cross domain optimization for both performance and reliability.
