摘要

The Register File (RF) is a particularly vulnerable component within processor core and at the same time a hotspot with high power density. To reduce RF vulnerability, conventional HW-only approaches such as Error Correction Codes (ECCs) or modular redundancies are not suitable due to their significant power overhead. Conversely, SW-only approaches either have limited improvement on RF reliability or require considerable performance overhead. As a result, new approaches are needed that reduce RF vulnerability with minimal power and performance overhead.
