Abstract

Adaptive scaling digital techniques attempt to place the system close to the timing failure so as to maximize energy efficiency. Rapid recovery from potential failures is usually by slowing the system clock and/or providing razor solutions (instruction replay.) These techniques compromise the throughput. This application presents a technique to provide local in-situ fault resilience based on dynamic slack borrowing. This technique is non-intrusive (needs no architecture modification) and has minimal impact on throughput.
