This paper presents iRazor, a lightweight error detection and correction approach, to suppress the cycle time margin that is traditionally added to very large scale integration systems to tolerate process, voltage, and temperature variations. iRazor …
It is well known that technology scaling has led to increasing process/voltage/temperature/aging margins that substantially degrade performance and power in modern processors and SoCs. One approach to address these large timing margins is the use of …
Several methods that eliminate timing margins by detecting and correcting transient delay errors have been proposed. These Razor-style systems replace critical flip-flops with ones that detect late arriving signals, and use architectural replay to …
