Bubble Razor: Eliminating Timing Margins in an ARM Cortex-M3 Processor in 45 nm CMOS Using Architecturally Independent Error Detection and Correction

We propose Bubble Razor, an architecturally independent approach to timing error detection and correction that avoids hold-time issues and enables large timing speculation windows. A local stalling technique that can be automatically inserted into …

Bubble Razor: An architecture-independent approach to timing-error detection and correction

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 …
