Abstract

Argus, a novel approach for detecting errors in simple processor cores, dynamically verifies the correctness of the four tasks performed by a von Neumann core: control flow, data flow, computation, and memory access. Argus detects transient and permanent errors, with far lower impact on performance and chip area than previous techniques.
