Fault-Tolerant Algebraic Architecture for radiation induced soft-errors

Abstract

Summary form only given. A novel fault-tolerant microprocessor capable of detecting and correcting radiation-induced soft errors is proposed and evaluated. The Fault-Tolerant Algebraic Architecture (FTAA) performs time redundancy intrinsically with computation, guaranteeing on-the-fly detection and correction of errors disrupting data and logic with minimum overhead. We evaluate the FTAA microprocessor in terms of performance, area, energy consumption, and fault coverage by performing an extensive design space exploration of the architecture.
