Soft error has become a major adverse effect in CMOS based electronic systems. Mitigating soft error requires enhancing the underlying system with error recovery functionality, which typically leads to considerable design cost overhead, in terms of performance, power and area. For embedded systems, where stringent design constraints apply, such cost must be properly bounded. In this paper, the authors propose a HW/SW methodology DHASER, which enables efficient error recovery functionality for embedded ASIP-based multi-core systems. DHASER consists of three main parts: Task Level Correctness (TLC) analysis, TLC-based processor/core customization, and runtime reliability-aware task management mechanism.
