Energy-Aware Code Replication for Improving Reliability in Embedded Chip Multiprocessors

Abstract

Embedded chip multiprocessors (ECM) present unique challenges in terms of both hardware design and software construction. One of these challenges is to balance out the often-conflicting demands of performance, power, reliability, and memory space consumption. Therefore, there is a clear need for optimization techniques that consider multiple factors and metrics at the same time. This paper explores the energy-aware reliability support for the ECM architectures, targeting in particular at array-intensive embedded applications and transient errors. More specifically, we propose a compiler-directed energy-aware code replication scheme for the ECM architectures.
