The impact of low-power techniques on the design of portable safety-critical systems

Abstract

The application of typical low-power techniques on safety-critical systems may result in degradation of crucial safety properties of the system. However, existing techniques to address this impact, considered that low-power mode is applied for short time intervals. Thus, addressing degradation of the safety properties only on checkers was considered sufficient. A novel approach is introduced that considers both requirements for safe operation and low-power dissipation. The benefits of this approach are exhibited and a comparison to alternative approaches is offered. © Springer-Verlag 2004.
