Abstract

Solutions for combined energy minimization and communication reliability control have to be developed for SoC networks. Redundant encodings and error-resilient protocols create new degrees of freedom for trading off energy against realiability and viceversa. In this chapter, the theoretical framework for energy and realiability analysis is introduced and several error control and recovery strategies are investigated in a realistic SoC setting. Furthermore, the chapter provides guidelines and methods to select the most appropriate error control scheme for a given reliability and/or energy efficiency constraint.
