Abstract

A technique of energy minimization by combining dynamic voltage scheduling (DVS) and adaptive body biasing voltage (ABB) method for distributed real-time system at system design level is proposed. Based on a simplified energy optimizing model, the proposed approach named LEVVS (low energy supply voltage and body biasing voltage scheduling algorithm) explores the minimizing of energy consumption by finding optimal trade-off between dynamic and static energy. Experiments show that, using the LEVVS approach, more than 53% average energy reduction can be obtained than by employing the DVS method alone. Furthermore the effects of switch capacitance and global slack on the energy saving efficiency of LEVVS are investigated.
