Popis:	Energy consumption has become an increasingly design issue in multimedia mobile system. This paper presents a realization for suspend/resume on a dual-core SoC to conserve energy consumption while system is idle.A generic backup/restore mechanism is proposed for any DSP applications. Furthermore, optimization for latency targets on characteristic of H.264/AVC decoder is refined and only needs to backup 26 words for resume.Experimental results show optimization scheme can achieve 99% improvement in latency and the realization for suspend/resume can provide a valuable experience for similar designs.
