System-Wide Energy Optimization with DVS and DCR

Abstract

In Chaps. 3 and 5, we described approaches and algorithms for employing DCR and DVS in real-time systems separately. However, as shown in Fig. 1.5, both processor and cache subsystem as well as other components contribute to the system’s overall power dissipation. Therefore, it is promising to employ DVS and DCR simultaneously to perform system-wide energy optimization.
