Dynamic power dissipation is a major field where various researches have been held to reduce the energy consumption in present clocked systems. Here we discuss the various tiers of power management in design followed by a treatise on dynamic power dissipation in CMOS circuits and power efficient cache designs under research. We further propose a technique in reducing the clock frequency of circuits without compromising the performance. This is achieved by using a dual-edged clock for the operation, allowing the operating frequency to be halved, which immediately translates into a tremendous gain in power efficiency. The applications of this technique in processor caches are also studied. The designs proposed herein were implemented using Verilog HDL and the power requirements analyzed using Xilinx XPower 10.1. Experimental results and the conclusions drawn are included. © 2009 IEEE.
