With the scaling of technology and the need for higher performance and more functionality, power dissipation is becoming a major bottleneck for microprocessor designs. Because clock power can be significant in high-performance processors, we propose a deterministic clock-gating (DCG) technique which effectively reduces clock power. DCG is based on the key observation that for many of the pipelined stages of a modern processor, the circuit block usage in the near future is known a few cycles… CONTINUE READING
