The design complexity of modern high performance processors calls for innovative design techniques and methodologies for achieving time-to-market goals. New design techniques are also needed to curtail power increases that inherently arise from ever increasing performance targets. This paper describes new processor design and optimization approaches that bridge the gap between high performance and low power. These techniques are flexible as they rely on automated synthesis-centric optimizations to enable power reduction without sacrificing performance. These methodology innovations contributed to the industry leading performance of the POWERS processor. Copyright 2014 ACM.
