Leakage power is a major concern in current and future microprocessor designs. In this paper, we explore the potential of architectural techniques to reduce leakage through power-gating of execution units. This paper first develops parameterized analytical equations that estimate the break-even point for application of power-gating techniques. The potential(More)
Clock-gating has been introduced as the primary means of dynamic power management in recent high-end commercial microprocessors. The temperature drop resulting from active power reduction can result in additional leakage power savings in future processors. In this paper we first examine the realistic benefits and limits of clock-gating in current generation(More)
In a circuit environment that is becoming increasingly sensitive to dynamic power dissipation and noise, and where cycle time available for control decisions continues to decrease, locality principles are becoming paramount in controlling advancement of data through pipelined systems. Achieving fine grained power down and progressive pipeline stalls at the(More)
We offer a technique to partition a centralized control-flow graph to obtain distributed control in the context of asynchronous high-level synthesis. The technique targets Huffman-style asynchro-nous controllers that are customized to the problem. It solves the key problem of handling signals that are shared between the partitions—a problem due to the(More)
