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)
The IBM POWER6e microprocessor core includes two accelerators for increasing performance of specific workloads. The vector multimedia extension (VMX) provides a vector acceleration of graphic and scientific workloads. It provides single instructions that work on multiple data elements. The instructions separate a 128-bit vector into different components(More)
