In most modern processor designs the L1 data cache has become a major consumer of power due to its increasing size and high frequency access rate. In order to reduce this power consumption, we propose in this paper a straightforward filtering technique. The mechanism is based on a highly accurate forwarding predictor that determines if a load instruction will take its corresponding data via forwarding from the load-store structure
