Abstract

Energy dissipation from the issue queue and register file, constitutes a large portion of the overall energy budget of an aggressive dynamically scheduled microprocessor. We propose techniques to save energy in these structures by reducing issue queue occupancy and by reducing unnecessary register file accesses that can result from speculative scheduling. Our results show a 44% reduction in issue queue occupancies and an 87% reduction in register file accesses for scheduling replays. Our data show that these savings can translate into a 52% saving in issue queue energy, a 13% savings in register file energy, and a 22% overall energy savings.
