Out-of-order execution significantly increases the performance of superscalar processors. The out-of-order execution mechanism is, however, energy-inefficient, which inhibits scal...

In this paper, we present a novel technique to reduce dynamic and static power dissipation in the issue queue. The proposed scheme is based on delaying the dispatch of instructions...
With faster CPU clocks and wider pipelines, all relevant microarchitecture components should scale accordingly. There have been many proposals for scaling the issue queue, registe...
Dynamic instruction scheduling logic is one of the most critical components of modern superscalar microprocessors, both from the delay and power dissipation standpoints. The delay ...

In an out-of-order issue processor, instructions are dynamically reordered and issued to function units in their dataready order rather than their original program order to achiev...
The instruction scheduling logic used in modern superscalar microprocessors often relies on associative searching of the issue queue entries to dynamically wakeup instructions for...

In a dynamic reordering superscalar processor, the front-end fetches instructions and places them in the issue queue. Instructions are then issued by the back-end execution core. T...
The last few years have witnessed an unprecedented explosion in transistor densities. Diminutive feature sizes have enabled microprocessor designers to break the billion-transisto...
