Large instruction windows and issue queues are key to exploiting greater instruction level parallelism in out-of-order superscalar processors. However, the cycle time and energy consumption of conventional large monolithic issue queues are high. Previous efforts to reduce cycle time segment the issue queue and pipeline wakeup. Unfortunately, this results in(More)
Out-of-order superscalar processors require the ability to issue loads while older stores are in-flight. Forcing loads to wait for all older stores, including those on which they may not be dependent on, to retire and write to the cache would reduce IPC and take away almost all the benefit of out-of-order execution. On the other hand, maintaining functional(More)
