Abstract

A method and apparatus for rescheduling operations in a processor. More particularly, the present invention relates to optimally using a scheduler resource in a processor by analyzing, predicting, and sorting the write order of instructions into the scheduler so that the duration the instructions sit idle in the scheduler is minimized. The analyses, prediction, and sorting may be done between an instruction queue and a scheduler by using delay units. The prediction can be based on history (latency, dependency, and resource) or on a general prediction scheme.
