ABSTRACT:
Apparatus, systems and methods for speculative scheduling of uops after allocation are disclosed including an apparatus having logic to schedule a micro-operation (uop) for execution before source data of the uop is ready. The apparatus further includes logic to cancel dispatching of the uop for execution if the source data is invalid. Other implementations are disclosed.
