Abstract
In a processing core, a newly received load instruction may be dependent upon a previously received store instruction. The core may include a predictor to predict such dependencies and provide an identification of a colliding store instruction. The load instruction may be stored in a scheduler with a dependency marker. Thereafter, the load instruction may be prevented from executing until after execution of the colliding store. Upon execution of the load, the accuracy of the prediction is confirmed. Upon retirement of the load instruction, new prediction results may be provided to the predictor.
