Abstract
Prediction of data values to be read from memory by a microprocessor for load operations. In one aspect, a method for predicting a data value that will result from a load operation to be executed by the microprocessor includes accessing an entry in a load value prediction table that stores a predicted data value corresponding to the load operation. The predicted data value is stored in a physical storage destination of the microprocessor to be available as a result of the load operation without waiting for execution of the load operation to complete. The storage destination is the destination for a loaded data value resulting from executing the load operation.
