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 provided as a result of the load operation without waiting for execution of the load operation to complete based on a confidence parameter stored in the entry compared to a dynamic confidence threshold.
