Abstract
A system and method for linking speculative results of load operations to register values. A system includes a memory file including an entry configured to store a first addressing pattern and a first tag. The memory file is configured to compare the first addressing pattern to a second addressing pattern of a load operation, and to link a data value identified by the first tag to a speculative result of the load operation if there is a match. The system further includes an execution core coupled to the memory file and configured to access the speculative result when executing a second operation that is dependent on the load operation, and a load store unit coupled to the memory file and configured to verify the link between the data value and the speculative result of the load operation by performing a comparison between one or more addresses.
