ABSTRACT:
A data-dependent branch table is a mechanism that is sensitive to operands that will be tested in order to determine branch action outcomes. The data dependent branch table operates in conjunction with a branch history table to anticipate those instances where the branch history table will make an erroneous prediction, and corrects the branch history table prior to the time that the actual prediction is made.
