Abstract
A branch recovery mechanism completes the processing of a concurrently issued family of instructions depending on the location of the branch instruction in the family and on whether the branch was correctly predicted. If the branch was not correctly predicted, the writes and stores of instructions in the family the precede the branch instruction are completed and those instructions are retired. However, the writes and stores of the instructions in the family following the branch instruction are inhibited.
