Abstract: A mechanism for handling exceptions in a processor system that issues a family of more than one instruction during a single clock that utilizes the exception handling procedures developed for single instructions. The mechanism detects an exception associated with one of the instructions in the family, inhibits the data writes for the instructions in the family, flushes the pipeline, and reissues the instruction singly. The exception handling procedure for the single instruction may then be utilized.

Abstract: PAIRED INSTRUCTION PROCESSOR BRANCH RECOVERY MECHANISM A mechanism for recovering from a branch misprediction in a processor system that issues a family of more than one instruction during a single clock that determines the location of the branch instruction in the family, completes the data writes for all instructions in the family preceding the branch instruction, inhibits the data writes for all instructions in the family following the branch instruction, and fetches the correct next instruction into the pipeline.
