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.
