Abstract

An out-of-order processorgroups program instructions together to control their commitment to complete processing. If an instruction within a group has a source operand dependent upon a plurality of destination operands of other instructions then this is identified as a size mismatch hazard. When the program instruction having the size mismatch hazard reaches a commit point within the processor, then it is flushed together with any speculatively executed succeeding program instructions. Furthermore, the group of program instructions containing the program instruction containing the program instruction having the size mismatch is divided into a plurality of groups of program instructions each containing a single program instruction which are then replayed through the processing mechanisms.
