Abstract
The present invention is a method for processing instructions by decomposing a macroinstruction into at least two microinstructions, executing the microinstructions in parallel, and linking the microinstructions such that they appear as though they were executed as a single functional unit. The present invention operates by determining whether certain exceptions occur in either of the functional units, according to SSE rules for exceptions. If an exception does occur in any of the linked microinstructions, then the execution of each of those microinstructions is canceled. This avoids the necessity of a back-off or undo mechanism.
