Abstract
A processorfor performing out-of-order execution of a stream of program instructions includes a special register access pipeline for performing status access instructions accessing a status register. In order to serialise these status access instructions relative to other instructions within the system access timing control circuitrypermits dispatch of other instructions to proceed but controls the commit queue and the result queue such that no program instructions in program order succeeding the status access instruction are permitted to complete until after a trigger state has been detected in which all program instructions preceding in program order the status access instruction have been performed and made any updates to the architectural state. This is followed by the performance of the status access instruction itself.
