    摘要: A system and method for issuing a processor instruction to multiple processing sections arranged in an out-of-order processing pipeline architecture. The multiple processing sections include a first execution unit with a pipeline length and a second execution unit operating upon data produced by the first execution unit. An instruction issue unit accepts a complex instruction that is cracked into respective micro-ops for the first execution unit and the second execution unit. The instruction issue unit issues the first micro-op to the first execution unit to produce intermediate data. The instruction issue unit then delays for a time period corresponding to the processing pipeline length of the first execution unit. After the delay, a second micro-op is issued to the second execution unit.

    摘要: A non-quiescing key setting facility is provided that enables manipulation of storage keys to be performed without quiescing operations of other processors of a multiprocessor system. With this facility, a storage key, which is accessible by a plurality of processors of the multiprocessor system, is updated absent a quiesce of operations of the plurality of processors. Since the storage key is updated absent quiescing of other operations, the storage key may be observed by a processor as having one value at the start of an operation performed by the processor and a second value at the end of the operation. A mechanism is provided to enable the operation to continue, avoiding a fatal exception.
