摘要: A processor includes a multiple stage pipeline with a scheduler with a wakeup block and select logic. The wakeup block is configured to wake, in a first cycle, all instructions dependent upon a first selected instruction to form a wake instruction set. In a second cycle, the wakeup block wakes instructions dependent upon the wake instruction set to augment the wake instruction set. The select logic selects instructions from the wake instruction set based upon program order.

摘要: Methods and systems that reduce the number of instance of a shared resource needed for a processor to perform an operation and/or execute a process without impacting function are provided. a method of processing in a processor is provided. Aspects include determining that an operation to be performed by the processor will require the use of a shared resource. A command can be issued to cause a second operation to not use the shared resources N cycles later. The shared resource can then be used for a first aspect of the operation at cycle X and then used for a second aspect of the operation at cycle X+N. The second operation may be rescheduled according to embodiments.
