A data processing system, circuit arrangement, integrated circuit device, program product, and method dispatch multiple copies of a producer instruction to multiple execution units in a processor whenever it is determined that the producer instruction has or is likely to have multiple consumer instructions that are dependent on the producer instruction. Thus, when the multiple consumer instructions are subsequently dispatched to the multiple execution units, the results of the producer instruction are available within those execution units, and without the necessity for any inter-execution unit or inter-microcluster result forwarding. The decision of whether to dispatch multiple copies of a producer instruction may be made at runtime, e.g., within the dispatch unit of a processor, or in the alternative, may be made during compilation of a computer program to be executed on a multi-execution unit processor.

[ What is claimed is:] [1.]1. A circuit arrangement, comprising:(a) a plurality of execution units, each execution unit configured to execute instructions supplied thereto; and(b) a dispatch unit, coupled to the plurality of execution units, the dispatch unit configured to determine whether to dispatch multiple copies of a producer instruction to multiple execution units the dispatch unit further configured to determine whether the producer instruction is likely to have multiple consumer instructions associated therewith.
