Abstract
A dispersal unit in combination with a chain affinity unit and an intra-cycle dependency analyzer routes instructions in a microprocessor in order to improve microprocessor performance. The dispersal unit routes instructions to a particular cluster in the microprocessor in response to information stored in the chain affinity unit. The intra-cycle dependency analyzer identifies dependencies in groups of instructions to the dispersal unit, and the dispersal unit routes instructions in the group based on those dependencies.
