Abstract
The invention provides techniques for reducing the port pressure of a clustered processor. In an illustrative embodiment, the processor includes multiple clusters of execution units, with each of the clusters having a portion of a register file and a portion of a predicate file associated therewith, such that a given cluster is permitted to write to and read from its associated portions of the register and predicate files. A duplicator interconnection technique in accordance with the invention reduces port pressure by providing one or more global move units in the processor. A given global move unit uses an inter-cluster move instruction to copy a value from a portion of the register or predicate file associated with a source cluster to another portion of the register or predicate file associated with a destination cluster.
