Abstract

A hierarchical register file included in a hierarchical microprocessor that includes a plurality of execution clusters. An embodiment of the a hierarchical register file includes a first-level register file including a plurality of mappable registers. where the first level register filed is configured to allocate the mappable registers to store execution results of instructions executed by the execution clusters and provide secondary register storage for each of the execution clusters. The hierarchical register file also includes a plurality of second-level register files operatively coupled with the first-level register file, where the plurality of second-level register files are configured to store instruction operands and provide the instruction operands to respective execution units of the execution clusters for use in executing associated instructions. The hierarchical register file further includes a plurality of third-level register files operatively coupled with the first register file and respective second-level register files, where the third-level register files are configured to provide operands to execution units and capture immediate literal values.
