Memory mapped register file and method for accessing the same

摘要

A data processing system comprises a processor to process instructions. A plurality of pipeline stages to execute instructions including a register file. The register file includes a memory unit having a plurality of memory locations, each memory location being addressable by an encoded address. The encoded address corresponds to at least one register and processing mode. Input ports receive inputs for addressing at least one of the memory locations using an encoded address. Output ports to output data from at least one of the memory locations using an encoded address.
