DSP with register file and multi-function instruction sequencer for vector processing by MACU

Year	Description
1996	Invention patented by John G. Bartkowiak on May 5th, 1996. Abstract: A DSP including a register file connected to data memories and functional units is provided. Functional units read operands from the register file and store results into the register file. Various register storage locations form communicative links between the functional units and the memories, in accordance with a particular code sequence being executed by the DSP. Because each functional unit has an independent path to the register file, each functional unit may provide results to the register file concurrently. Additionally, having multiple register storage locations which are accessible to any functional unit permits flexibility in the operation of the DSP. Multiple register storage locations may be used by the same functional unit, allowing program code to be more optimized by storing values for later use in one of the register storage locations, as opposed to storing values in the data memories. The register file essentially provides a buffer between the functional units, and between the functional units and memory.
