METHOD AND APPARATUS FOR MOVING DATA FROM A SIMD REGISTER FILE TO GENERAL PURPOSE REGISTER FILE

WIPO Patent Application WO/2012/068475

A3

A method for moving data from a first register file in a computational unit (808i) to a second register file in a processor (1410) is provided. The state of a signal on a data movement lead (risc is mfwr) is changed to indicate the data movement instruction from a first register file in a computational unit to a second register file in a processor (1410). A lane address from the processor to the computational unit is provided over a first address lead (risc is ua). A read address from the processor to the computational unit is provided over a second address lead (risc is ra), and data is transferred from the first register file in the computational unit to the second register file in the processor over a data interface lead (node regf rd).
