ABSTRACT:
A computer system facilitates efficient mixing of multiple sub-word items. Mixing circuitry is connected to a plurality of registers and a result register. The mixing circuitry mixes multiple sub-word items packed into the plurality of registers. The multiple sub-word items, when mixed, are placed in the result register. In the preferred embodiment, the mixing circuitry is implemented using a plurality of multiplexors. Control circuitry, connected to the control inputs of the multiplexors, generates control signals which control the mixing of multiple sub-word items by the multiplexors.
