CONTROL FLOW MECHANISM FOR EXECUTION OF GRAPHICS PROCESSOR INSTRUCTIONS USING ACTIVE CHANNEL PACKING

Abstract:

An apparatus to facilitate control flow in a graphics processing system is disclosed. The apparatus includes logic a plurality of execution units to execute single instruction, multiple data (SIMD) and flow control logic to detect a diverging control flow in a plurality of SIMD channels and reduce the execution of the control flow to a subset of the SIMD channels.
