METHODS OF BREAKING DOWN COARSE-GRAINED TASKS FOR FINE-GRAINED TASK RE-SCHEDULING

Abstract:

A method of scheduling instructions in a processing system comprising a processing unit and one or more co-processors comprises dispatching a plurality of instructions from a master processor to a co-processor of the one or more co-processors, wherein each instruction of the plurality of instructions comprises one or more additional fields, wherein at least one field comprises grouping information operable to consolidate the plurality of instructions for decomposition, and wherein at least one field comprises control information. The method also comprises decomposing the plurality of instructions into a plurality of fine-grained instructions, wherein the control information comprises rules associated with decomposing the plurality of instructions into the plurality of fine-grained instructions. Further, the method comprises scheduling the plurality of fine-grained instructions to execute on the co-processor, wherein the scheduling is performed in a non-sequential order.
