Abstract:
An improved scheduling technique for software pipelining is disclosed which is designed to find schedules requiring fewer processor clock cycles and reduce register pressure hot spots when scheduling multiple groups of instructions (e.g. as represented by multiple sub-graphs of a DDG) which are independent, and substantially identical. The improvement in instruction scheduling and reduction of hot spots is achieved by evenly distributing such groups of instructions around the schedule for a given loop.
