  • Uniform external and internal interfaces for delinquent memory operations to facilitate cache optimization
    Patent number: 8886887
    Abstract: A computer implemented method, software infrastructure and computer usable program code for improving application performance. A delinquent memory operation instruction is identified. A delinquent memory operation instruction is an instruction associated with cache misses that exceeds a threshold number of cache misses. A directive is inserted in a code region associated with the delinquent memory operation to form annotated code. The directive indicates an address of the delinquent memory operation instruction and a number of memory latency cycles expected to be required for the delinquent memory operation instruction to execute. The information included in the annotated code is used to optimize execution of an application associated with the delinquent memory operation instruction.

  • Scheduling technique for software pipelining
    Patent number: 7930688
    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.
