  • Repartitioning and reordering of multiple threads into subsets based on possible access conflict, for sequential access to groups of memory banks in a shared memory
    Patent number: 9626218
    Abstract: Circuitry for dynamically ordering the execution of multiple threads in parallel is presented. The circuitry may include a control circuit that controls the execution of multiple subsets of threads using multiple processing units in parallel. Each of the plurality of processing units may be associated with an adjustable order thread issuer that may receive a subset of threads and an order in which to execute the subset of threads from the control circuit. The adjustable order thread issuer may manage the processing unit by providing each thread from the subset of threads for execution to the processing unit in the specified order. The adjustable order thread issuer may adjust the order in which threads are issued in an effort to optimize shared resource usage and thus improve the performance of a multithreaded application.

  • Method and apparatus for performing automatic decoupling capacitor selection for power distribution networks
    Patent number: 9582628
    Abstract: A method for designing a power distribution network (PDN) for a system implementing a target device includes computing a target PDN impedance value for the PDN. For each switching frequency of the target device where an effective PDN impedance value for the PDN is greater than the target PDN impedance value, one or more decoupling capacitors for one or more capacitor types are identified to add to the PDN to drive the effective PDN impedance value below the target PDN value. A selection of decoupling capacitors identified is refined to reduce one or more of a cost of the PDN and space required for implementing the PDN.
