  • Publication number: 20240118900
    Abstract: An arithmetic processing device executes instructions by pipeline processing. In the arithmetic processing device, a branch predictor includes a prediction holder holding a prediction value of a consecutively taken branch count, a current taken branch count, and a prediction value of a remaining taken branch count for conditional branch instructions. A branch instruction issuance scheduler outputs an instruction refetch request upon a branch prediction miss of a conditional branch instruction held at an entry other than a head of a branch instruction completion queue holding branch instructions to be completed, and a repair request to the branch predictor for conditional branch instructions held between the entry and the head of the queue. In response to the requests, the branch predictor updates the prediction value of the remaining taken branch count for the conditional branch instructions corresponding to the repair request.

  • Publication number: 20240111833
    Abstract: A storing unit stores, amongst coefficients, values of a coefficient group associated with one selected from multiple variable groups, which are obtained by dividing state variables of an evaluation function. A searching unit searches for a solution to an optimization problem by repeating update processing, which includes calculating, using the values of the coefficient group, a value change of the evaluation function responsive to changing the value of each state variable of the variable group and changing the value of one state variable thereof based on the value change and temperature. A processing unit calculates multiplicity indicating the iteration count in which the values of the variable group are maintained in a search using Markov chain Monte Carlo (MCMC), and causes, responsive to cumulated multiplicity exceeding a threshold, the searching unit to perform the update processing using the values of the coefficient group associated with a different variable group.
