ARITHMETIC PROCESSING DEVICE AND METHOD OF CONTROLLING ARITHMETIC PROCESSING DEVICE

摘要

An arithmetic processing device includes a plurality of arithmetic processing units each including, an internal circuit that, in an instruction processing state in which an instruction is processed, processes the instruction and that, in an instruction processing stopped state in which instruction processing is stopped, transitions to a state of power save operation, and a power control circuit that disables the power save operation; and a monitoring circuit that monitors the instruction processing stopped state of the plurality of arithmetic processing units and counts the number of the arithmetic processing units in the instruction processing stopped state. The power control circuit of each of the plurality of arithmetic processing units disables the power save operation of the arithmetic processing unit in the instruction processing stopped state, in a case where the number of the arithmetic processing units in the instruction processing stopped state exceeds a threshold.

1. An arithmetic processing device comprising:
a plurality of arithmetic processing units each including,
an internal circuit that, in an instruction processing state in which an instruction is processed, processes the instruction and that, in an instruction processing stopped state in which instruction processing is stopped, transitions to a state of power save operation; anda power control circuit that disables the power save operation; and a monitoring circuit that monitors the instruction processing stopped state of the plurality of arithmetic processing units and counts the number of the arithmetic processing units in the instruction processing stopped state, wherein the power control circuit of each of the plurality of arithmetic processing units disables the power save operation of the arithmetic processing unit in the instruction processing stopped state, in a case where the number of the arithmetic processing units in the instruction processing stopped state exceeds a threshold.
