Abstract
An arithmetic processing device includes arithmetic processing units, each having a calculator unit; a scheduler that controls a push instruction to write data to a register file in one of the arithmetic processing units and a pull instruction to read data from the register file; a pull request bus to which the scheduler outputs a pull request and which is connected to the arithmetic processing units; a push request bus to which the scheduler outputs a push request and which is connected to the arithmetic processing units; and a pull data bus that inputs, into the scheduler, pull data read from the register file in response to the pull request. Each of the arithmetic processing units includes a pull data turn-back bus that propagates pull data read from its register file to the pull data bus.
