AC parallelization circuit, AC parallelization method, and parallel information processing device

摘要

An AC parallelization circuit includes a transmitting circuit configured to transmit a stop signal to instruct a device for executing calculation in an iteration immediately preceding an iteration for which a concerned device is responsible to stop the calculation in loop-carried dependency calculation; and an estimating circuit configured to generate, as a result of executing the calculation in the preceding iteration, an estimated value to be provided to an arithmetic circuit when the transmitting circuit transmits the stop signal.
