摘要

To provide an information processing device for realizing the interpreter method emulation by using a processor having a performance requested for the compile method emulation. An information processing device is used which includes a host processor 1 for executing predetermined processing and a coprocessor 2 for executing emulation in accordance with a direction from the host processor 1. The coprocessor 2 determines whether the processing to be executed in accordance with emulation may be executed by the coprocessor 2 when execution of emulation is directed from the host processor 1. The coprocessor 2 executes the processing when the processing may be executed by the coprocessor 2 but leaves execution of the processing to the host processor 1 when the processing may not be executed.
