The host processor sets a program counter value indicating a storage destination of the subprocessor program and a processing start command for, the processing of the subprocessor to the register unit. The command fetch unit fetches a command designated by the program counter value, the command decoding unit decodes the command, and the operation unit performs command execution processing.
