PROBLEM TO BE SOLVED: To provide a processor capable of processing the contact for the usability of a memory region from a coprocessor at high speed. SOLUTION: When a command decode/condition execution determination circuit 12 determines that the decoded command is a prescribed command during the operation of a slave processor 3, it interrupts the execution of this command by a command execution unit 2. When the operation of the slave processor 3 is ended, the command decode/condition execution determination circuit 12 restarts the execution of the command by the command execution unit 2. Accordingly, the synchronization with the slave processor 3 can be attained without starting an interruption handler, and the processing can be performed at high speed.
