A VUPU processor that is equipped with a special-purpose processing unit VU and a general-purpose processing unit PU is highly flexible and executes processing at high speed. In addition, in this invention, cooperative instructions that specify cooperative processing by the VU and the PU are introduced. When a fetched instruction is a cooperative instruction, the decode stage instruction is supplied to the VU and PU. The cooperative instruction can make the resources of the PU available to the VU, so that the resources of the PU can be used by the VU with effectively no overheads being required by the transfer of data between the VU and PU, so that an extremely flexible, high-speed processor is achieved.
