Abstract: A data processing system includes the data processing apparatuses formed with the VUPU architecture by combining a general-purpose data processing unit and a special-purpose data processing unit equipped with a data path unit for specialized data processing that is executed according to special-purpose instructions, and equipping the general-purpose data processing unit with a communication function for communicating with the general-purpose data processing unit in another data processing apparatus. In this invention, these data processing apparatuses are combined to form the system with plurality of specialized circuits, therefore, the data processing system in which parallel processing is performed by a plurality of specialized circuits can be provided economically and in a short time.

Abstract: A data processing system includes a general-purpose data processing unit (PU) including an instruction issuing unit that fetches and decodes an instruction in a program and issues the instruction and an execution unit that executes general-purpose processing according to a general-purpose instruction in the program; a special-purpose data processing unit (VU), including a data path unit for special-purpose data processing, that executes special-purpose data processing according to a special-purpose instruction in the program; and a first clock supply unit for stopping, based on a wait signal that is issued by the VU and shows that the PU is waiting for processing of the VU, a first clock signal for a part of the PU.
