Abstract: A data processing system of the invention comprises a special purpose data processing unit for executing a series of predetermined data processings by a special purpose instruction and a general purpose data processing unit for executing processings designated by general purpose instructions. The special purpose data processing unit has a dedicated circuit portion specialized in specific data processings and a sequence control portion that supplies the dedicated circuit portion with control signals to control the dedicated circuit portion in accordance with a predetermined processing procedure. In addition, the general purpose data processing unit can control the dedicated circuit portion in accordance with a procedure different from the processing procedure preset in the sequence control portion. Thus, it is possible to provide the data processing system that can flexibly deal with even such alterations as have an influence on the specification of the special purpose data processing unit.

Abstract: A data processing system is provided that includes a special purpose data processing unit (VU) specialized in a specific data processing according to a special purpose instruction, and a general purpose data processing unit (PU) capable of designating processes by general purpose instructions, and an instruction issue unit for supplying signals corresponding to the special purpose instruction and the general purpose instructions to the PU and the VU respectively, the instruction issue unit being an application-specific unit. By replacing the instruction issue unit with a sequencer specialized in the application, a reliable, compact, low-power consumption data processing system is provided in a short period using the resources resulting from optimization with the programmable VUPU processor capable of flexibly dealing with the specification change while maintaining the real-time response.
