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.
