PROBLEM TO BE SOLVED: To provide a data processing device in which plural processes can be executed simultaneously and at high speed. SOLUTION: Plural logic modules 30, 40, 50, and 60 each having only limited functions are connected to a data storage device 10 of a multiple port constitution. The data storage device 10 comprises plural data storage ranges for holding data, and plural reading ports and plural writing ports each having a limited address space. Each logic module 30, 40, 50, or 60 reads data from either of the plural data storage ranges through the reading ports in the data storage device 10. Prescribed processing is executed to the read data, and data expressing result of the processing are written in either of the plural data storage zone through the writing port in the data storage device 10.
