DATA PROCESSOR AND DATA PROCESSING SYSTEM

PROBLEM TO BE SOLVED: To efficiently read data.SOLUTION: A data processor includes a plurality of image processing parts 10 each of which performs pipe line processing in which an NOP process corresponding to a stand-by time for data readout is arranged before a process of using data stored in the storage area of an assigned storage device 50 and after a process of generating and outputting an address showing the readout position of the data. In correspondence with each of those image processing parts 10, the data processor includes: an intermediate buffer 32; an address buffer 34; DMA control parts 33 for sequentially reading addresses written in the address buffer 34, for reading data from the storage device 50, and for writing the data in the intermediate buffer 32; and an image processing part I/F 31 for writing the address output from the image processing part 10 in the address buffer 34, and for transferring the data written in the intermediate buffer 32 to the image processing part 10. Furthermore, the data processor includes: an exclusive control part 40 for exclusively applying an access authority to the storage device 50 to each of the DMA control parts 33.
