PROBLEM TO BE SOLVED: To contribute to improvement in a speed of data transmission for a server administration, without increasing a load of normal operation. SOLUTION: It has a central processing unit (31), an external memory interface circuit (32), a network interface circuit (33), an image process part (23), and a data compression section (24). The image process part performs image processing corresponding to input from an external bus. The image process part is connected to the external memory interface circuit by a dedicated internals bus (37). The image process part stores an image data in an external memory through the dedicated internals bus. A compression section is connected to the image process part, and can compress the image data supplied from the image process part. Since the image process part receives image information and the dedicated internals bus which stores it in the external memory is separated from a common internals bus, the data of the image processing by the image process part which responds an instruction from outside does not compete on the common internal bus with the data for the data processing by the instruction from the network interface circuit.
