To contribute to increase data transmission rate for server management without increasing load during normal operation. A semiconductor integrated circuit includes: a central processing unit; an external memory interface circuit; a network interface circuit; an image processing unit; and a data compression unit. The image processing unit performs image processing in response to an input from an external bus, the image processing unit is coupled to an external memory interface circuit through a dedicated internal bus, and the image processing unit stores an image data into an external memory via the dedicated internal bus. The compression unit is coupled to the image processing unit and is capable of compressing the image data supplied from the image processing unit. Since the dedicated internal bus, through which the image processing unit receives image information and stores the same into the external memory, is separated from the common internal bus, the data for image processing by the image processing unit that responds to an instruction from the outside will not conflict with the data for data processing by an instruction from the network interface circuit on the common internal bus.
