Abstract
An image processing module input/output port in a DMAC includes an input part which receives second address information and an addressing request signal from an image processing module and an output part which outputs a reply signal indicating valid reception of the second address information to the image processing module. The image processing module input/output port can perform signal input/output control processing of returning, in response to the addressing request signal, the reply signal indicating confirmation of valid reception of the second address information to the image processing module when valid reception of the second address information is confirmed. A memory access controller performs memory access processing of accessing a storage area to be accessed in a memory based on the first address information (=the second address information) received via the image processing module input/output port.
