PROBLEM TO BE SOLVED: To execute image processing without suspending image processing until all communication information are processed when sharing and storing the communication information and image information. SOLUTION: A transfer control part 40 uses a buffer 38 for communication and a buffer 4 for image processing as a buffer for network reception, and temporarily stores data received form a network 14 in the buffer 38 for communication, and a DMA control part 36 DMA transfers the data to the buffer 34 for image processing when there is no image processing request. On the other hand, when a CPU 16 recognizes an image processing request and determines that the buffer 34 for image processing is used, a transfer control part deletes packets stored in the buffer 34 for image formation. Then, an image processing part 26 starts image processing by the control of the CPU 16. COPYRIGHT: (C)2009,JPO&INPIT |
