Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image forming device capable of using the resources of a mulfunctional compound unit to the maximum. SOLUTION: Each device is provided with a device driver for executing control, and DMA setting and data transfer is controlled in this driver. Also, an address space address is managed by a bus driver for controlling the whole bus. In this case, the DMA is set in each driver for each device, and the data size of the DMA transfer is limited to a fixed size for limiting a use ratio. The divided data transfer request is registered in the bus driver, and the whole data transfer is controlled in the bus driver. COPYRIGHT: (C)2004,JPO
