The image forming apparatus includes: a part for sending order information to the office supply information server; and a part for receiving information from the office supply information server, the office supply information server includes: a server information sending part for sending information to the image forming apparatus; and a client information receiving part for receiving information input from the touch panel of the image forming apparatus, and the image forming apparatus orders an office supply from the office supply information server.
摘要:
A DRAM controller comprises an address output controller for transferring an address-designating signal to a dynamic RAM, a data output controller for transferring data to be written into and read-out from a memory region of the dynamic RAM which is designated by the address-designating signal, and a control circuit responsive to a mode-designating signal for generating various control signals corresponding to an access mode of the dynamic RAM designated by the mode-designating signal and for supplying control signals to the dynamic RAM, address output controller, and data output controller in a predetermined sequence. In the DRAM controller, the control circuit includes a signal-generating unit for generating control signals in a specific access mode which requires an access time longer than a machine cycle of a processor for generating the address-designating signal, the data to be written, and the mode-designating signal, the signal-generating means delaying generation control signals every time designation of the specific access mode by the mode-designating signal is repeated.
