    摘要: An image forming apparatus receives raster image data transferred from an external device and forms an image on the basis of the received raster image data. The apparatus includes a processor that controls a transfer of the raster image data from the external device, a first memory connected to the processor through a first bus is used as a working area of the processor, a second memory that stores the raster image data, a memory control unit connected to the second memory through a second bus controls an operation of writing and reading the raster image data in and from the second memory, a printer engine that forms an image on the basis of the raster image data, and an engine control unit that reads the raster image data from the second memory through the memory control unit and supplies the printer engine with the read raster image data.

    摘要: A communication apparatus for carrying out communications to and from an external apparatus that includes a first interconnecting unit and a first non-transparent port and effects an interconnection for communications via the first non-transparent port is provided. The communication apparatus includes a second interconnecting unit that includes a second non-transparent port communicably connected to the first non-transparent port. The second interconnecting unit effects an interconnection for communications via the second non-transparent port. The second interconnecting unit performs, when the communication apparatus carries out communications to and from the external apparatus, address translation between an address for use by the communication apparatus and an address for use by the second non-transparent port.

    摘要: An image forming apparatus includes an image input device that reads an image to obtain image data and a printer engine that forms an image on a medium based on image data. A bus of a PCI Express standard is used to transfer data. Storage areas serving as end points of the standard and hardware resources that transmit data and receive image data to and from the storage areas are connected to an identical switch according to the PCI Express standard. Specifically, an input/output area, an image input device, and a printer engine are connected to one switch, and a storage area, a compressor, and a hard disk is connected to another switch.
