    摘要: An image processing apparatus is provided that includes a primary memory unit to buffer image data, a secondary memory unit to store the image data transferred from the primary memory unit, and a memory control unit that controls both memory units. The memory control unit transfers, if a plurality of items of image data are to be transferred, at least one of the items of image data divisionally from the primary memory unit to the secondary memory unit. When image data are transferred from the primary memory unit to the secondary memory unit, the memory control unit transfers a unit image either in a block or divisionally in multiple parts, and the memory control unit simultaneously transfers a plurality of images divisionally, the images being divided into varying numbers of parts so that each input and output of an image can evenly share the time of the secondary memory unit and a plurality of images can be efficiently transferred in parallel in a short time.

    摘要: In a data processing apparatus, an image memory has a descriptor region and an image region, the image region storing a plurality of blocks of image data, the descriptor region storing a corresponding number of descriptor information blocks for the plurality of image data blocks. A DMA controller controls DMA data transfer of the image data blocks from the image region according to each descriptor information block in the descriptor region. The DMA controller comprises a register which stores one of the descriptor information blocks from the descriptor region of the image memory, and a control unit which determines, at a time of occurrence of a CPU interrupt, a start timing of a DMA data output operation of the DMA controller during a DMA data input operation of the DMA controller when an image editing request contained in input image data is received, the CPU interrupt being caused to occur by an interrupt request bit of the descriptor information block read from the register.

    摘要: An image forming apparatus includes a plurality of memory devices, each including at least one image memory which stores image data. A controller controls input and output operations for the image data relative to the at least one image memory. An image reading device generates image data by scanning and reading an original document. At least one data input device inputs image data generated by an external source. A plurality of input paths transmit the image data generated by the image reading device and the image data input by the at least one data input device. An image memory switching device connects the plurality of input paths to the plurality of memory devices, receives the image data generated by the image reading device and the image data input by the at least one data input device, and switches the plurality of memory devices to transmit consecutive image data, which is consecutively sent through one of the plurality of input paths, to a same memory device among the plurality of memory devices when the image memory switching device receives the image data and the image data through the plurality of input paths.
