Abstract: An image forming apparatus and a method of acquiring a memory area are disclosed for preventing a problem that image data cannot be converted due to failure of memory acquisition. The image forming apparatus includes an image data conversion part, a resource management part and an image data management part. The image data conversion part has at least one conversion function to convert a format of image data. The resource management part determines a memory size required for a conversion function to convert the format of the image data. The image data management part acquires a memory area corresponding to the determined memory size.

Abstract: An image-forming apparatus with a hardware resource used for image formation, a program for performing processing related to the image formation, and a communication part includes a format information acquisition part, a format determination part, and an image data conversion part. The format information acquisition part acquires format information from an apparatus connected to the image-forming apparatus via the communication part. The format information includes information on a format of image data supportable by the connected apparatus. The format determination part determines the transfer-time format of image data to be transferred to the connected apparatus based on the acquired format information. The image data conversion part performs format conversion of the image data to be transferred to the connected apparatus in accordance with the determined transfer-time format of the image data.

Abstract: A data processing device is disclosed. The device is provided with a plurality of data processing units; a first memory shared for storing data, to which each of the data processing units makes an access so as to perform an operation; a transfer completion time designation unit for designating a transfer completion time according to need, within which transferring the data in response to the accesses made by the data processing units should be completed; an expected transfer completion time calculation unit for calculating an expected transfer completion time needed for completing the data transfer in response to the accesses made by the data processing units, taking current access status of the first memory into consideration; and an access management unit for managing the access to the first memory based on the transfer completion time and the expected transfer completion time.

Abstract: An apparatus for forming an image, in which hardware resources for use in the forming of the image are provided, and a program runs in respect of the forming of the image. The apparatus includes an image data converting unit which converts a format of image data, and a format unifying unit which unifies a plurality of formats of image data by utilizing the image data converting unit.

Abstract: An image forming apparatus comprises hardware resources provided for use in image formation, programs performing respective processing related to the image formation, an image-data transforming unit transforming source image data into destination image data, an image-data memory unit having a source area in which the source image data is stored and a destination area in which the destination image data is stored, and an image-data management unit storing the source image data into the image-data memory unit. The image forming apparatus is configured so that while the image-data transforming unit transforms a preceding source image data stored in the image-data memory unit, the image-data management unit stores a following source image, subsequently transformed by the image-data transforming unit, into the image-data memory unit.

Abstract: 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.

Abstract: 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.

Abstract: A first storage stores input image data. A second storage stores image data read from the first storage. A control part determines, with respect to a timing at which data transfer of image data into the first storage, a data transfer of the said image data from the first storage to the second storage, based on a rate of data transfer and writing of the image data into the first storage and rate of data transfer and writing of the image data into the second storage from the first storage.
