    摘要: A peripheral apparatus for image memories can communicate image data with a memory assembly composed on n blocks (60-63) of a standard-type DRAM, whether DRAM is of page mode or of nibble mode. The apparatus comprises a read data processing unit (82) sending the data of selected one among n pixels read from the DRAM blocks in parallel to an external image/graphics processor (2), a write data processing unit (84) modifying the image data taken thereinto and writing the modified data in the DRAM blocks, a feedback data (86) processing unit writing the image data now on displaying into the DRAM blocks after a desired processing again, a display data processing unit (88) sending the data read from the DRAM blocks to a monitor for display and to the external processor (2) for the feedback processing, and a control unit (80) furnishing control signals to those processing units in response to instructions from the external processor.

    摘要: A high speed, multi-function and expandable image processing LSI (image signal processor) for realizing density image processing technique has been developed.
    An architecture of the image signal processor (ISP) which can process a density image having 256 tones at a video rate (256 x 256 image, 6MHz, non-interlace), allows expansion of a partial operation area (kernel) and can carry out various partial neighbourhood operation, is disclosed.
    The image signal processor (ISP) is a partial parallel type image processing LSI which carries out a parallel operation by using the same number of processor elements (PE's) as that of input pixel data used to produce one output pixel data.
