PERIPHERAL APPARATUS FOR IMAGE MEMORIES

摘要

The peripheral LSI appt. comprises a read data processing unit sending the data of a selected one among n pixels read from the DRAM blocks in parallel to an external image/graphics processor. A write data processing unit modifies the image data taken into it and writes the modified data into the DRAM blocks. A feedback data processing unit writes the image data now on displaying into the DRAM blocks after a desired processing again. A display data procesing unit sends the data read from the DRAM blocks to a monitor for display and to the external processor for the feedback processing. A control unit furnishes control signals to those processing units in response to instructions from the external processor.
