CACHING APPARATUS AND METHOD FOR VIDEO MOTION ESTIMATION AND COMPENSATION

摘要

A caching apparatus for video motion estimation and compensation includes: an external memory including a plurality of banks and configured to allocate one pixel row to one bank to store the pixel row; a memory controller configured to cause successively-inputted read requests to access different banks of the external memory and transmit a read command for a next read request to the external memory while reference data corresponding to a first-coming read request is outputted; and a data processor configured to successively make read requests for the reference data to the memory controller when reference data read requests are successively inputted, store the reference data inputted from the memory controller, and output the stored reference data.
