Abstract

Systems and methods of operating a memory controller may provide for receiving a write request from a motion compensation module wherein the write request includes video data. A compression of the video data may be conducted to obtain compressed data wherein the compression of the video data is transparent to the motion compensation module. In addition the compressed data can be stored to one or more memory chips. Moreover a read request may be received wherein stored data is retrieved from at least one of the one or more memory chips in response to the request. Additionally a decompression of the stored data may be conducted to obtain decompressed data.
