DRAM COMPRESSION SCHEME TO REDUCE POWER CONSUMPTION IN MOTION COMPENSATION AND DISPLAY REFRESH Russian patent published in 2016 - IPC G06F13/16 H04N19/426 

FIELD: computer engineering.

SUBSTANCE: computer-implemented method of operating a memory controller, comprising a compression module, in compression module receives a write request from a motion compensation module, wherein write request contains video data and is received by memory controller both directly and indirectly from said motion compensation module; conducting, by means of compression module, compression of video data to obtain compressed data, wherein compression of video data is transparent to motion compensation module; storing compressed data in one or more memory chips; receiving, by a decompression module, a read request, wherein said read request is transmitted both directly and indirectly from motion compensation module or display device; retrieving, by decompression module, stored data from at least of one or more memory chips in response to read request; and performing, by decompression module, decompression of stored data to obtain decompressed data.

EFFECT: reduced power consumption due to more efficient access to buffer frames.
