Optimized motion compensation and motion estimation for video coding

A system for optimizing memory access of motion compensation for a block of video data which is one of a plurality of blocks of a picture of video data, comprising:

• a receiving module for receiving a plurality of motion compensation references, a motion compensation reference including at least a motion vector of the block being motion compensated and a memory address of a reference block which is associated with the block being motion compensated;
• a reference block configuration evaluation unit for evaluating reference block configurations of the plurality of motion compensation references, wherein evaluating reference block configurations of the plurality of motion compensation references comprises comparing the configuration of a reference block of the block being motion compensated with the configuration of a reference block of a neighboring block of the block being motion compensated;
• and
• a motion compensation memory fetching unit for determining the configuration of reference blocks to be fetched from a memory collectively responsive to an evaluation result.

A computer program product for optimizing memory access of motion compensation for a block of video data which is one of a plurality of blocks of a picture of video data, the computer program product comprising a non-transitory computer-readable medium containing computer program code for:

• receiving a plurality of motion compensation references, a motion compensation reference including at least a motion vector of the block being motion compensated and a memory address of a reference block which is associated with the block being motion compensated;
• evaluating reference block configurations of the plurality of motion compensation references, wherein evaluating reference block configurations of the plurality of motion compensation references comprises comparing the configuration of a reference block of the block being motion compensated with the configuration of a reference block of a neighboring block of the block being motion compensated;
• and
• determining the configuration of reference blocks to be fetched from a memory collectively responsive to an evaluation result.
