Abstract

A system (and a method) are disclosed for intelligently fetch one or multiple reference blocks from memory for each block to be motion compensated or motion estimated within a video processing system. The system includes a reference block configuration evaluation unit and a motion compensation memory fetching unit. The reference block configuration evaluation unit analyzes the reference block configuration of the block being motion compensated with a plurality of reference block configurations of its neighboring blocks. In response to a reference block configuration evaluation result, the reference block configuration evaluation unit decides the configuration of reference blocks to be fetched from a memory. The motion vector memory fetching unit fetches the number of reference blocks for motion compensation accordingly.

First claim

What is claimed is:

1. A method for memory access of motion compensation for a block of video data, comprising:
receiving a plurality of motion compensation references, a motion compensation reference including a motion vector of a reference block and a memory address of the reference block, the reference block associated with the block of video data being motion compensated;
comparing a first motion vector of a reference block of the block being motion compensated with a second…
