摘要： This disclosure describes efficient memory fetching techniques that can improve data fetching during a motion compensation decoding process. The techniques propose several different memory fetching modes that may be very efficient in different scenarios of the motion compensation decoding process. In some embodiments, a motion compensator selects a particular memory fetch mode from a plurality of possible modes on a case-by-case basis for the memory fetches associated with a motion compensation decoding process of a macroblock. The techniques described herein may be particularly useful when fractional interpolation to sub-integer pixels is used in the inter-frame compression.

In one configuration, a wireless communication device compliant with the VC1-SMPTE standard (e.g., cellular phone, etc.) comprises a processor that is configured to execute instructions operative to reconstruct reference frames from a received video bitstream. A non-intensity-compensated copy of a reference frame of the bitstream is stored in a memory of the device and used for defining the displayable images and for on-the-fly generation of a stream of intensity-compensated pixels to perform motion compensation calculations for frames of the video bitstream.

The method may also include determining data storage information associated with the compressed video data units, and storing the data storage information in the memory. A system may have a video processing architecture designed to support the method.

摘要： The motion estimation techniques and video encoding device(s) described use a two dimensional pipeline to generate accurate motion estimation parameters for a current video block. The two dimensional pipeline uses previously calculated motion estimation parameters of relevant neighboring video blocks, including a preceding video block on a same row as the current video block, prior to the generation of the accurate motion vectors, motion vector predictors, and mode decision of the current video block The use of the two dimensional pipeline allows accurate motion vector prediction from neighboring video blocks previously not available, in the computation of motion vectors. Three engines may be used in the two dimensional pipeline, a fetch engine, an integer search engine and a fractional and spatial search engine. While the fetch engine and fraction and spatial search engine operate on one row, the integer search engine operates on another row.
