Abstract
The architecture shown can perform global search, local search and local sub pixel search in a parallel or in a pipelined mode. All operations are in a streaming mode without the requirement of external intermediate data storage.
Claims7
An apparatus for motion estimation comprising of:
- a predictor engine connected to a vector SAD engine and a subpel engine;
- a vector SAD (Sum of Absolute Difference) engine connected to said subpel engine and said predictor engine;
- a subpel (sub pixel) engine connected to said vector SAD engine, said predictor engine ant to an interpolation reference buffer;
- a skip engine connected to a skip input buffer and a, MB (Macro Block) buffer;
- and
- a plurality of local buffers.
