System and method for motion vector extraction and computation meeting 2-frame store and letterboxing requirements

A system for motion vector extraction and computation comprising:

• an architecture adapted to overlap an image extraction process with a computation process and to provide 2-frame store decode with letter box scaling capability, to extract a plurality of parameters usable for calculating a motion vector, and to compute motion vectors;
• said architecture being adapted to compute vertical and horizontal components of motion vectors in back to back cycles;
• and
• said architecture comprising a motion vector compute pipeline, wherein said overlap allows (i) said image extraction process to operate on a first block of data and (ii) said computation process to simultaneously operate on a second block of data.
