US Patent 7881546 Slab-based processing engine for motion video

Systems and methods of encoding a video signal that includes a succession of images are disclosed. A system may include a plurality of independently programmable processing elements (PEs), an input interface device adapted to receive, buffer, and divide the input video signal in a manner appropriate to the plurality of PEs, and an output interface device adapted to receive encoded bitstreams generated by the plurality of PEs and provide an encoded video signal. Each PE is configurable to carry out the steps of a selected encoding algorithm and includes a digital processor and a memory in communication with the digital processor. The memories are independently accessible, and PEs communicate with each another during the encoding.
