A system for selectively handling information. In an example embodiment, the system includes a first mechanism for processing information pertaining to one or more sub-blocks of a macroblock in a first stream and a second stream, and outputting a first processed stream and a second processed stream in response thereto. A second mechanism selectively combines information in the first processed stream and the second processed stream and provides an updated version of the first stream or the second stream to the first mechanism in response thereto. In a more specific embodiment, the first mechanism includes a processor, such as in intra 4×4 search, module, that processes a sub-block of a macroblock by performing intra prediction for the sub-block. The processor is adapted to process sub-blocks of a macroblock in parallel, such as in a pipelined fashion or via separate engines capable of operating in parallel. |
