Abstract
According to one embodiment, a circuit for generating motion compensated video includes a means for translating a macroblock into one or more motion compensation commands having associated correction data related to the macroblock. The motion compensation command is an autonomous command that supports a plurality of motion compensation modes. Also, the circuit includes a means for receiving the motion compensation command, a means for storing the correction data in a memory according to a first order corresponding to the motion compensation command and a means for performing frame prediction operations in response to the motion compensation command. Moreover, the circuit includes a means for reading the correction data from the memory according to a second order and a means for combining the correction data with results from the frame prediction operations to generate an output video frame.
