| Abstract | A method for implementing a deblocking filter comprising the steps of (A) providing an input buffer storing an unfiltered video frame, (B) providing an output buffer configured to store a filtered video frame, (C) reading pixel values for a plurality of macroblocks from the input buffer into a working buffer, (D) sequentially processing the pixel values in the working buffer through a plurality of filter stages using an array of parallel processors, where each of the plurality of filter stages operates on a different set of pixel values in the working buffer and (E) writing pixel values from a final output region of the working buffer to a respective filter output region of the output buffer. |
