摘要
A deblocking filter includes a current macroblock buffer memory configured to store video data of a current macroblock to be filtered, a side macroblock buffer memory configured to store a portion of video data of neighboring macroblocks located on the side of the current macroblock, a register buffer array configured to store video data read from the current macroblock buffer memory for current filtering, video data read from the side macroblock buffer memory, and data of neighboring macroblocks, and an edge filter that is connected to the register buffer array and is configured to perform horizontal or vertical filtering on an edge of a subblock of the current macroblock of video data and to perform the other of horizontal or vertical filtering on an edge of a subsequent subblock of the current macroblock of the video data, simultaneously. Vertical filtering uses the data from the neighboring macroblocks and horizontal filtering uses the video data from the side macroblock buffer memory.
