The apparatus decodes an encoded video bit stream to produce pixel data of a first and second macroblocks. The video bit stream comprises at least one video packet, a first, second, third logic units. The first logic unit comprising parameters a1 and b1. The second logic unit comprises parameters a2 and b2. The third logic unit comprises parameters a3 and b3. The parameters a1 and a2 are used for reconstructing a first macroblock.

The searching module locates a first address indicating location of the first logic unit, a second address indicating location of the second logic unit, and a third address indicating location of the third logic unit. The decoding module first decodes the first logic unit to obtain a decoded parameter A1 corresponding to the parameter a1 without obtaining and storing a decoded parameter B1 corresponding to the parameter b1 into a memory. The decoding module also decodes the second/third logic unit to obtain a decoded parameter A2/A3 corresponding to the parameter a2/a3. Then, the decoded parameters A1, A2, and A3 are used to produce the pixel data of the first macroblock.

Abstract: The present invention provides an input data control method and system for a data processing system. The system comprises at least one basic operation unit (BOU) and is used for transforming one input matrix X into data in a plurality of specified columns in an output matrix Y via an inverse discrete cosine transform procedure. The method generates and outputs a transform control signal together with the input matrix to at least one of the BOUs. A new transform control signal is generated according to the received transform control signal, and outputted together with the input matrix X, to other following BOUs. The step of generating the new transform control signals is repeated until each specific column of the output matrix Y is decoded by a corresponding BOU. A basic operation procedure is then performed, and the received input matrix is decoded to obtain the data in the specified columns corresponding to the transform control signal.
