ARCHITECTURE OF 4X4 2-D INVERSE TRANSFORM UNIT FOR H.264 USING ACCUMULATION METHOD

摘要

4x4 2 is used for the h. using an accumulativeOne framework of 264 d inverse transformation blocks is arranged to avoid the use of input block and manufactures the calculating of input bus width and execution on the basis of input continually by input is received. 4x4 2 is used for the h. using an accumulativeOne framework of 264 d inverse transformation blocks includes an input net, the first processer (100), a second process (110), a multiplexer and output network and a controller. It inputs net and does not have to input block, input data is necessary to calculating to wait, pixel is continuously successively received by input and use pixel in calculating. First processor calculates the continuous unit of a pilot process matrix and utilizes, and input block data are shifted from input net. Second processor calculates a final result matrix of consistent conversion by using the scheduling data of pilot process matrix. The multiplexer and output network of the consistent continuous unit of conversion export final result matrix.
