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

摘要

Use a H. of accumulation264 forward/reverse 4x4 2D integer transformer structures are that each clock pulses is arranged to calculate a pixel to produce 30 frames and execute integer transform by using a reduced number of component. One H.264 forward/reverse 4x4 2D integer transformers structures are by using ranks separation method execution integer transform and including processing elements (100), it is used to execute one-dimensional transform and processing elements (110) in the respective column of an input block, is used to execute one-dimensional transform on the corresponding row of input block. Integer transformer structure receives the pixel for every clock pulses and is performed simultaneously integer transform, therefore an input block, is used to wait necessary data before transform operation is not used. The multiplexer for output data for every clock pulses is used for an output stage.
