摘要
H.264是新一代视频编码标准,具有很好的视频压缩性能。H.264的DCT变换是一种4×4的整数变换,适用于专用集成电路的硬件实现。采用一种新颖的实现方法,利用4-2压缩器和超前进位加法器来代替传统的加法,提高了运算速度。
H.264 is the new generation of video coding standard which has good performance in data compression.H.264 DCT transformation is a 4×4 integer transformation,which is suitable for hardware implementation of using application specified integrated circuit.This paper proposes a new method,which uses the 4-2 compressor and CLA instead of the traditional adder to improve the transformation speed.
