H.264图像编码程序对输入像素块X的整数DCT变换和量化-H.264 encoding process the input image pixel block X integer DCT transform and quantization

In this paper, we present area- and power-efficient architectures for the implementation of integer discrete cosine transform (DCT) of different lengths to be used in High Efficiency Video Coding (HEVC). We show that an efficient constant matrix-
