[Picture Viewer] Player+Demo+Source

Description: 本解码器类支持普通jpeg文件格式，这也是目前大多数jpeg文件所采用的格式，此格式主要特点是数据精度为8位，采用Huffman编码的普通DCT帧（不支持扩展串行和递进模式及数学编码）。本解码器类的IDCT算法采用三种模式，分别是浮点解码、定点整数解码和定点整数MMX优化解码，您可根据具体情况选择。-The decoder supports the general category jpeg file format, which is most used in jpeg file format is the main characteristics of data accuracy of eight, using Huffman coding common DCT frame (do not support the extension of serial and progressive mode and Mathematics encoding). This type of IDCT decoder algorithm uses three models, namely the floating-point decoding, fixed-point integer decoding and fixed-point integer MMX optimized decoder, you can choose according to specific circumstances.

[Other] MaseraConf_17.pdf.tar

Description: 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- multiplication scheme can be used to derive parallel architectures for 1-D integer DCT of different lengths. We also show that the proposed structure could be reusable for DCT of lengths 4, 8, 16, and 32 with a throughput of 32 DCT coefficients per cycle irrespective of the transform size. Moreover, the proposed architecture could be pruned to reduce the complexity of implementation substantially with only a marginal affect on the coding performance
