8×8矩阵高速DCT的硬件实现

Implementation of High Speed 8×8 Matrix DCT

离散余弦变换（ＤＣＴ）在语音及图象处理方面应用广泛，本文采用行列分离的ＤＣＴ 算法，用ＸＩＬＩＮＸ 公司的ＦＰＧＡ 芯片设计了一个实现该算法的硬件运算电路， 在设计中着力于提高它的运算速度并控制硬件的规模，

A design program for DCT(Discrete Cosine Transforms),implemented in a XILINX FPGA chip,was proposed in this paper.Improvements in algorithms and circuit structure have been made to make the system possess a high performance in calculation accuracy and operation speed.
