摘要
本文着重研究推出一种先进的纯实数离散余弦变换的快速算法，文中借助于流程图和算式详细介绍了该算法的推导过程，与传统的借助于ＦＦＴ实现的ＦＣＴ相比．该算法速度提高一倍以上、存贮空间节约一倍左右，为ＦＣＴ的硬件实现提供了一条更便利的途径．
This paper presents an advanced fast algorithm for the discrete cosinetransform,the process is described in detail with the aid of the flow graph and formulae,compared with the DCT algorithms that is realized with aid of FFT. This algorithmdoubles its speed and reduced the memories space by half. This algorithm prouides aneasier way for real-time im Plementatiom of DC.
