摘要 2DDCT用于图象压缩标准,传统实现方法存在计算量大、结构不规则的缺点,需要系统资源较多。本文在DA算法的基础上提出了一种新的实现方法,结构规则,节省系统资源且能有效提高运算速度。 2DDCT architecture is used in most image and video systems.The traditional implementations have the disadvantages of comutation complexity and abnormality configuration and they demand more system resources.Based on the research of DA algorithm,this paper proposes a new method which has the advantage of regular configuration and demands less system resources.The computation speed can be improved obviously.
