摘　　要：阐述了基于矩的离散余弦变换算法和易于VLSI实现的脉动阵列算法结构 ,然后从软硬件结构划分、电路实现技术等方面探讨离散余弦变换处理机系统的设计思路。最后给出用矩实现的计算框图、电路实现框图以及外围驱动软件的结构设计。In this paper, an algorithm of discrete cosine transform (DCT) via moment and its systolic array architecture is expounded, which is easily implemented with VLSI. And then, the design thought of DCT processor system about hardware\|software partition and technologies of circuit implementation is explored. Finally, a diagram of computing moment\|based DCT and circuit implementation principle and architecture design of outside driver software is presented.
