说明：  本章的目的是想通过对数字信号处理、计算（Computing）、算法和数据结构、编程语言和 程序、体系结构和硬线逻辑等基本概念的介绍，了解算法与硬线逻辑之间的关系从而引入 利用Verilog HDL 硬件描述语言设计复杂的数字逻辑系统的概念和方法。向读者展示一种 九十年代才真正开始在美国等先进的工业国家逐步推广的数字逻辑系统的设计方法
(Purpose of this chapter is to through digital signal processing, computing (Computing), algorithms and data structures, programming languages and programs, the logical architecture and hard-line description of the basic concepts to understand the algorithm and the relationship between hard-line logical to introduce using hardware description language Verilog HDL design complex digital logic concepts and methods. Nineties to show the reader a kind of really started in the United States and other advanced industrial countries to gradually extend the number of logic system design)
