The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

VHDL是Very High Speed Integrated Circuit Hardware Description Language的缩写， 意思是超高速集成电路硬件描述语言。对于复杂的数字系统的设计，它有独特的作用。它的硬件描述能力强，能轻易的描述出硬件的结构和功能。这种语言的应用至少意味着两种重大的改变：电路的设计竟然可以通过文字描述的方式完成；电子电路可以当作文件一样来存储。随着现代技术的发展，这种语言的效益与作用日益明显，每年均能够以超过30％的速度快速成长。 这次毕业设计的内容是在简要介绍了VHDL语言的一些基本语法和概念后，进一步应用VHDL，在MAX+plusII 的环境下设计一个电子钟，最后通过仿真出时序图实现预定功能。电子钟的时间显示用到了七段数码管(或称七段显示器)的电路设计，内部的时间控制输出则用到了各种设计，包括：加法计数器，扫描电路，控制秒、分、时的分频电路，各种数制的转换。
