说明：  该文件是关于模拟退火算法的源程序文件，带有测试函数，可以直接使用.(This file is about simulated annealing algorithm source program file, with test function, can be used directly)

本文先介绍了整个系统的硬件电路设计，而后用VHDL硬件描述语言完成了系统控制程序的编写，并对系统进行了程序仿真及调试验证。本文特别详细的讨论了系统程序的编写，因为他关系到整个系统的功能实现，也是本设计的重点所在。设计中选用Protel 99se作为电路图编辑软件，选用Max+plusⅡ作为仿真环境。(This article first describes the overall system hardware design, then use the VHDL hardware description language, the system control program to complete the preparation, and system simulation and debugging of program verification. This particular system is discussed in detail the preparation process, because he related to the functions of the entire system to achieve, is the focus of this design. Design selected Protel 99se as circuit editing software, use Max+ plus Ⅱ as a simulation environment.)
