实现了三种乘法器，可以进行性能比较，比较有较之

HDL编程风格，很有用,希望对大家有所帮助。-HDL programming style, very useful, we want to help.

用DE0开发板实现电话计费器，基本功能：可设置通话模式，能初始化话费余额，拨动开关可进入通话模式，并根据通话时间和相应通话模式扣除相应的费用。通话过程中能够通过开关切换显示通话时间和话费余额，并可暂停通话。压缩包里有详细的WORD文档的说明，包括波形仿真和DE0的引脚功能介绍。(Implemented by DE0 board telephone billing, basic function: to set the call mode, you can initiate credit balance, toggle switch into the talk mode, and deduct the cost of a call based on call time and the corresponding mode. Call talk time and can be displayed by switching credit balance, and mute. Compression bag has a detailed description of WORD documents, including the waveform simulation and DE0 pin function description.)
