基于Verilog HDL出租车计费系统的研制

Design of Taxi Accounting System Based on Verilog HDL

以上海地区的出租车计费器为例,利用VerilogHDL语言设计了出租车计费器,使其具有时间显示、计费以及模拟出租车启动、停止、复位等功能,并设置了动态扫描电路显示车费和对应时间,显示了硬件描述语言Verilog-HDL设计数字逻辑电路的优越性。源程序经MAX+PLUS 软件调试、优化,下载到EPF10K10TC144-3芯片中,可应用于实际的出租车收费系统。

The taxi accounting system referred to that used in Shanghai was designed by Verilog HDL, with functions of time display, account, and simulation of start, stop, pause and so on. In addition, the dynamic scanning circuit was designed to display the tariff number. The design of this system shows the advantage of Verilog HDL as a hardware description language. After debugging and optimizing the source program by the software MAX+PLUSⅡ of Altera Company, the program can be used in the real taxi accounting system by downloading to the EPK10K10TC144-3 chip.
