基于FPGA的出租车计价系统设计

Design of taximeter based on FPGA

设计出租车计价系统,运用自顶向下的设计思想,以芯片CycloneⅡEP2C8T144C8为设计核心,采用QuartusⅡ仿真软件,对设计电路的各模块及整个系统进行了EDA仿真验证。结果表明,该计价系统具有计时、计费、计程和动态显示的功能,符合设计要求,修改VHDL语言源程序,可完成更多的出租车计价系统的扩展功能。

A taximeter based on Quartus Ⅱ simulation software was designed by using FPGA chip cyclone Ⅱ EP2C8T144C8,which is of top-down design idea.The circuit of each module and the entire system were simulated.The simulation results prove that the taximeter system is of counting time,billing,metering and dynamic display function.To modify the VHDL language source code,it can complete more taximeter extended functions.
