介绍了出租车计价器系统在实际生产生活中的重要性。根据预定的设计要求和设计思路,使用VHDL硬件描述

语言设计了一个实际的基于AlteraFPGA芯片的出租车计价系统,介绍了该系统的电路结构和程序设计。通过实验模拟,

得到了关键的设计结果和在QuartusII5.0软件下的仿真波形。经分析软件仿真的波形和硬件调试结果,证明该出租车计

价系统具有实用出租车计价器的基本功能,如能进一步完善,将可以实用化和市场化。-In this paper, theimportanceof taximeter inour lifeisintroduced. Accordingtothedesign requireand principle, designareal
