出租车计价系统的FPGA设计

FPGA Design of the Taximeter

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Altera FPGA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, the importance of taximeter in our life is introduced. Accading to the design require and principle, design a real taximeter system based on Altera FPGA used the VHDL language. The circuit structure and program are introduced in this paper too. And give the design result and the simulating wave in QuarmsII5.0 software. The system has the function of the taximeter which is used in our life. If make further improvement on its function, it can be put into market.
