摘要
本文介绍了基于FPGA的出租车计价器系统的功能、设计思想和实现,该设计采用模块化自上而下的层次化设计,顶层设计有5个模块,各模块中子模块采用VHDL或图形法设计。在Max+plusⅡ下实现编译、仿真等,最后成功下载到FPGA芯片中。完成了可预置自动计费、自动计程、计时、空车显示等多功能计价器。由于FPGA具有高密度、可编程及有强大的软件支持等特点,所以该设计具有功能强、灵活和可靠性高等特点,具有一定的实用价值。
This paper introduces the function, design idea and realization of taximeter based on FPGA. The design takes the method of top-down and step by step. The whole system was divided into five modules that were described by VHDL or schematic diagram. By using Max＋plus l] accomplish the compiler, simulator and so on. And then it can be downloaded to the FPGA chip . Achieve the goal to make a taximeter with the function of automatism count the money, the kilometer, the time and show empty car on a screen, ether. On FPGA high density and Programmable ability, you can see it has function better, modify convenient and high dependability. It has certainly practical value.
