出租车计价器的VHDL设计 - 副本

毕业论文（设计）题目：出租车计价器的VHDL设计系部名称：信息工程系专业班级：自动083班学生姓名：XXX学号：2008XXXXXXXX指导教师：王老师教师职称：讲师2012年05月15日中原工学院信息商务学院毕业论文（设计）II摘要本文设计了一个出租车计价器系统，根据预定的设计要求和设计思路，以QuartusⅡ9.0软件为平台，使用VHDL硬件描述语言来实现本设计。本文的主要内容是设计系统的电路结构，编写VHDL程序和仿真实现设计要求。通过一系列模块的设计最后使本设计不仅能实现出租车的计费和预置以及模拟汽车启动、停止、暂停等功能，而且还能够动态扫描显示车费数目。通过仿真模拟，得到了设计结果以及在QuartusⅡ9.0软件下的仿真波形。经过对软件仿真波形和硬件调试结果的分析，可以发现本文设计的出租车计价系统具有实用出租车计价器的基本功能，能够完成模拟计费及相关任务，如能进一步的改进，在一定范围内是可以实用化和市场化的。关键字：出租车计价器QuartusⅡ9.0VHDL中原工学院信息商务学院毕业论文（设计）IIITheTaximetertheVHDLdesignAbstractThispaperdesignsataximetersystem,accordingtothepredetermineddesignrequirementsanddesignideas,inordertoQuartusⅡ9.0softwarefortheplatform,theuseofVHDLlanguagetorealizethehardwaredescriptionofthisdesign.themaincontentofthisarticleistodesignthesystemofthecircuitstructure,writeVHDLproceduresandsimulationdesignrequirements.throughaseriesofmoduledesignfinallymakethisdesigncannotonlyrealizethebillingandpresetandtaxicarstartandstop,simulationsuspended,andotherfunctions,butalsocoulddynamicallyscanshowedthatthenumberofthefare.throughthesimulation,thedesignresults,andgotinQuartusii9.0Ⅱsoftwaresimulationwaveform.afterthesoftwaresimulationwaveformandhardwaredebuggingtheresultanalysisofthedesigncanbefoundinthispaperthetaxivaluationsystemhaspracticalthebasicfunctionofthemetertaxi,canperformsimulationbillingandrelatedtasks,suchastofurtherimprovement,withinacertainrangecanbepracticalandmarket.Keywords：MetertaxiQuartusⅡ9.0VHDL中原工学院信息商务学院毕业论文（设计）IV目录1绪论..........................................................................................................................................11.1课题的现状....................................................................................................................11.2研究的目的和意义........................................................................................................21.3EDA系统框架结构........................................................................................................21.4硬件描述语言.................................................................................................................31.5VHDL的优点.................................................................................................................42出租车计价器的设计内容及方案论证................................................................................52.1基本设计要求................................................................................................................52.1.1计费功能......................................................................................................................52.1.2显示功能......................................................................................................................52.2基本设计思想................................................................................................................52.3三种设计方案比较........................................................................................................73基于VHDL的出租车计费系统的实现.................................................................................93.1VHDL的相关介绍..........................................................................................................93.1.1FPGA简介..................................................................................................................93.2系统模块设计................................................................................................................93.2.1lucheng模块................................................................................................................93.2.2jijia模块......................................................................................................................93.2.3zhongjia模块.............................................................................................................103.2.4jinzhi模块..................................................................................................................103.2.5xuantong模块............................................................................................................113.2.6se模块.......................................................................................................................113.2.7yima模块...................................................................................................................113.2.8miaocp模块...............................................................................................................124系统仿真................................................................................................................................134.1软件Quartusii9.0介绍.................................................................................................134.1.1软件功能介绍............................................................................................................134.1.2可编程逻辑器件设计流程简介................................................................................134.1.3MAX+plus可编程设计流程....................................................................................134.1.4项目编译（设计处理）................
