基于SOPC的电子点菜单设计VIP免费

摘要论文提出一种新型的电子点菜系统以弥补传统点菜方式的弊端。在目前的餐馆里，如果采用电子菜单，客人点菜时不需要服务员的陪伴，能实时地了解菜的特色，方便了顾客同时也减轻了餐馆的服务压力。本课题是基于SOPC的电子点菜单的设计，该电子点菜系统实现了一个电子点菜终端的部分功能，如：显示菜的单价、口味、已点数量和总价等。本设计采用行扫描法实现4*4键盘的扫描，并对按键进行消抖处理。利用行波进位加法器进行总价的结算，使用静态RAM存储数据。整个设计是在ALTERA公司的QUARTUS编程环境下进行，在FPGA芯片上得以实现，通过模拟仿真，最终下载在CYC-L2便携式实验系统运行实现。本课题完成的电子点菜单功能齐全，使用方便，可大大提高服务质量，并节省许多人力物力。在餐饮业具有较好的推广价值。关键字：电子菜单；FPGA；VHDLAbstractThethesisputsforwardakindofnewelectronicsmenusystemtomakeupmenuoftraditionmethod.Incurrentrestaurant,iftheadoptionelectricitysubmenu,theguestordersthemenudonotneedtheattendanttokeepcompanywith,canbeaverygoodunderstandingofthecharacteristicsoffood,conveniencethecustomeralsoeasedtheservicepressureoftherestaurant.ThistopicisadesignthatordersthemenuaccordingtotheSOPC,thatelectronicsmenupartsoffunctionsthatthemenusystemcarriesoutanelectronicstoorderthevegetablesterminal,suchas:Showtheuprice,tasteofthefoodandhavealreadyorderedquantityandtotalpriceetcs.Thisdesignadoptiongoestoscanthemethodtocarryout4*4keyboardstoscan,andcarryoneliminatetotrembletheprocessingtothekey.Theexploitationgoesthewavebalanceofaccountsthatentersanaddertocarryonthetotalprice,savingdataoftheusagestaticstateRAM.ThewholedesigncarriesonundertheQUARTUSplaitdistanceenvironmentofthecompanyofALTERA,cancarryoutonthechipofFPGA,reallypasstoimitatetoimitate,theenddownloadisintheCYC-L2thentheholdtypeexperimentsystemcirculatestherealization.Theelectronicsthatthistopiccompleteordersthemenufunctionwell-found,theusageconvenience,canraisetheservicequantityconsumedly,andsavemanymanpowermaterialresources.Havetocompareinthediningindustrygoodofexpansionvalue.Keyword:electricmenu;FPGA;VHDL目录1绪论.............................................................................................................................11.1任务的提出......................................................................................................11.2设计的目的和意义..........................................................................................12相关知识简介.............................................................................................................32.1开发工具..........................................................................................................32.2开发语言..........................................................................................................32.3开发环境..........................................................................................................33总体设计.....................................................................................................................63.1设计的总体结构描述......................................................................................63.2功能模块描述..................................................................................................63.2.1键盘模块.............................................................................................................73.2.2显示模块.................................................................
