基于fpga的出租车计价器的设计—学士学位论文.docVIP

论文题目：基于FPGA的出租车计价器的设计 专 业：微电子科学与工程 摘 要 出租车计价器是乘客与司机双方的交易准则。具有良好性能的计价器无论是对广大出租车司机朋友还是乘客来说都是很必要的。现在各大中城市出租车行业都已普及自动计价器，而部分小城市尚未普及，但随着城市建设日益加快，象征着城市面貌的出租车行业也将加速发展，所以计价器的普及也是毫无疑问的。 本论文阐述了EDA的发展及其优势发展趋势结构特点和各以及。的 关键字 FPGA，VHDL，Quartus II，出租车计价器 Subject: The design of the taxi meter based on FPGA Specialty: Microeletronics Science and Engineering Name:Dan Shen (Signature) ___________ Instructor: Gaili Yue (Signature) ___________ ABSTRACT Taxi meter is the rule of passenger and driver. Have a good performance of the meter for our taxi driver or passenger is very necessary. Now the automatic taxi meter has popularized, and some small city has not been popular, but with the quickening of city construction, the symbol of the city will accelerate development of the taxi industry. This article elaborates the concept and development of EDA , the development trend and structure of the FPGA, andexplains the advantages and grammar structure of VHDL ,meanwhile, analysed the function request, the basic principle as well as the method ofaccomplishment of each parts. This systems design programmes in the VHDL, compiled and emulated basing on Quartus II platform of Altera consists of four modules, that is speed, mileage, timing and billing module. This paper introduce one method that can use a chip of FPGA to design taxi meter, which consists of four modules, that is speed, mileage, timing and billing module, and then, describe the design of each module and give out the simulation. This taxi meter can be self-charging according to mileage, which also can simulate the state of speed,such as start, stop, and pause, at the same time, its reliability and commonality also can be improved. This design FPGA test box on running well, realize the different functions of the message accounting device.
