The Design of Software Programming for Taxi Price Calculation

摘要

In recent years, integrated circuit and its design and manufacturing tools have developed very rapidly. The appearance of Complex Programmable Logic Device and Field - Programmable Gate Array brought about great changes in electronic design technology. Because of short development cycles, low cost, high reliability, freedom to modify logic functions, FPGA programming are favored by engineers of Electronic Design Automation, and the demand for electronic product is also increasing. Current taxi meter with single-chip microcomputer system has poor stability, inflexible pricing mode easiness to be cracked and cheating, so designing a multifunctional taxi meter based on new technologies has practical and economic value. This paper introduced FPGA technology and carried on a series of improvements on the existing taximeter software and hardware based on VHDL language, and also developed some functions according to industrial applications and geographical characteristics.
