This system's 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, realiz...
