The design adopts EDA technology to achieve a remote data acquisition system. The system aims at the lack of data acquisition card which is high cost and easily be affected within PC environment, thus it uses Universal Serial Bus technology to collect the data. FPGA is adopted as the controller to control A/D converter and store and deal with the converted… (More)
This paper introduces the principle of frequency divider and circuit design based on VHDL¿Cwhich describes integer and half-integer frequency division and the decimal frequency division algorithms. It can achieve any number divider for base frequency. The generality of this design is good. It can be used into the design of diverse digital circuit systems.
