| Abstract: | This paper introduces a design of multifunctional interface card based on PC104 and FPGA. The design of this card accords with PC104 bus standard, and uses FPGA as kernel component. Except several interface ports, most of the logic circuits are integrated in one chip of FPGA, which can simplify the hardware circuit. As a result, the interface card can generate high- precision pulse signals and can be used in detection of quadrature encoder pulse(QEP) signal. |
