Abstract: The hardware design and implementation of a data acquisition module for 8 channel voltage-to-frequency conversion (VFC) signals are described. This module is mainly comprised of a counting-buffering unit, a FIFO RAM, a RS232C serial communication port and a control unit. The module is implemented in a single chip Xilinx field programmable gate array (FPGA). With Xilinx FPGA, the benefits from the design such as short time to market, high reliability and compactness for the whole system can be obtained.
