초록
$\textbullet$ A FPGA-based One-chip position controller with the PCI interface was developed. $\textbullet$ The peripherals of the existent controller can be implemented in one FPGA device. $\textbullet$ For this purpose, the high capacity FPGA device was used. $\textbullet$ PCI controller was merged into the position controller by using the PCI controller of core form. $\textbullet$ The developed position controller used only one FPGA device to achieve the required function. $\textbullet$ By doing this, the overall system can be simplified. $\textbullet$ The noise and power dissipation problems can be minimized and it has the advantage in the price.
