| Abstract: | This paper proposes an NURBS curve interpolation hardware platform based on ARM-FPGA embedded tech-nology to achieve the purpose of high-speed and high-accuracy motion control. The hardware structure is designed. Then, the cross clock domain problem between ARM and FPGA is solved by using R/W falling edge as synchronization signal. The ARM-FPGA embedded hardware platform is developed independently. The practical test shows that data transfer between ARM and FPGA is reliable, and the proposed architecture would effectively reduce the computational load of NURBS curve interpolation in one single processor. |
