摘要/Abstract

摘要： 针对非均匀有理B样条（Non-Uniform Rational B-Spline，NURBS）曲线高速高精加工过程中计算负载高的问题，提出基于ARM-FPGA嵌入式技术的NURBS曲线插补硬件平台，对硬件平台结构进行了设计，利用读写下降沿同步信号解决ARM与FPGA跨时钟域总线传输问题，自主开发了ARM-FPGA嵌入式硬件平台。该平台结构具有小型化、智能化特点，在硬件平台上经实际测试表明，ARM与FPGA之间数据传输稳定可靠，能有效降低单一处理器的计算负载。

Abstract: This paper proposes an NURBS curve interpolation hardware platform based on ARM-FPGA embedded technology 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.
