基于PC的开放式数控系统I/O卡数据传输接口设计
|
摘要
在PC+可编程IO卡体系结构下开发基于Linux的软件型开放式数控系统,围绕高速、高精、大数据量处理的要求,通过PCI Express总线实现PC与可编程I/O卡之间的数据传输。针对可编程I/O卡上数据传输结构分析所需处理的总线事务,在可编程I/O卡上采用模块化设计方法设计数据传输接口模块。仿真和实验结果显示,所设计的数据传输接口较好地实现了软硬件之间数据的通信。
Under the PC+programmable IO card architecture,around the requirements of high-speed,high-precision,and large-volume data processing,develop a open soft CNC system based on Linux,data communication between the PC and the programmable I/O card is achieved through the PCI Express bus.By analyzing the data transfer structure on the programmable I/O card and the bus transaction that the data transfer interface module needs to process,data transmission interface of programmable I/O card is designed through a modular design method.Simulation and experimental results show that data communication between hardware and software is well achieved.
