摘要
探讨一种基于可编程片上系统的嵌入式绞线式列车总线(WTB)网络控制节点机的研制方案。该方案采用FPGA作为核心器件,将Altera的NisoII软核处理器与WTB控制逻辑集成在单片FPGA内,取代了原来的工控节点机和控制部件相组成的方案。减小了产品的体积和重量,降低了硬件开发成本。该文给出了系统的总体设计方案,并分析了测试结果。
A kind of approach about a wire train bus network node computer based on SOPC is discussed. As the soft-core of the system, the NiosII soft-core processor and the WTB control logic are integrated on the single FPGA. The primary approach that the industrial control node computer and the control component are combined is replaced, It greatly speeds up the system and reduces the hardware cost. The whole design scheme of the system has been given. The result of test is analyzed,
