实时以太网核心调度模块设计及FPGA实现

摘要

随着我国军工科技在图像识别、人工智能、机器人技术和多传感器融合等一系列领域上均取得了先进的科研成果.这些科研成果的成功取决于网络的带宽和实时性是否满足传输要求.实时以太网技术以其高带宽、高可靠性、高实时性的特点,成为了取代其他总线网络的首要选择.实时以太网采用星型拓扑结构且拓扑结构中心是网络交换模块,网络交换模块核心是调度模块.运用FPGA技术实现核心调度模块,使实时网络在MAC层实现其存储转发的主要功能,进而提高网络实时性和可靠性,为实时以太网的在火控领域的应用打下坚实的基础.%With China's military technology in image recognition,intelligence,robot technology and multiple sensor fusion field are obtained,and a series of advanced scientific research achievements.The success of these research results depends on the bandwidth of the network and whether meet the real-time transmission.Real-time Ethernet technology with its high bandwidth,high reliability,high real-time performance characteristics,has become the primary choice instead of other bus networks.To use the FPGA technology to realize the core scheduling module to make real-time network in MAC layer realize the main functions of the store and forward,to improve network real-time and reliability,for the application of real-time Ethernet in the field of fire control to lay a solid foundation.
