基于PCI总线的LXI B类接口模块设计

Design of Interface Module for LXI Class B Based on PCI

摘要:

介绍了在LXI C类接口模块的基础上,设计的基于PCI总线的LXI B类接口模块。重点解决了基于IEEE1588协议的LXI精密时钟同步技术。在模块设计中采用了FPGA对时间信息加盖时戳和直接获取网络数据包的方法,以提高系统的定时精度。该模块可以与传统仪器组合,构成低成本、高性能的LXI仪器。

Abstract:

The technique used in LXI class B device is the importance of this paper. In order to improve the precision of clock synchronization, FPGA was used in the system to stamp time label for the data on network. Using this module, a traditional instrument can be upgraded into a LXI instrument that is low cost and high-powered.
