双通道数据传输PXI总线接口控制程序设计与实现

PXI总线是NI公司在计算机外设总线PCI的基础上实现的新一代仪器总线,已经成为业界开放式总线的标准。基于PXI总线的数字化仪器模块是现代测试系统中重要的一种数据记录与处理设备。本文将介绍一种基于PXI总线的双通道信号解调板的PXI总线实时性传局部总线应用提供了宝贵的经验。

Designment and Realization of the controller for Dual-channel data transfers based on PXI bus

PXI bus is a new generation of instrument bus develop on the basis of the PCI bus by NI company,which has become the open industry standard on bus.Digital instrument based PXI bus is an important data recording and processing equipment on modern test system.This article introduces a project about a real-time dual channel data transfers based on PXI bus,while using PXI local bus achieve synchronous clock data transfer to the adjacent slot,where the data finishes the decoding process.This can provides a valuable experience on multi-channel real-time transmission design and local bus applications on PXI bus.
