虚拟仪器技术使用最新领先的商用PC技术实现比独立的仪器价格更低廉、更快、更高性能的测量应用。现在,虚拟仪器技术又采用了PCI Express。该总线提供的更高的专用带宽有助于测试控制领域的更广泛的应用,特别是高速、高通道数应用。此外,PCI Express和PCI插槽都可以在PC上使用,并且在今后的十年中会继续共存,确保了在基于计算机的测试和控制系统的现有的投资。
● 性能——特别是在带宽方面,X1链路时带宽超过PCI的两倍,并且随着通路的增加带宽也线性增宽。 ● 简化I/O ——简化芯片到芯片和内部用户之间过多的总线访问,如AGP,PCI-X和Hublink。这一特性能降低设计的复杂性和系统实现的成本。 ● 层次式构架——PCI所建立的构架能在保护软件投资的同时采用新技术。层次式构架带来的两方面好处是提高信号速率的物理层和软件兼容性。 ● 新一代I/O ——通过同步数据传输,PCI Express 能为数据采集和多媒体应用提供新的功能。同步传输能提高服务质量(QOS)保证,从而确保数据以确定性和依赖时间的方式及时地传送。 ● 易用性——PCI Express 能极大地简化用户对系统进行添加和升级。PCI Express 支持热交换和热插拔。由于热插拔依赖于特定的操作系统特性,可能会延缓硬件的推出。
