PXI Express平台中数据的流向，组成的组件包含了PXI Express机箱、PXI Express控制器及模块化仪器，包含数字化仪及波形发生器。以高速数字化仪为例，模拟信号被ADC采集转换成数字量数据后，会搬移到板载内存上暂存，接下来再经由总线控制器及PCI Express接口，传送到PXI Express控制器的系统内存上，做后续的计算及处理。若数据的流向目的地是存储设备，则会在未经任何处理计算的情况下，被直接搬移到存储装置，以维持高速、连续不断的数据记录。在PXI Express背板上，采用了PCIe switch使得系统得以扩展出更多槽位。由于不同的PXI Express机箱有不同的槽位型态，因此每个PCIe switch的绕线方式都不同，进而影响到数据传输效率。如模块化仪器-波形发生器，其数据流则以相反方向运行。

图一、PXI Express平台与模块化仪器整体架构简化图，显示PXI Express系统的数据记录传输的方向

接下来我们会讨论数据记录系统的每个环节及对于数据带宽的影响。

l 模块化仪器的板载内存

大约十多年前，高速的PCI数字化仪都需要配备大量的板载内存以暂存来自高速ADC的数据，主要原因是当时的PCI总线仅能提供约132MB/s的数据带宽(多数系统仅能达到约80MB/s)。PCI总线的带宽，无法满足于8位1GS/s或14位200MS/s的数字化仪所需要的数据带宽。为了要增加记录或采集时间，512MB、1GB或甚至4GB的板载内存就会被应用于数字化仪之上。目前虽然高速PCIe总线接口可提供数倍于PCI总线的带宽，但数字化仪通常还是会配备有大量的板载内存深度(大于100MB)，用于当作数据暂存，以避免CPU或DMA控制器过于忙碌而无法实时传输数据。举例来说，一个单通道8位500MS/s的数字化仪，在完全不将数据传回系统内存状况下，可以记录高达1秒的时间，若配备有2GB内存则可记录高达4秒。
