PXIe-1065  18槽的机箱  提供高达 1 GB/s 的带宽

PXIe-1065 功能介绍

问题: PXIe-1065 有什么新的功能特性?

解答: PXIe-1065 是一个18槽的机箱，包括:

1个 PXI Express 控制器插槽

9个 PXI-1 槽

4个 PXI 混合插槽

3个 PXI Express 槽

1个 定时插槽

机箱各槽的传输速率不同. 以下是关于PXIe-1065可用的不同连接和桥路的描述

PXIe-1065  PXI Express 插槽通过指定的 x4 link 直接连接至控制器槽并可提供每槽(槽 7和8)高达 1GB/s 的带宽. 由于开销,芯片优化等原因, 这些槽实际上可以 提供大约800 MB/s 上行(输入板卡执行写内存操作)带宽和400 MB/s 下行带宽.

PXIe-1065  两个独立的PCI 总线段（Segment ）提供增强型的PCI 吞吐量(相比较是其他18槽机箱的两倍). PCI 总线段1 是一低延迟的 PCI 总线: PCI Express 通过 PCI 桥路直接与控制器槽相连.

PXI Express 槽通过连接 PCI Express Switch, 因此工用一条 x4 link, 提供高达 1 GB/s 的带宽. 同样, 用户实际能够得到这些槽的总计带宽大约为上行800 MB/s ，下行400 MB/s. 例如, 9 到14 槽的6块输入板卡能够同时达到约每块133 MB/s 的带宽.

Q: What are the new features of the PXIe-1065?

Answer: The PXIe-1065 is an 18-slot chassis that includes:

One PXI Express controller slot

9 PXI-1 slots

4 PXI hybrid slots

3 PXI Express slots

One timing slot

The transmission rate of each slot in the chassis varies. Below is a description of the different connections and Bridges available for the PXIe-1065

The PXIe-1065 PXI Express slot connects directly to the controller slot via the specified x4 link and provides up to 1GB/s bandwidth per slot (slots 7 and 8). Due to overhead, chip optimization, etc., these slots can actually provide about 800 MB/s uplink (input board to perform write memory operations) bandwidth and 400 MB/s downlink bandwidth.

The PXIe-1065 has two separate PCI bus segments that provide enhanced PCI throughput (twice that of the other 18-slot chassis in comparison). PCI Bus Segment 1 is a low-latency PCI bus: PCI Express connects directly to the controller slot via the PCI bridge.

The PXI Express slot uses an x4 link by connecting to the PCI Express Switch, providing up to 1 GB/s of bandwidth. Again, users can actually get a total bandwidth of about 800 MB/s upstream and 400 MB/s downstream for these slots. For example, six input boards with 9 to 14 slots can simultaneously reach a bandwidth of about 133 MB/s each.
