At the home page was mentioned that AXIe uses PCI express for data communication. All links are x4, so it means total bandwidthis about 2 Gb per second. In the future, there will be x16 links with higher bandwidth. This solution was approved by AXIe Consortium. External controller and the system module are connected by PCI express cable to control modules. Typically, system module functionality is built into chasis, so users can find PCIe connector on chasis. If users choose to deploy built-in controller, they just need to plug it into one of the AXIe slots. Most of the modules are PCIe-based, but LAN can be used for future cost reduction too. AXIe bus is called “local bus” because of its structure — it is a set of very short buses that connect from one slot to an adjacent slot, and no further. High data rates (40 Gb per second and 80 Gb per second when transfer over local bus) are provided by short path length and 62 differential pairs. The local bus does not depend on protocol, and can include timing as well as data signals.
Commonly AXIe systems operate with integrated traditional instrumentation or modular instruments like PXI in rack. On the picture above you can see how it can be extended with LXI, PXI, and GP-IB instruments. Controller can be built into AXIe or PXI chassis, despite the fact that on picture PC is shown.
In shown diagram controller interpret AXIe as PXI system. They both have the same numeration, identification and behavior, so the most of PXI software work with AXIe properly. Each module come with LabView or IVI drivers. AXIe systems can be easily deployed in Windows environments like LabView, Matlab, Visual Basic and the most of C’s. Moreover, AXIe system can be deployed in Linux. Manufacturers offer some software for special purposes with spectrum analysis, waveform analysis, or waveform and signal creation functionality and solutions for digital products like USB or PCI express analysis.
