Abstract:The AXIe Base Architecture defines an extensible platform for general purpose, modular instrumentation. The architecture incorporates the best features of earlier modular open instrumentation platforms, including VXIbus, PXI, and LXI. Like VXIbus and PXI, the architecture is based on a popular modular computing platform with added features important to developers and users of test and measurement systems. It is introduced in this paper that AXIe 1.0 Base Architecture and AXIe 2.0 Base Software Specification and AXIe 3.1 Semiconductor Test Extension Specification. And the status quo and development trend of AXIe bus was discussed
