Abstract

AXIe computer-on-module based on COM Express, which involves embedded controllers for automated test systems. It solves the problems of complex design, poor scalability and high replacement cost in the current AXIe controller. In the AXIe computer module based on COM Express, the AXIe computer module provides a computer interface module to the controller backplane through a standard connector, and the AXIe computer module provides a PCIe link to the controller backplane, and the PCIe link is controlled by the AXIe computer module CPU PCIe controllers are provided. The COM Express-based AXIe computer module proposed by the present invention can realize the backplane interface defined by the AXIe specification, and can provide abundant general-purpose computer interface resources for users to use. Plug the computer module into the AXIe controller backplane and it can be used normally. Modular design can reduce design difficulty, reduce repeated design, and facilitate product replacement.

Description

technical field [0001] The invention relates to an embedded controller of an automatic test system, in particular to a modular embedded system of an AXIe test system. Background technique [0002] With the increasing requirements for the performance of automatic test systems and automatic test equipment, AXIe (Advanced TCA extensions for instrumentation and test, the extension of advanced telecommunication computing architecture in the field of instrumentation and testing) automatic test system architecture was proposed and gradually applied to the field of test and measurement. [0003] AXIe is an automatic test system architecture proposed by Agilent Technologies Co., Ltd. (Agilent). It is the latest test system architecture specification following VXI, PXI, and LXI. It fully draws on the experience of existing excellent test platform standards and integrates many advantages of traditional open and modular instrument test platforms. As the main reference specification of ...
