基于多核ARM的可重构LXI测试设备设计

借鉴合成仪器的设计理念,提出一种LXI总线标准的可重构便携测试设备设计.该设备以多核ARM处理器与大容量FPGA组成的软硬件在线可重配置结构,通过LVDS高速总线与紧凑通用测试功能模块通信,实现测试现场软硬件灵活编程配置,很好地解决了通用性、灵活性与小型化等相互制约矛盾的测试需求;采用Android操作系统,支持手机、平板电脑等智能终端通过无线网络进行操作,为现场配置和操作提供了更大的灵活性.

Design of Reconfigurable LXI Test Equipment Based on Multi-Core ARM

Referenced to the design concept of synthetic instrument(SI),a LXI bus standard reconfigurable portable test equipment is proposed,whose hardware and software online reconfigurable structure is consisted of multi-core ARM processor and large capacity FPGA.LVDS high-speed bus is chosen to implement the communication between the system and compact universal test function module.Software and hardware can be reconfigured flexibly by programming,which makes test requirements of mutually restricted contradiction about generality,flexibility and miniaturization,matched well in this design.This equipment is embedded with Android operating system,and can be operated through wireless networks by intelligent terminals,such as mobile phones and tablets,which provides more flexibility for configuration and operation.
