基于VHDL的三维位移测控系统设计

Design of the 3-D displacement-measuring system based on VHDL

为解决以单片机为控制核心的测量系统可靠性低速度不高的问题 ,阐述了利用可编程逻辑器件CPLD作为控制处理器件的三维位移测控系统的设计思想 ,以及基于VHDL硬件描述语言开发该CPLD器件的设计流程和方法 .

The paper introduces a design idea of 3-D displacement-measuring system that uses programmable logic device CPLD as the control-processor to solve the problems of low dependability and slow speed of measuring system when using SCM as the central device, The design method of developing this CPLD based on Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) is also introduced in the paper.
