VXI总线寄存器基器件接口电路的设计

Design of the Interface Circuit Based on VXI Bus Register-based Device

在介绍ＶＸＩ总线寄存器基器件的接口原理基础上，提出了用地址修改码再寻址的方法，实现地址寻址方式、数据传输方式自适应切换．以数字 Ｉ／Ｏ模块为例，叙述用可编程芯片实现接口电路的思路及电路调试过程．

The interface theory of the VXI register-based device is introduced in this paper,for short, the address-refinding method by address-modifying code is also presented ,in which the finding-address method and the auto-adapting switch of the data transfer-method are achieved .With the practice of digital I/Q model, the approach of implementing the interface circuit with ISP chip is proposed in this paper, along with the process of adjusting the model.
