摘要
作为一种新型的高性能、热插拔和模块化测量仪器标准总线,PXI总线正广泛应用于测控领域和国防工业中.作者采用ARM微处理器双端口RAM CY7C025设计了基于PXI的智能化ARINC429总线通讯模块.该模块可进行复杂的计算处理,减少系统CPU的工作量,同时适应复杂的测控场合,能够满足较高的测控应用实时性要求.作者在文中详细介绍了PXI总线接口的设计、板载ARM微控制器的电路连接方法以及微控制器通过双口RAM和系统CPU之间的数据交换技术,对用于不同场合的各种智能总线扩展模块的设计都有一定的借鉴意义.
As a new type of the high performance, hot swap and modularization bus for instrumentatlon, PXI bus is widely used in many fields such as industrial automation and defense industry. In this paper, the design of intellective ARINC429 bus communication module using PXI technology is provided. This module can do sophisticated computation using ARM microcontroller to satisfy the real-time requirement of measure ＆ control applications. This paper minutely introduced periphery circuit connecting method of on-board microcontroller and data access technology through DPRAM between microcontroller and system CPU, is in some extent meaningful for the development of other kinds of intellectual bus extended module.
