基于QNX的CPCI板卡通信测试系统设计与实现

摘要

以PC104工控机为处理平台,探讨了基于此平台之上的板卡通信测试系统的设计.软件选用QNX实时操作系统,硬件上结合了CPCI总线技术,设计并实现了性能良好的测试系统,该设计方法为实时系统下的各种总线标准板卡间通信实现提供了一定的借鉴.%This paper explores the design of communication test system based on the PC104 IPC processing platform.As for software,the popular QNX real-time operating system is used;as for hardware,the CPCI bus technology is used.Through fully using the greatest potential of both aspects,the test system with good performance is successfully designed and implemented.In addition,under the real-time system the methods described in this paper are also to provide reference for a variety of bus standards to achieve communication between the boards.
