基于QNX的分布式异构仿真平台的实现

QNX作为嵌入式实时操作系统之一,它具有强实时、高可靠性、可剪裁、可配置、可扩充、可移植的特点,支持主流嵌入式处理器,目前主要应用在军事武器装备和航空航天领域.本文从航空电子系统对实时操作系统的要求出发,着重介绍了嵌入式实时操作系统QNX在PC104平台上的移植和配置网络连接通信技术,实现了基于QNX的分布式异构仿真平台,并通过实例验证了QNX的实时通信机制,建立了QNX在航空电子系统中应用的雏形,并给出了下一步工作的重点.

Distributed Emulation Platform Based on Embedded Real-Time Operator System QNX

Known as an embedded Real-Time operator system,QNX can be configured,cut,extended and transplanted.The most valuable trait of QNX is to have strong real time and credibility.It can also support most of processors that we often use in aviation or spaceflight domain.This article is written in need of aviation electronic system based on embedded Real-Time operator system,it introduces a method by which we can easily transplant the embedded Real-Time operator system QNX to PC104 embedded platform.After that we validate the real time correspondence mechanism,and establish the rudiment that the QNX be applied to aviation avionics system.
