嵌入式CORBA模型的研究

The Research of Embedded CORBA Model

1 引言嵌入式计算机系统(下称嵌入式系统)是实时系统的重要组成部分,其结构紧凑、资源有限,一般由嵌入式微处理器等硬件及其软件(包括实时操作系统RTOS和实时应用程序)组成,具有嵌入性和实时性等特点。它通常以SOC(system on chip)、单片机、单板机、多板式箱体结构、嵌入式PC等形式嵌入到各式各样的设备或大系统(如数字移动电话、路由器、导弹)

Embedded system increasingly demands interoperability across heterogeneous platforms, it becomes necessary to introduce CORBA model into embedded system. This paper first presents the Embedded CORBA model,then analyzes the limitation of Real-time CORBA specifications ,last emphasizes the structure of Embedded CORBA model and its three main implementation manners.
