应用背景以太网交换机所使用的以太网控制专用芯片多具有SMI接口,以实现对芯片的控制。考虑到以太网交换机的节能趋势,使用ARM芯片s3c2440作为以太网专用芯片的主控器件,使用软硬结合的方法,设计并实现了单片机系统与SMI接口的通信,介绍了SMI接口的特征和时序,并以以太网控制芯片88E6097为例,给出了在ARM芯片s3c2440上用I/O实现SMI接口的硬件电路和相关程序。关键技术基于c语言的SMI接口模拟，88E6097交换芯片的寄存器读写访问，88E6097芯片VLAN技术。采用ARM芯片s3c2440基于Linux的操作系统，通过c语言编程模拟SMI接口，对88E6097交换芯片的寄存器进行读取、写等操作，以达到对88E6097交换芯片基于802.1Q的VLAN配置。

Mobile Media API概述在当前世面上存在着大量的不同媒体格式，并且还有许多新的媒体格式即将被建立。-Mobile Media API outlined in the current world level there are lots of different media formats, and there are many new media formats will soon be established.

CORBA交易服务的实现源码。目前已经将CORBA标准中的CosTransactions.dll，CosTSInteroperation.dll，CosTSPortability.dll转化为c++代码，用户只要实现里面的CORBA存根，就可以实现一个CORBA交易服务。-CORBA transaction services to achieve the source. Now to the CORBA standard CosTransactions.dll, CosTSInteroperation.dll, CosTSPortability.dll into c code, as long as users realize the CORBA stubs inside, we would achieve a CORBA transaction services.
