Research Of Embedded Operating System That Supports AOS

This thesis is based on the use of RTOS in AOS, focus on the application of Real Time Embedded Operating System that will meet the need of AOS.In this paper we have researched mainly Real Time Embedded Operating System, including the develop process of BSP for Embedded Operating System, the cutting-down of RTOS, the RTNP model in AOS, and the implement of Internet Service for AOS, in detailed as follows:(1) Give the main property of Embedded Operating System, comparethe characteristics of popular EOS such as VxWorks, QNX, Window CE, Embedded Linux, Embedded Window XP, and provide the rule for select a operating system that will meet the need of AOS.(2) It selects VxWorks as the RTOS for AOS, according to the demandfor RTOS, give the process of BSP develop for VxWorks. It also provides the way to cut off the VxWorks.(3) AOS require a real time, high performance network protocol, andthis paper give a model of RTNP, which assembles the VIA. It will describe the main components of RTNP, and the transfer models.(4) It implements Internet service for AOS, the multi-tie proxy isused to provide the service.
