Design And Implementation For Airborne High-reliability Real-time Operating System

At the early age of embedded system history, many real-time operating system use multi-task sharing single address space mode, which means kernel and application run in the same priviledge and application can access the whose address space with full pomission, for the limited performance and hardware resource. But in the reality, kernel will occur fault even crash by the user's malicious operation.On the another hand, along with the development of microprocessor and embedded application, there are many kind of high performance embedded processor supporting the MMU and high level protection mode. This is the base to to build an isolated and protected operating system, which can guarteen the destroy and impact between applications.The above two points promote the emergnation of embedded real-time operating system. At the same time, this kind high reliable and fully protected embedded real-time system become widely application in many safety-critial area.Through the detailed analysis of safety-crital system software speciation ARINC653 and several main stream commercial real-time operating system kernel, We designed and implemented a high available and reliable real-time operating system ARTOS, which is as well as the same catagerous system on functionality and performance, based on our technology.
