Research On Embedded Linux Rtos And It's Scheduling Policy

With the rapid development of computer technology and consumer electronic technology, embedded industries has risen rapidly in recent years and it has become the fastest-growing, and most concerned industry. While embedded systems have been more and more used , a vast opportunity of market is embedded . Embedded system usually work in the hard real-time environment,so it is often real-time system. The research of Real Time Operation System(RTOS) is an important area of embedded system research. Linux is sparkle for its open source, low cost and powerful function in the area of embedded system. RTOS based on Linux has become a hot field of research and development recent years.In real-time system, task scheduling policy is the key part of kernel design. How to design task scheduling to ensure all the tasks complete before its deadline is an important problem of real-time operating systems research. There are quite a lot of researchs focused on the aspect of theoretical research currently, but the adoption of algorithms in real system is merely achieved.After introducing embedded real-time operating system, this article makes an comparison of the improvement schemes to Linux real-time...
