Research Of RTOS Based On Embedded Linux

Embedded technology has being applied in various industries. As the kernel of its software, the Embedded Operating System is the hotspot of research in information industry. This thesis is based on the study how to rebuild Linux into a high real time operating system.It introduces the research actuality of Embedded technology. On the basis of synthetic comparing manifold Embedded Operating System exiting today, the thesis analyzes excellences and limitations of using Linux constructing Embedded System. Furthermore, It designs Real-time reconstruction project of Linux kernel contraposing these excellences and limitations. It actualizes a Real-time Linux with hard Real-time and condensed kernel. It also advances a improved scheduling arithmetic and improves the Real-time performance based on the study of Linux's scheduling arithmetic.
