【Abstract】 In order to meet real time requirement of embedded system, the mechanism of interrupting and task scheduling of Linux is modified in RT Linux, so it can meet demand of high real time system. In this paper the mechanism of interrupting and scheduling in operating system of RT Linux is analyzed .The difference of the mechanism of interrupting and scheduling between RT Linux and standard Linux is shown. The improvement of real time performance of Linux is illustrated更多还原
