Abstract


Show good prospects for the embedded real-time control of the product , not only for the embedded market , as well as embedded systems technology , especially of embedded real-time operating system a new challenge . Embedded real-time operating system is a development platform for embedded applications , it is designed for a variety of underlying hardware , and provides a unified programming interface for application software developers , embedded real-time operating system must have a very good real-time performance to meet its real-time response to external events . The Linux operating system because of its open source , the height of the kernel can be cut to make it in the field of embedded real-time concern . But Linux is a general-purpose time-sharing system , which limits its application in embedded real-time systems , improved real-time , in order to meet the requirements of real-time performance . This paper introduces the basic concepts of real-time embedded operating system , and Linux operating systems analysis and design , so that it can meet the requirements of real-time systems and embedded systems . The paper focuses on two aspects of the real-time operating system and embedded operating systems design and implementation. In a real-time operating system , Linux for real-time tasks with certain considerations , but falls far short of hard real-time requirements , through analysis of scheduling the timing and scheduling policy pointed out that the key factor in the impact of real-time performance . There are many Linux real-time performance improvement program , through a comprehensive analysis and comparison , selected RT-Linux research and applications . The final design and cut out a CNC system can be used for real - time embedded linux u disk system .
