Research Of RTOS Base On Linux2.6 Interrupt System And Scheduling Algorithm

Linux as one of mainly opening source software, which make it obtained the low price and powerful function. The Core modular design and the Core Highly reductive make it got more attention in embedded operating systems. But Linux originally is designed as a common and time-sharing operating system, which limited its real-time. So Linux must be effective real-time extension in practice to fit the demand of embedded system's real-time function.In this paper, the real-time operating system's basic theory was introduced to provide the theoretical basis for follow-up discussions and tasks demand, then analysis the Linux operating system architecture and the task response time, explained the reasons of inferior for the Linux real-time system. Then provide various solutions, finally realized the test and the corresponding evaluation.
