Abstract
With microprocessor development, a wide range of low price, compact structure of the CPU and peripherals and provide a stable, reliable hardware architecture. Embedded system development is now the bottleneck in the software, especially operating systems, "embedded" change. Due to the open-source Linux, concise, multi-task, multi-task and easy to transplant, and low cost characteristics, as many research and application of choice target. With release 2.6 of the kernel, Linux to the mainstream of the existing real-time operating system providers, the greater the challenge, is bound to become more outstanding Embedded operating system.
I got interest with Linux operating system several years ago. Combination my specialty, Then I did some research for real-time Linux. Based on these facts, this thesis demonstrates architecture and internals of Linux system used on embedded systems. The paper outlined the systems and embedded real-time system development, Then real-time Linux in the field of research, followed by about embedded Linux system in the structure, Description of the final system testing strategies, and on the next steps to continue the work forward.
Key words： Real Time System, Embedded System, process, Linux
