Analysis Of The T-engine Embedded Platform And Applied Research

With the rapid development of digital technology based on computer and software, the embedded system become a hot research point. In the area of manufacture industry, process control,martial equipment,aeronautics and astronautics,embedded real-time operation systems become more and more important. The theories and technical problems related with Embedded Operating System have also become hot spot of research and development. Especially, to ensure real-time characteristics as well as resources effective management in Embedded Operation System .TRON is an open real-time OS specification which was started by Sakamura of Japan. The OS nucleus according to TRON has been widely applied in the area of consumer equipment, industrial control, mobile equipment, and etc, making it one of the most-used OS.T-Engine is the open standard platform for embedded systems which is developed by TRON for standardize. It is constituting with standard hardware(T-Engine) and standard real-time OS kernel(T-Kernel).With the support of embedded innovation laboratory of NWPU and with the background of the work in international cooperation project "the research of embedded real-time OS TRON" which belong to embedded key laboratory of shan'xi province and TOPPERS Association in Japan, this paper analyses and researches applications on the embedded real-time operation system platform based on TRON specification.The main work is done as follow:1. The T-Engine development platform and its hardware and software structure specification are researched.2. Based on the analysis of the kernel source code of the OS T-Kernel on the base of TRON specification, the scheduling tasks is researched more deeper. The advantage and disadvantage of scheduling tasks adopted by the system are analysed.The priority inheritance protocol solution is proposed in view of the emergence of the priority inversion problem. Then the priority inheritance protocol is integrated into the system.Finally, the correctness of the algorithm is verificated by experiment.
