The Research & Development Of Embedded OS Based On PSOS Kernel

With the development of Computer technology and Communication technology in Information times and the broad application of Internet, it is clear that 3C (Computer, Communication and Consumer) will converge in the near future which will lead the focus of Computer Industry from the Compute products to embedded products. In the application and development field of Information Appliance & communication Embedded Operating System will be the most favorite thing in Software Development field. At the same time, in the field of computer science itself, the micromation and specialization is the new direction of the computer world. It also wants the supportof Embedded System. So, the research of the key technique of embedded system----Embedded Operating System is the most important thing.This thesis presents the author' s work in research & practice of the pSOS-based Embedded Operating System for his master degree. Most of the thesis focuses on the discussion of the design & implementation on developing the imitation system and simulating the function of pSOS' kernel. Firstly, it describes the history, current and concepts of embedded system, and researches the Embedded OS' structure & running theory & the integration environment detailedly. Then the paper describes particularly three aspects of the imitation system in the management of tasks and the schedule of tasks and synchronization & communication. I have also involved the argumentation of inosculating application and realizing project and programming method. In the last part of this thesis, according to the progress of embedded system,I put forward that the present work will be perfected farther in order to make the imitation system have powerful market in the developing field of Embedded application.
