The Porting And Testing Of The Embeded Operating System μCOS

With the rapid development of electronic technologh, Computer technology and Communication technology in Information times and the board application of Internet, and the coming of the post personal computer (PC) times, 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 product to Information product. With the development of the hardware technology and the high demanding of the Information Appliance, Embedded Operating System will be the most favorite thing In this industry. At the same time, in the field ofcomputer science itself, the micromation and specialization is the new direction of the computer world. It also wants the support of Embedded System. So, the research of the critical technique relating to the embedded system is the most important thing.This thesis clearly presents the work of the auther in researching of the embedded operating system:1. Discussing the history, process of the embedded system and the technology level of this period2. Researching the RTOS's construction architecture and details which including resource, Non-Preemptive Kernel, Reentrancy, priority, mutual exclusion, deadlock and so on.3. Doing research in ucos kernel from the memory management, time management, task management, intertask communication, processes, and modules4. Amending part of the cos system kernel, and porting it to the 80x86 processors5. Testing the kernel after porting, and making statistic of the CPU usage rate, present total task number, executing time of each task, and the percent of each task of all task6. Lastly aiming at the work I have done, put forward some task need to be done and describe the potent product in the future.
