Abstract


According to the trends of the day-to-day work of the functional requirements of the embedded operating system , as well as the current x86CPU proposed R \u0026 D based on the 32 x86CPU embedded operating system . This article by the embedded operating system applications and the development of research and analysis of the operating system principles to determine the frame structure of the system developed in this study . Analysis and the CPU to switch from 16-bit real mode to 32-bit protected mode , based on round-robin preemptive kernel , the introduction of the priority tasks of the same priority number concept , to achieve the same priority tasks allocation and the first to adapt the method of memory allocation algorithm . The system debugging environment , design and test solutions for task management module , memory management module in the system , and successfully passed the test . For the convenience of system debugging , loading the kernel and basic console driver under DOS system . The last independently developed a 32-bit - based embedded operating system in x86CPU .
