Design and Implementation of The Priority based Round Robin Scheduling Operating System for Compact Size Embedded System

In this paper, the operating system suing priority based round robin scheduling system is designed and implemented. Using this scheduler, real-time operation is possible because thigh priority task is running first and the other task is running in parallel. Also, inter-task communication, device driver and operating system suitable for using the compact sized embedded system were implemented. Therefore, this operation system provides efficient and rapid implementation for the compact sized embedded system application.
