    摘要： The present invention relates to a task scheduling method for a real time operating system (RTOS) mounted to an embedded system, and more particularly, to a task scheduling method which allows a programmer to make a CPU reservation for a task. The task scheduling method for a real time operating system, includes: at a scheduling time point, determining whether or not a highest priority of tasks present in a ready queue is a predetermined value K; if the highest priority is determined to be K, applying a reservation based scheduler to perform a scheduling; and if the highest priority is determined not to be K, applying a priority based scheduler to perform a scheduling; the tasks present in the ready queue, the priority of which is K, contains idle CPU reservation allocation information received as a factor when the tasks the priority of which is K are created.

    摘要： Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.
