    摘要: Provided is a method and apparatus for preventing a stack overflow in an embedded system. The method of preventing a stack overflow includes: reading a maximum stack usage of at least one function for executing a requested operation from maximum stack usages of functions provided from a kernel, which are stored in advance; and processing the requested operation on the basis of the read maximum stack usage of the at least one function and a size of a usable region in a stack for the requested operation. Accordingly, the stack overflow can be prevented without generating a run-time overhead.

    摘要: A scheduling method, medium and apparatus are provided. In the scheduling method, medium and apparatus, it is possible to prevent the possibility that the order between the priorities of the tasks represented by the expired timers and the tasks requested by the interrupt is reversed while also not deteriorating the performance of a real time operating system (RTOS), even though the number of timers expired when the interrupt occurs or that are already expired before the interrupt occurs is large, by selecting a timer for representing a point of time corresponding to a point of time when an interrupt occurs from among one or more timers each of which representing a task, a point of time assigned to the tasks, and a priority assigned to the task and executing a task represented by the selected timer and one or more tasks requested by the interrupt in order of priority.
