    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： Provided is a method of managing memory in a multiprocessor system on chip (MPSoC). According to an aspect of the present invention, locality of memory can be reflected and restricted memory resources can be efficiently used by determining a storage location of a variable or a function which corresponds to a symbol with reference to a symbol table based on memory access frequency of the variable or the function, comparing the determined storage location and a previous storage location, and copying the variable or the function stored in the previous storage location to the determined storage location if the determined storage location is different from the previous storage location.

    摘要： A method and apparatus for detecting errors in an application software of an embedded system are provided. The method of detecting errors in an application software includes determining a development language of the application software and an operating system on which the application software is executed; replacing an error detection syntax inserted in order to examine an error in a predetermined function of the application software, with an error detection syntax according to the result of the determination; and performing exception handling for an error occurring in the function according to the result of the replacement, and logging error information according to the exception handling. According to the method and apparatus, an error can be automatically detected and logged irrespective of a development language and an operating system.
