Abstract
An apparatus and method for managing stacks for efficient memory usage. The apparatus includes a fault cause analysis unit to recognize a page fault caused by a marking page; a control unit to set the marking page, to request compression of a first stack page depending on whether a page fault occurs, to release a mapping of a second stack page that becomes empty due to the compression, and to return the second stack page; a memory allocation unit to receive the second stack page and to allocate a new stack page to the control unit upon completion of the compression; and a compression unit to compresses the first stack page at the request of the control unit.
