  • System and method for reducing stack physical memory requirements in a multitasking operating system
    Patent number: 5727178
    Abstract: An operating system component allocates locked stack memory pages to threads on an as needed basis. Each thread has a permanent locked stack. A second locked stack page is mapped to each thread. If a thread is using the assignable locked stack page when the system scheduler switches away from that thread, the assignable stack page becomes owned by that thread. When the system scheduler switches to a thread the assignable stack page mapped to that thread is checked to see if it is owned by another thread. If so, an unowned assignable stack page is mapped to the thread prior to switching to that thread. The size of the pool of locked assignable stack pages is adjusted dynamically. If the number of unowned assignable stack pages exceeds a threshold, locked stack pages are released. If the number of locked assignable stack pages falls below a predetermined number, additional assignable stack pages are allocated.
