Abstract
A system page is implemented to provide direct access to operating system data structures by user tasks. Frequently accessed data structures are located in the system page, and may be linked against during linking. The system page memory locations are mapped into user tasks as read-only memory locations, allowing read-only memory accesses during run-time. The system page reduces execution overhead without sacrificing system security.
