Abstract
A method and device for virtual memory support in a computer system using a mapping structure for address translation. Mapping indicators are associated with each process context and each mapping structure entry. When a context is demapped the mapping indicator associated with the context is changed and the mapping indicator in each mapping structure entry is employed to immediately invalidate further memory accesses for that context.
