Abstract
An apparatus and method for allocating virtual memory upon demand to reduce the amount of virtual memory allocated. Privilege level transitions requested by a program of instructions invoke a fault handler routine which allocates memory for implementing the transition. Allocation of memory is thus delayed until such request for privilege level transition occurs.
