Abstract:
A data processing system including a processing unit for program execution and data processing, an operating system program for controlling the operation of said data processing system, and a service call logical processor, said data processing system comprising in combination:a pool of increments of physical memory from which pool of increments of main memory address locations and increments extended memory address locations are assigned;a configuration table including flags indicating the assigned status of an increment in said pool of increments of physical memory as an increment of main memory address locations, as an increment of unassigned main memory address locations, as an increment of extended memory address locations, or as an increment of unassigned extended memory address locations;said service call logical processor dynamically changing an increment status in said pool of increments of physical memory by means of a service call instruction which changes a flag associated with the increment to be changed without disruption of the operating system program or any application program.
