摘要： The invention provides a system and method of enhancing efficiency in a data processing system having a processor, a memory, and a multitasking operating system for managing the processor and the memory. A normal and an expedited scheduling path are provided for scheduling tasks on the processor. The tasks are each assigned a priority for execution on the processor. A queue is provided for the placement of tasks ready for execution. Upon entry into the ready-to-run queue, the execution priority of the new task is compared to the execution priority of the executing task. Responsive to the new task holding a higher execution priority or to absence of an executing task, the expedited scheduling path is invoked. Otherwise the normal scheduling path is invoked.

摘要： A priority preemptive, time distribution operating system operating in accordance with the method of the present invention provides enhanced efficiency in operation of a data processing system having a central processing unit, a computer memory and an auxiliary memory. The operating system manages the central processing unit, the computer memory and the auxiliary memory where a plurality of processes are presented for execution on the central processing unit by: ordering the processes for execution; allocating a predetermined time slice for execution of a process from the ordering; executing a first current process in the ordering on the central processing unit for the predetermined time slice; responsive to occurrence of a storage access operation during execution of the first current process, allocating a supplemental time slice to the current process for execution; and continuing execution of the current process for the supplemental time slice.

摘要： A method in a computer system for monitoring time intervals during which external interrupts are inhibited within the computer system in a selected program being run on the computer system. The method and apparatus of the present invention includes identifying a first plurality of instructions, capable of blocking external interrupts and identifying a second plurality of instructions, capable of unblocking external interrupts. After identifying these instructions, a unique benign fault is inserted proximate to selected ones of the first plurality of instructions and selected ones of the second plurality of instructions to produce a special version program. The special version program is then run in the computer system. Faults which occur during the running of the special version program and associated external interrupt-blocking times are monitored.

摘要： A system and method for loading a segmented program into a memory for a multitasking data processing system utilizing paged virtual storage for processes is disclosed. A virtual address space having a plurality of pages for the segmented program is established. Segments of the segmented program suitable for packing end to end across page boundaries are identified. A virtual storage object over a contiguous portion of the virtual address space is defined and the segments identified for packing into the virtual storage object are mapped into the contiguous portion. Any segments not suitable for packing across page boundaries start on page boundaries in the virtual address space. Then segments corresponding to selected pages of the virtual address space are demand loaded into frames of the memory in the same manner in which they are addressed into the virtual address space.
