Multi-phase subroutine control circuitry |
摘要 |
Multi-phase subroutine control apparatus for use in a data processing system which provides for the concurrent execution of a plurality of tasks in a multiprogramming and multiprocessing environment. Subrouting control operations are staged so as to share common hardware in a manner which in effect provides a plurality of phased concurrently operating subroutine control circuits wherein each circuit provides control for a different one of a plurality of concurrently executing tasks. The common subroutine hardware includes a multi-level stack for each task and a fast access return address register which permits a return address to be rapidly made available when required during execution of a task.
