ABSTRACT:
A task status word (TSW) is created for each task indicating, the instant location of the task, its priority and a record of synchronizing signals. Task status words are accessible from an addressable memory section for delivery to a TSW register. From the TSW register, a selected TSW effects control functions to synchronize tasks in different processors or computational units as well as input-output processors. A physical memory manager locates TSWs in response to signals, then checks the location of the task and the nature of the signal to determine signal routing to a processor. If a task is not in a processor, an interrupt manager resolves priority and signal significance indicated by the TSW to determine an interrupt.
