ANORDNING FOR RESURSSELEKTERING, SERSKILT BUSSELEKTERING I EN MULTIPROCESSOR

摘要

The selector arrangement is for units requiring resources with several common resources whose number is less than that of the units. An input for each resource-requiring unit receives a signal concerning the requirement of a resource, and an address output is provided to each resource-requiring unit which furnishes addresses (BA) for the resources allocated to the units. Between the inputs and outputs is connected a combination network which produces the address to a resource as a mathematically calculated sum for allocation to the resource-requiring unit if the latter has given a requirement signal, and if the sum is less than or equal to the resource number. The resource-requiring units are the process stages of a multi-processor, and the resources are buses with connection of the process units with parts other than their own memory connection.
