Abstract

The controller provides storing with equal priority between pairs of resources, by using central processing units which form part of several pairs. The controller has a number of central units, constituting three separate groups. At least three resources are provided to be connected to the individual central processors. First level arbitration units are used to form three double groups, each of which are linked to a respective central processor and a partic. resource pair to select a central pressure in response to a command signal. The arbitration units are connected to one of a pair of resources by pairs of bus lines. Second level arbitration units select one of the central units selected by the first level arbitration units, and function on a rotor basis to allocate access of resource pairs to the requesting central processing unit.
