Abstract
A decentralized arbitrator includes an individual elementary arbitrator and a level elementary arbitrator for each arbitration unit. Determination of the priority due to one unit, when no other unit claims priority, is accelerated by directing the request states of all units on the same level and on all other levels to the input of an AND gate, the output of which is connected to the bus-utilization enablement input of the relevant unit, through an OR gate and a D flip-flop.
