Abstract
In this study, we have proposed the random function arbitration method using a random function manager in other to use the merits and overcome the demerits of fixed priority and round-robin, Starvation phenomenon can be generated from the master having low priority in fixed priority method. Also, round-robin method can't give a priority to important master, however, as the proposed random function arbitration method can be random set the rate of fixed priority and round-robin, we can solve the problems of conventional arbitration methods. From TLM simulation, we confirmed that the bus utilization of master could be controled from 32% to 16% and the starvation phenomenon of master could be prevented.
