ABSTRACT:
A central arbiter uses priority generators to determine which resource on a shared bus has priority in accessing the bus. Each resource has a corresponding priority generator. Each priority generator has a counter having inputs and outputs. A starting value is provided at the inputs and the priority value is obtained from the outputs. Each priority generator has a comparator that compares the outputs of a counter with a modulo number of the counters, N. The priority generators provide a combination of fixed priority and round robin arbitration schemes. By selecting the value of N relative to the number of resources, the rate of round robin access relative to fixed priority access can be set.
