Abstract
A method, system and circuit for performing a round robin arbitration, which includes an input operable to receive a plurality of requests, a conditional request masking logic to selectively send the plurality of requests to a priority encoder, a priority encoder to output a request from the selected plurality of requests from the conditional request masking logic for servicing, and a storage clement to store the most recently serviced request. Wherein the conditional request masking logic sends any request from the plurality of requests that has a lower priority according to said priority encoder than the most recently serviced request if such a request exists, otherwise all requests are sent to the priority encoder.
