摘要

An arbitrating apparatus, having a filtering circuit operatively coupled with a bus grant circuit, is provided. In one example of operation, a plurality of bus request signals are transmitted simultaneously to the filtering circuit. The filtering circuit permits one of the bus request signals to pass to the bus grant circuit where the passed bus request signal is matched with a bus grant signal, which bus grant signal is used to obtain access to a video bus for one of a plurality of bus masters.
