ABSTRACT:
A method and apparatus for arbitrating among a plurality of processors for access to a common system bus in a multi-processing system are provided. The bus arbitrating method includes the steps of detecting a request signal from a processor requesting access to the system bus, checking the number of other processors in the system requesting access to the system bus, providing access to the system bus by considering a priority factor among competing processors when the number of processors requesting access to the system bus is below a predetermined number, and providing access to the system bus by considering only a fairness factor when the number of processors requesting access to the system bus is not below the predetermined number. Accordingly, bus access speed can be improved by considering principles of both fairness and priority.
