A method and apparatus for reducing arbitration latency. A fast mode is defined to allow simultaneous request and access to a shared resource. A slow mode is defined to require a request, followed by arbitration, followed by access to the resource. By dynamically switching between fast and slow modes responsive to the volume of requests received, arbitration latency is reduced.
