An arbitration parking apparatus and method for a split transaction bus is provided. Processor agent(s) and memory agent(s) are connected by a split transaction bus which includes an arbiter to control access to the split transaction bus. The arbitration parking scheme includes parking a memory agent if there is an outstanding request. If there is no outstanding request and neither a processor nor memory agent request, then the arbiter parks either a memory agent or a processor agent depending on system characteristics. By parking the agent to request access to the split transaction bus next, arbitration overhead is reduced.
