摘要： A system and method for arbitrating for access to a resource group between agents according to a respective programmable weight for each agent. For each agent, a programmable mapping module selectively couples a respective arbitration handshake signal of the agent to one or more arbitration ports, and the number of the coupled arbitration ports for the agent is the respective programmable weight. A selection module selects one of the arbitration ports in response to a priority ranking of the arbitration ports, and access to the resource group is granted to the agent that has the respective arbitration handshake signal that is selectively coupled by the programmable mapping module to the selected arbitration port. A ranking module provides the priority ranking of the arbitration ports and updates the priority ranking in response to the selection module selecting the selected arbitration port.
