An apparatus and method for fairly arbitrating between clients with varying workloads. The clients are configured in a pipeline for processing graphics data. An arbitration unit selects requests from each of the clients to access a shared resource. Each client provides a signal to the arbitration unit for each clock cycle. The signal indicates whether the client is waiting for a response from the arbitration unit and whether the client is not blocked from outputting processed data to a downstream client. The signals from each client are integrated over several clock cycles to determine a servicing priority for each client. Arbitrating based on the servicing priorities improves performance of the pipeline by ensuring that each client is allocated access to the shared resource based on the aggregate processing load distribution.
