Pipelined crossbar arbitration schemes overcome the time constraints of iterative matching algorithms, allowing support for higher line rates. One such scheme is the fast lowlatency parallel pipelined crossbar arbitration scheme (FLPPR) introduced in [1]. We optimize its performance by applying advanced pre- and post-filter functions. By means of simulation we show that we can simultaneously achieve excellent latency–throughput characteristics under uniform traffic, high maximum throughput under nonuniform traffic, and prevent starvation.
