Simple arbiter which grants access to the highest-priority requester that is active.
Source file: Fixed Priority Arbiter
Arbiter which grants access to a requester only in fixed, pre-defined time slots regardless of request activity.
Source file: Time Division Multiplexed (TDM) Arbiter
Arbiters grants active requesters in circular queue order, to provide basic fairness to every requester.
Source file: Round Robin Arbiter
Similar to RR Arbiter, but extends the round robin scehduling by assigning pre-defined weights per-requester, allowing some to receive multiple consecutive grants.
Source file: Weighted Round Robin Arbiter
Similar to WRR Arbiter, but interleaves the grants across requesters according to their weights, reducing latency and avoiding long service bursts for any single requester.
Source file: Interleaved Weighted Round Robin Arbiter
Arbiter which uses per-requester deficit counters to fairly schedule variable-sized packets while maintaining proportional bandwidth.
