Ann2 n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input.
It picks the first 1 and outputs i ndex in one-hot encoding. RRA aims to be fair to its inputs and
maintains fairness by simply rotating the input priorities, i.e., the last arbitrated input becomes the
lowest-priority input. Arbiters are used to multiplex the usage of shared resources among requestors as
well as in dispatch logic where the purpose is load balancing among multiple resources.
