class RRArbiter[T <: Data] extends LockingRRArbiter[T]

Hardware module that is used to sequence n producers into 1 consumer. Producers are chosen in round robin order.

Example usage:

val arb = new RRArbiter(2, UInt())
   arb.io.in(0) <> producer0.io.out
   arb.io.in(1) <> producer1.io.out
   consumer.io.in <> arb.io.out
