RRArbiter

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.

Source
ChiselUtil.scala
Example: 

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