class Queue[T <: Data] extends Module

A hardware module implementing a Queue

Source
Decoupled.scala
Example: 

  1. val q = Module(new Queue(UInt(), 16))
q.io.enq <> producer.io.out
consumer.io.in <> q.io.deq

Instance Constructors

  1. new Queue(gen: T, entries: Int, pipe: Boolean = false, flow: Boolean = false)(implicit compileOptions: CompileOptions)

    gen

    The type of data to queue

    entries

    The max number of entries in the queue

    pipe

    True if a single entry queue can run at full throughput (like a pipeline). The ready signals are combinationally coupled.

    flow

    True if the inputs can be consumed on the same cycle (the inputs "flow" through the queue immediately). The valid signals are coupled.
