 .. [#] ``ReadQueue`` and ``WriteQueue`` are good illustrations of how to write a ``DspBlock`` and how they can be integrated into rocket, but in a real design a DMA engine would be preferred. ``ReadQueue`` will stall the processor if you try to read an empty queue, and ``WriteQueue`` will stall if you try to write to a full queue, which a DMA engine can more elegantly avoid. Furthermore, a DMA engine can do the work of moving data, freeing the processor to do other useful work (or sleep).
