Memory array to pio using DMA (Video)

Some DMAs support streaming directly so sometimes you don't even need the FIFO since DMAs have FIFOs inside them. Using SOPC Builder you still need a dummy component in order to get the FIFO/DMA interface up to the top using a conduit. If you used Qsys you could export the ST port of the DMA directly and wire it up to your DAC.
