      AxiFifoAdapter: improve performance · fe9d7b90
      Jens Korinth authored
      * now stays in fetch mode and just flips buffers, if current FIFO
        is empty
      * empty checks more aggressive: now checks if FIFO will be empty
        in the next cycle to mask the state transition

      AxiFifoAdapter: implement AXI mem to FIFO adapter · 9684a9c2
      Jens Korinth authored
      * tick-tock buffer approach: one buffer is filled via AXI4 read
        bursts, the other is made available for dequeuing
      * can provide continuous data at full speed, given that the bursts
        finish fast enough
      * also added some unit tests for fixed blocks of memory
      * missing: support for wrap-around (currently via reset)

      First draft of FifoAxiAdapter · 4443aa0c
      Jens Korinth authored
      * adapter to write data from Decoupled-Fifo as AXI4 master
      * base address supplied as input
      * all widths configurable
      * FifoAxiAdapterTest1 uses DecoupledDataSource to test with
        constant data set
      * can also be used to verify against AXI BFMs
