This module accepts an AxisDataStreamType AXI4 type data stream with 256 bit width data. It performs a Fifo function outputing the data on a 128 bit wide AxisStreamType AXI4 type stream. The last signal is passed through the Fifo. The FIFO depth is configurable with the FifoSizeBytes parameter which is in Bytes. For the NvmeStorage system this is normally set to the block size of 4096 Bytes. The modules uses block RAM to store the data.
