4.4.2. Optional TREADY Signal: Receiver Interface

The Intel FPGA streaming full-raster video protocol follows the AMBA AXI4-S protocol recommendation.

It states that TREADY is an optional signal that you can omit in certain circumstances if the receiver interface can always accept a transfer. However, if TREADY is not supported as part of the full-raster interface, but the actual signal cannot be removed from the receiver interface, drive TREADY high all the time.
