CRC Interface
This Figure illustrates checking CRC at the core level. The figure shows 6 n bytes of received data of a frame. At the end of the frame, the core asserts m_axi_rx_tlast and crc_valid . In the same clock cycle the transmitted and computed CRCs are compared. If the values match, the crc_pass_fail_ n signal is asserted.
