Native Interface Handshaking

The i_we, i_re, o_wr_ack and o_rd_ack ports provide the handshaking mechanism.

  • The SDRAM controller keeps outputting data with o_valid asserted without any triggers.
  • It is assumed that the master module always has buffers for handling both read and write handshaking.
