One memory loads and#    reorders data, while the other memory dumps the data to the output.#    Once loading and dumping of data are complete, the memories reverse roles.#    The dumping memory continuously cycles though the entire memory starting at address 0.#  #  Interface:#  #    Synchronization:#      clock_c  : Clock input.#  #    Inputs:#      swap_i   : Swap signal to interleave memories.  Pulse occurs one frame before the switch#                 and may coincide with the last input data.#      write_i  : Write enable for input data.#      addr_i   : Address for input data.#      data_i   : Input data.#  #    Outputs:#      sync_primary_o    : Output sync plus occurs one frame before data new dump.#      sync_secondary_o  : Secondary sync plus occurs one frame before data at address 0 is dumped.#      data_o            : Output data.#  #  Built In Parameters:#  #    Address Width  = 9#    Data Width     = 64#  #  #  #  #  Generated by Confluence 0.6.3  --  Launchbird Design
