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.# #
