Data input memory bank swap
Figure 5 : Memory bank swap
When the core requires a new pass to be computed, it needs to get the results data from
the previous pass as input data. A pass transition is indicated by an inversion of the
din_bank signal. This signal can be used to multiplex the memory banks connected to the
core during processing.
