• Enables binding of both RAM ports in parallel functions
• User specified strategies to bind ports
• Goal is to reduce contention between parallel hardware accelerators
• Link to presentation

• In config.tcl: add “set_parameter DUAL_PORT_STRATEGY <strategy>
• <strategy> and be “back_and_forth”, “read/write”, or “random”

• Sequentially binds accesses to ports in a round robin fashion
• Seen as the best strategy

• Binds reads (loads) to one port and writes (stores) to the other

• Binds accesses to random port

• User can also specify strategy on a variable by variable basis
• This is done with syntax /*$<strategy>$*/ before a variable name
• For example:
