11 years agoQsys arbitration works on a per-slave basis. Any master can access any other slave while one slave is already busy.
(4) bridges (masters), each connected to the (4) onchip memories, can simultaneously access all of the onchip memories, so long a no two bridges are accessing the same slave at the same time. If you want to avoid conflict, avoid having your masters access the same memory at the same time (because they will briefly stall, waiting their turn).
