The arbitration type is round-robin arbitration. This algorithm dispatches the requests from differ-
ent masters to the SDRAM device in a round-robin manner. If two or more master requests arise
at the same time, the master with the lowest number is serviced first, then the others are ser-
viced in a round-robin manner. To avoid burst breaking and to provide the maximum throughput
for the SDRAM device, arbitration may only take place during the following cycles:
1. Idle cycles: When no master is connected to the SDRAM device.
2. Single cycles: When a slave is currently doing a single access.
3. End of Burst cycles: When the current cycle is the last cycle of a burst transfer. For
4. Anticipated Access: When an anticipate read access is done while current access is

bursts of defined length, predicted end of burst matches the size of the transfer. For
bursts of undefined length, predicted end of burst is generated at the end of each four
beat boundary inside the INCR transfer.
not complete, the arbitration scheme can be changed if the anticipated access is not
the next access serviced by the arbitration scheme.
