19.3.3.1 Arbitration Rules

Each arbiter has the ability to arbitrate between requests from two or more Hosts. To avoid burst breaking and to provide maximum throughput for Client interfaces, arbitration should take place during the following cycles:

• Idle cycles: When a Client is not connected to any Host or is connected to a Host which is not currently accessing it
• Single cycles: When a Client is performing a single access
• End of Burst cycles: When the current cycle is the last cycle of a burst transfer. For a defined length burst, predicted end of burst matches the size of the transfer but is managed differently for undefined length burst. Refer to the "Undefined Length Burst Arbitration" section.
• Slot cycle limit: When the slot cycle counter has reached the limit value indicating that the current Host access is too long and must be broken. Refer to the "Slot Cycle Limit Arbitration" section.
