6.12.1. Burst Support

Platform Designer supports INCR bursts up to 256 beats. Platform Designer converts long bursts to multiple bursts in a packet with each burst having a length less than or equal to MAX_BURST when going to AMBA* 3 AXI or Avalon® agents.

For narrow-sized transfers, bursts with Avalon® agents as destinations are shortened to multiple non-bursting transactions in order to transmit the correct address to the agents, since Avalon® agents always perform full-sized datawidth transactions.

Bursts with AMBA* 3 AXI subordinates as destinations are shortened to multiple bursts, with each burst length less than or equal to 16. Bursts with AMBA* 4 AXI subordinates as destinations are not shortened.
