Data Interleaving: In a multi master interconnect, lets consider master A initiated the transfer with a burst of 4 and master B with a burst of 2 then it follows as A1 B1 A2 B2 A3 A4 it means A started the transaction, then went to B because of idle cycle by A and again A likewise. There are many uses for interleaving at the system level, including: Storage: As hard disks and other storage devices are used to store user and system data, there is always a need to arrange the stored data. But it's not the only possible source of interleaved write data. The controller implements a table shared across all masters, which can store up to 16 pending writes. Interleaving is more effective than 'blocking' as it allows you to link ideas together and relate concepts to one another to understand the bigger picture. The base addresses for slaves in the interconnect are also hence assigned in multiples of 4K. Axi handshake.
