5.10.9.1. Transaction Cannot Cross 4KB Boundaries

When an Avalon® host issues a transaction to an AXI subordinate, the transaction cannot cross 4KB boundaries. Non-bursting Avalon® hosts already follow this boundary restriction.

When connecting an Avalon® memory-mapped interface FPGA host to an AXI subordinate in Platform Designer, you must ensure that the bursts do not exceed the AXI3 or AXI4 4KB boundary restriction for burst transactions.
