3.13. Asynchronous AHB-AHB bridge

The asynchronous AHB-AHB bridge, Ahb2AhbAsync32 and Ahb2AhbAsync64, provides a unidirectional link between two AHB domains with asynchronous clocks. Its function is to enable a master to access a slave on another bus, with the transfer initiated from one side only. The asynchronous bridge is not intended for performance applications, because the synchronization logic increases the overhead of a registered bridge design.

The asynchronous AHB-AHB bridge has the following features:
