How do you connect an AHB-lite Master to a full AHB system?

Applies to: AHB


You will need logic to add the HBUSREQ and HGRANT signals, to advance the timing of the HLOCK output to be ahead of the LOCKed transfer address phase, and to support SPLIT or RETRY responses on HRESP.

None of this logic is trivial, so you would need an AHB-lite master wrapper, such as the Lite2Ahb component found in ARM's AMBA Design Kit (ADK).
