Master to Master communication in AHB

Kireeti Gudivada

For example, I have an AHB bus with two masters: 1.ARM processor 2. Ethernet MAC , many slaves.

The Ethernet MAC IP should be configured to generate the Ethernet Packets.

Is there any way to use Processor(master)  to configure the Ethernet MAC(master).

    Hi Kireeti, 

    You need to have a AHB Slave bus on the Ethernet MAC IP as well. Most industry IP's by default come with this (AHB Slave is mandatory, AHB Master if it supports features like Internal DMA). The Processor can then access the Register space of the EMAC IP through this AHB Slave controller.
