arbiter logic

i have done a basic design of ahb master-slave design.
i want to go further in desiging with two masters and four slaves.
what is the arbiter logic should i go for.i mean which arbiter should i choose and how.

You question is not so clear.
As I know, two kinds of arbitrations are popular: round-robin , and fixed priority.
As you said , your system has two masters.
So which master should have higher priority?
Or those masters dont have priority requirement?
Please think further.

usually AHB arbitrator does address decoding and request arbitration, you can refer spec of AMBA 2.0

It might be helpful if you give a little more detail about the system and what you are trying to achieve.

Have you thought about using a multi-layer AHB-lite system? In that case, you have a point-to-point connection between all masters and all slaves and no need for a central arbiter. You have local arbiters at each slave, which are used only when both masters are trying to access the same slave on the same cycle.

Some time ago I wrote an explanation of AHB arbiter operation here:

And a few lines about AHB-lite here:

I think this type of configuration is much more common in ASICs today than the original AMBA conception of a single arbiter for the whole system.
