Hi All,

IF you know can you share these things.....

Which are all the other System on Chip Protocols (like ARM's AMBA, Wishbone, etc... ) using in the industry ?

Which is the Most Commonly used one ?

Which is the best one ?

Which have high speed, bit rate, etc... ?

And Why ?


Thanks in Advance...
 

For this you need to know the difference in different protocols. then you can realize the usage in an SOC.

AMBA AHB:
When you need a single channel for Masters and slaves Communication, then AHB is used.
This bus is shared among all the masters and slaves.
Data rate is low.
Less hardware
Need less power
Bus utilization is more

AMBA AXI:
When you need a multi channel for Masters and slaves Communication, then AHB is used.
Data Rate is high.
more Hardware
more power
Bus utilization is less.

AMBA APB:

APB can't be used as a system bus in an SOC. A bridge is used to connect to AHB subsystem.
Used to connect slow devises.

Go through following link.
Comparing AMBA AHB to AXI Bus using System Modeling
 

Hi Kartheekrs, thank you for your reply.

The thing is that, i know about the AMBA (AXI, AHB and APB) Protocol, but i wants to know which are the other SoC Protocols used for a system design, like Wishbone is an another one.. Like this which are the other protocols that we used...
 

This topic has been discussed before. Please search for it in edaboard. It has all the information you need.

I'm learning bus protocol now. It's useful for me. Thanks all!
