which bus architecture for my SoC design?

[Laplace]

Is there any one who would like share his/her ideas on *optimal choice of SoC bus architecture?

Thanks..

You could evaluate AMBA (Advanced Microprocessor Bus Architecture)
proposed from ARM for SoC design. Looks well documented and has been used for ARM710 etc.

Also at xxx.opencores.org look for the Wishbone specifications. Many of open source designs there use Wishbone.

I think that AMBA is a good choice, becouse it has well-document and many IPs fellow AMBA specification. Most importance is that AMBA is open.

I would like to design with AMBA.
For high bandwidth, it provides the AHB/ASB with pipeline feature.
For low speed periperal, it defines the APB.

WISHBONE is also good, it is easy and left TAG for user-defined using.
But there it is not suitable for pipeline operation.

Has anyone used I/B/M's Core/Connect before?

it depends on what speed of your system and what speed of the interfaced system.

Yo to AMBA

I agree with EDAguy, but if you are looking at ease of imp at a decent performance AMBA would be the choice.

i need a simple but fast responsive bus architecture.. what about Wishbone?
