interfacing a WishBone IP core to a CoreConnect bus

Dec 18, 2003 3 Replies

Is there anybody who has experience at interfacing a WishBone IP core to a CoreConnect bus. Specifically the design of a bridge ?



regards,

No, but I would be very interested in such a thing! Opening up the whole opencores library to use with microblaze would be a great boost for both.

An interesting aside for those using Altera products: The Avalon bus interface and Wishbone are close enough to each other to make this very simple.

A while ago I studied the feasibility of this using Avalon and the Ethernet MAC core on opencores.org. You can wire up a Wishbone slave to Avalon in the SOPC Builder tools with a few mouse clicks. No bus bridge required. Wishbone masters require a bit of RTL to implement their "acknowledge" signal but other than that everything falls together automatically.

Ok thanks for your reply but we are using a virtex pro with powerpc or microblaze. Trouble is as John said, we cannot use the free cores. So it would be nice to have a bridge.

Tom
