Choosing Between CCIX and CXL

May 19th, 2020 - By Ed Sperling

Experts at the Table, Part 2: What's right for one design may not be right for the next. Here's why.
 
Kurt Shuler, vice president of marketing at Arteris IP said, "When CCIX first came out, there was a lot of discussion about doing larger-scale, symmetric cache-coherent systems. But as you add in die or separate chips, and you have to increase memories and caches — and data for what’s going on in the different die, and locally storing that — there’s an architectural line where it doesn’t make much sense anymore. Are you actually losing more than you’re gaining? It’s really, really hard for architects to figure out where that hump is. Even if you have 20 years of experience as a cache-coherent architect, you can’t figure this out anymore in your head or by using Excel. That doesn’t work with CCIX and CXL".

Semiconductor Engineering: Which Chip Interconnect Protocol is Better?

Which Chip Interconnect Protocol is Better?

Experts at the Table: CXL and CCIX are different but it's not always clear which is the best choice.
 
"Everybody is circling around and trying to figure out what everybody else is doing, said Kurt Shuler, vice president of marketing at Arteris IP. CCIX is a little different. The idea there was that you would have one or more chips and they would all be one cache coherent system. So in the case of CXL, the coherency is all managed on the Xeon side, and that companion chip is always a slave. It’s different with CCIX. So if you do the bi-directional coherency, which is what people are interested in, it’s one big cache-coherent system".
