Re: [interconnects-wg] Advanced Interface Bus repository is live

Hi G S,


I intend to continue CHIPS Alliance and Intel in alignment in general.  Importantly, Intel is committed to compatibility with chiplets made to the current spec, much like PCIe Gen1/2/3/4/5 supports earlier versions.  This makes sense for all of us given the very substantial investment in the portfolio of chiplets from multiple companies.


Check out page 13 of this presentation:

It describes the technology drivers for the future of AIB.  I plan to elaborate on these soon to gain feedback from the CHIPS Alliance members towards a 2.0 specification.  To your point about spending effort on AIB enhancements, yes for a 2.0 that is likely faster, lower voltage and more dense you will likely see benefits in using it.


I’m happy to have discussion about this with you, just let me know.

I had asked this question earlier when AIB was Intel internal . I know Intel has a roadmap for AIB variants internally. Will Chips Alliance have its own roadmap or will we be tracking Intel's roadmap. We plan to use AIB extensively for hpc designs , so would be useful to know if we need to spend efforts on AIB enhancements.

The AIB spec in the docs directory now wears a CHIPS Alliance logo as well. The old site now has this readme:
