Chiplet interoperability and breakthroughs in AI

By Francisco Soca, Arm and Jonathon Evans, Nvidia

Chiplets offer greater system composability and performance scaling- making them attractive for AI and accelerated computing. To be adopted at scale- chiplets need to be interoperable. Interoperability is achieved through the standardization of chiplet interfaces and protocols.

AMBA CHI C2C is an extension to the widely adopted on-chip CHI protocol for connecting chip(let)-to-chip(let). This presentation shows how AMBA CHI C2C can be used to coherently and securely connect Arm-based systems-on-chip to accelerators over C2C to enable breakthroughs in AI and accelerated computing.Arm and NVIDIA have been collaborating to lay the foundations of this extension. As part of this presentation- NVIDIA will discuss the value of a native AMBA CHI interface as a chiplet interface for accelerator attach.
