Achieving the potential of chiplets requires standardization. Well-defined chiplet types and a layered approach to standardization are prerequisites to a vibrant chiplet marketplace. A new family of standards will help designers build reusable chipsets that they can integrate into multiple systems. It will extend the Advanced Microcontroller Bus Architecture (AMBA)’s on-chip Coherent Bus Interface (CHI) to a chip-to-chip (C2C) version suitable for connecting chip(let)-to-chip(let). These initiatives will complement other chiplet standardization work such as UCIe to drive further alignment and collaboration.
