芯粒互联接口中多协议支持技术及标准化研究
Research on multi-protocol support technology and standardization in Chiplet interconnection interface
摘要
Abstract
Chiplet integration has emerged as an effective approach to overcoming the limitations of chip fabrication,memory bandwidth,power consumption,and scalability in the post-Moore era.Estab-lishing standardized Chiplet interconnection interfaces is a prerequisite for heterogeneous Chiplet integra-tion,significantly simplifying Chiplet adaptation,improving the reusability of Chiplets and interconnect interfaces,and accelerating multi-Chiplet SoC design.Since different types of Chiplets adopt varying protocol standards at the protocol layer,Chiplet interconnection interface must support multiple proto-cols.To address this,we propose a multi-protocol support technology based on broad categorization,di-viding protocols into two classes according to their packet characteristics:fixed-pattern protocols and stream-pattern protocols.This technology directly supports protocols conforming to these two catego-ries,while indirectly supporting non-conforming packet types through a"native mode".Additionally,it enables concurrent execution of any two protocols and provides enhanced support for CXL and UCIe.The technology improves indirect protocol support efficiency via micro-packet-level compatibility and achieves complete decoupling between the protocol and adapter layers by delegating link management in-formation embedding in data payloads to the protocol layer.Based on this,we designed a Chiplet inter-connection interface supporting concurrent PCIe and CXL.me protocols and established a simulation ver-ification environment.Experimental results confirm the feasibility and correctness of the proposed tech-nology in multi-protocol support and concurrent protocol execution.关键词
