CXL Consortium

Compute Express Link™ (CXL™) is an industry-supported Cache-Coherent Interconnect for Processors, Memory Expansion and Accelerators. CXL technology maintains memory coherency between the CPU memory space and memory on attached devices, which allows resource sharing for higher performance, reduced software stack complexity, and lower overall system cost. This permits users to simply focus on target workloads as opposed to the redundant memory management hardware in their accelerators. 

​CXL is designed to be an industry open standard interface for high-speed communications, as accelerators are increasingly used to complement CPUs in support of emerging applications such as artificial intelligence and machine learning.

The CXL Consortium is an open industry standard group formed to develop technical specifications that facilitate breakthrough performance for emerging usage models while supporting an open ecosystem for data-center accelerators and other high-speed enhancements.
