Introducing the Compute Express Link™ 2.0 Specification

Presented by

Debendra Das Sharma (Intel) and Ahmad Danesh (Microchip)

About this talk

The CXL Consortium is proud to announce the second-generation Compute Express Link™ (CXL™). CXL is an open industry-standard interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between host processor and devices such as accelerators, memory buffers, and smart I/O devices. This webinar will explore the new features in the CXL 2.0 specification including support for switching for fan-out to connect to more devices; memory pooling for increased memory utilization efficiency and providing memory capacity on demand; and support for persistent memory – all while preserving industry investments by supporting full backward compatibility with CXL 1.1 and 1.0.
