Compute Express Link: The Breakthrough CPU-to-Device Interconnect


Upcoming Webinar

Introducing the Compute Express Link™ 2.0 Specification

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.

Presenters: Debendra Das Sharma (Intel) and Ahmad Danesh (Microchip)
Date: December 10 at 9 AM PT

Memory Challenges and CXL Solutions

Airing Date: August 6, 2020

Compute Express Link™ (CXL™) is an industry supported cache-coherent interconnect for processors, memory expansion and accelerators. CXL supports dynamic multiplexing between a rich set of protocols that includes I/O (, based on PCIe®), caching (CXL.cache) and memory (CXL.memory) semantics. CXL.mem allows a host processor to access memory attached to a CXL device. CXL.mem transactions are simple memory load and store transactions that run downstream from the host processor which takes care of all the associated coherency flows.

This webinar will explore how the CXL.mem protocol can deliver power-efficient performance with emerging applications such as AI, HPC, DL and comms with a coherent interface and low latency. This webinar will also explore type-3 devices and use cases for memory bandwidth expansion, memory capacity expansion and storage class memory.

Exploring Coherent Memory and Innovative Use Cases

Airing Date: March 12, 2020

Siamak Tavallaei, CXL Consortium Technical Task Force Co-Chair and Principal Architect, Microsoft Azure, Rob Blankenship, Processor Architect and Principal Engineer, Intel, and Kurt Lender, CXL Consortium Marketing Working Group Co-Chair and Senior Ecosystem Enabling Manager, Data Center Group, Intel, take listeners into a deep dive about CXL technology maintains memory coherency between the CPU memory space and memory on attached devices.


The webinar also details several representative CXL use cases – Caching Devices/Accelerators, Accelerators with Memory, and Memory Buffers.
