Compute Express Link™: The Breakthrough CPU-to-Device Interconnect
Date: October 6, 2022
Time: 9 am PT
In August 2022, CXL Consortium released the CXL 3.0 specification. CXL 3.0 expands on previous technology generations to increase scalability and optimize system level flows with advanced switching and fabric capabilities, efficient peer-to-peer communications, and fine-grained resource sharing across multiple compute domains. It also doubles the data rate to 64 GT/s with no added latency over CXL 2.0, while maintaining backward compatibility with previous specifications.
This webinar will introduce the CXL 3.0 specification and explore the new features including:
• Fabric capabilities and management
• Dynamically composable systems
• Improved memory sharing and pooling
• Enhanced coherency
• Peer-to-peer communication
• Doubled data rate with no added latency

In November 2020, the CXL Consortium released the CXL 2.0 specification which introduces support for switching, memory pooling, and support for persistent memory – all while preserving industry investments by supporting full backward compatibility. Based on member feedback, CXL 2.0 ECNs made significant improvements to the specifications in the areas of device management, RAS, Security, memory interleaving and others.
This webinar will review the key CXL 2.0 specification ECNs and the new usages they enable.

Compute Express Link™ (CXL™) is an open industry-standard interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between the host processor and devices such as accelerators, memory buffers, and smart I/O devices. The CXL 2.0 specification introduces support for switching, memory pooling, and persistent memory – all while preserving industry investments by supporting full backward compatibility.
An increasing number of applications — ranging from databases to AI workloads — are being enhanced to take advantage of persistent memory. This webinar will explore how the CXL specification has evolved to support persistent memory devices in a way that preserves the established software model. This webinar will cover enhancements to the CXL protocol, error handling, and standardized configuration interface, enabling innovative designs that are based on a variety of non-volatile media and form factors.
Introducing the Compute Express Link™ 2.0 Specification
Airing Date: December 10, 2020
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.

Compute Express Link™ (CXL™): Link-level Integrity and Data Encryption (CXL IDE)
Airing Date: September 30, 2021
Security is a key cornerstone for any technology to be successful and CXL is making great strides in security by working collaboratively with other industry-standard bodies such as PCI-SIG and DMTF to ensure a seamless user experience with the best security mechanisms. CXL 2.0 enhances the security mechanism from CXL 1.1 and 1.0 by adding link-level Integrity and Data Encryption (CXL IDE) to provide confidentiality, integrity and replay protection for data transiting the CXL link.
This webinar will explore CXL IDE usage models and how security is managed across CXL.io, CXL.mem, CXL.cache and CXL Switches. The webinar will also explore a Device’s responsibility to maintain security.
Compute Express Link™ 2.0 Specification: Memory Pooling
Airing Date: March 23, 2021
Compute Express Link™ (CXL™) is an open industry-standard interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between the host processor and devices such as accelerators, memory buffers, and smart I/O devices. In November 2020, the CXL Consortium announced the CXL 2.0 specification which introduces support for switching, memory pooling, and support for persistent memory – all while preserving industry investments by supporting full backward compatibility.
In this webinar, Mahesh Wagh (Intel) and Rick Sodke (Microchip), will explore how CXL 2.0 supports memory pooling for multiple logical devices (MLD) as well as a single logical device with the help of a CXL switch. This presentation will also introduce the standardized fabric manager for inventory and resource allocation to enable easier adoption and management of CXL-based switch and fabric
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 (CXL.io, 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.
