Cxl packets
Compute Express Link (CXL) is an open standard for high-speed, high capacity central processing unit (CPU)-to-device and CPU-to-memory connections, designed for high performance data center computers. CXL is built on the serial PCI Express (PCIe) physical and electrical interface and includes … See more The CXL technology was primarily developed by Intel. The CXL Consortium was formed in March 2024 by founding members Alibaba Group, Cisco Systems, Dell EMC, Meta, Google, Hewlett Packard Enterprise See more The CXL standard defines three separate protocols: • CXL.io - based on PCIe 5.0 with a few enhancements, it provides configuration, link initialization and management, device discovery and enumeration, interrupts, DMA, and register … See more In May 2024 the first 512GB devices became available with 4 times more storage than previous devices.[1] See more • Coherent Accelerator Processor Interface (CAPI) • Universal Chiplet Interconnect express (UCIe) • Data processing unit (DPU) See more CXL is designed to support three primary device types: • Type 1 (CXL.io and CXL.cache) – specialised accelerators (such as smart NIC) … See more DDR when installed into DIMMs have superior latencies (typically 20ns) as compared to DDR when installed in CXL devices (typically 200ns) See more • Official website See more Web• CXL.memory • CXL.io CXL cache and memory stack is optimized for latency: • Separate transaction and link layer from IO • Fixed message framing CXL io flows pass through a stack that is largely identical a standard PCIe stack: • Dynamic framing • Transaction Layer Packet (TLP)/Data Link Layer Packet (DLLP) encapsulated in CXL flits
