Compute Express Link (CXL)
Compute Express Link (CXL) is a new high-speed CPU-to-Device and CPU-to-Memory interconnect designed to accelerate next-generation data center performance. 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 based on a PCI Express 5.0 Physical layer with speeds up to 32GT/s. Teledyne LeCroy provides protocol analysis test equipment to support development and debug of CXL based devices.
