Paper Title: CXL: A Basic Tutorial

Paper Abstract: Highly popular emerging applications and technologies such as AI, ML, and persistent memory demand ever-higher bandwidth and ever-lower latency. The CXL interface is a new standard designed to meet such needs by providing extremely high-speed connections for remote processors, memory expansion units, and accelerators. CXL is scalable, extensible, and flexible, and provides for both cache coherency and limited traffic on the memory bus. It uses the established PCIe 5.0 technology as its current physical interface, but allows for even higher-speed future connections.
