OVERVIEW
The massive growth in the production and consumption of data, particularly unstructured data, like images, digitized speech, and video, results in an enormous increase in accelerators' usage. The growing trend towards heterogeneous computing in the data center means that, increasingly, different processors and co-processors must work together efficiently, while sharing memory and utilizing caches for data sharing. Hence sharing memory with a cache brings a formidable technical challenge known as coherency; which is addressed by the Compute Express Link (CXL).
WHAT IS CXL?
CXL is a technology that enables high-bandwidth, low-latency connectivity between the host processor and devices such as accelerators, memory buffers, and smart
