CXL Thriving As Memory Link


CXL is emerging from a jumble of interconnect standards as a predictable way to connect memory to various processing elements, as well as to share memory resources within a data center. Compute Express Link is built on a PCI Express foundation and supported by nearly all the major chip companies. It is used to link CPUs, GPUs, FPGAs, and other purpose-built accelerators using serial communic... » read more

Which Chip Interconnect Protocol Is Better?


Semiconductor Engineering sat down to the discuss the pros and cons of the Compute Express Link (CXL) and the Cache Coherent Interconnect for Accelerators (CCIX) with Kurt Shuler, vice president of marketing at Arteris IP; Richard Solomon, technical marketing manager for PCI Express controller IP at Synopsys; and Jitendra Mohan, CEO of Astera Labs. What follows are excerpts of that conversation... » read more

Conflicting Goals In Data Centers


Two conflicting goals are emerging inside of data centers—speed at any cost, and the ability to extend hardware well beyond its expected lifetime to amortize that cost. Layered across both of those are concerns about how to move data back and forth more efficiently, how to secure it, and how to best integrate different generations of technology. But these widely different goals have create... » read more
