Dr. Das Sharma of Intel

ABSTRACT: High-performance workloads demand on-package integration of heterogeneous processing units, on-package memory, and communication infrastructure such as co-packaged optics to meet the demands of the supercomputing landscape.  On-package interconnects are a critical component to deliver the power-efficient performance with the right feature set in this evolving landscape.  Universal Chiplet Interconnect Express (UCIe), is an open industry standard with fully specified stack that comprehends plug-and-play interoperability of chiplets on a package; like the seamless interoperability on board with well-established and successful off-package interconnect standards such PCI Express and Compute Express Link (CXL).  In this talk, we will discuss the usages and key metrics associated with different technology choices in UCIe, both planar and vertical, and how it will evolve going forward.  We will also delve into the challenges and opportunities for chiplets connected through UCIe, including test and debug.
