RISC-V Chiplets, Disaggregated Die, and Tiles

Chris Jones, Vice President, Products—September 16, 2021 Scalable High-Performance Computing SoC Design with RISC-V Whether you refer to the design concept as a disaggregated die, tiles, chiplets, or good ol’ multi-chip modules, a growing trend among SoC designers is making the interposer act like a ‘mainboard’ to host multiple chips. Together, these chips form a coherent whole product intended for a specific market and offer

Protocol and Interface Agnostic Universal D2D Controller for HPC and Chiplets

Overview Demand for die-to-die and chip-to-chip interfaces has been growing steadily in the past few years due to new applications in cloud/data centers, AI (training and edge applications), and High-Performance Computing (HPC). The demand is driven by the requirements of high throughput, low latency and low power in these applications. Advances in packaging technology are further helping the adoption of heterogeneous systems with chiplets/known-good-die(KGD) assembly to create solutions that require the evolution of

Webinar: Build Your Next HBM2/2E Chip with SiFive

I have been watching the trend for quite some time now that many advanced FinFET designs today are actually 2.5D systems in package. All of these 2.5D silicon interposer-based designs have high-bandwidth memory (HBM) stacks on board. Often there are multiple memory stacks in both 4-high and 8-high configurations. If you follow what’s been called the “more than Moore” revolution associated with 2.5 and 3D

Chip-to-Chip Communication for Enterprise and Cloud

I recently had the opportunity to attend a SemiWiki webinar entitled “Chip-to-Chip Communication for Enterprise and Cloud”.  The webinar was presented by SiFive and explored chip-to-chip communication strategies for a variety of applications.  In the first part of the webinar, Ketan Mehta, director of SoC IP product marketing at SiFive explored the uses of the Interlaken protocol. This specification has been around since 2007 and SiFive
