Generative artificial intelligence (AI) requires rapid and continuous movement of large amounts of data. In a growing number of instances, electrical input/output (I/O) connections between the ICs in chiplets are becoming a bottleneck to higher performance. Key electrical I/O performance barriers include power efficiency, bandwidth, and latency. This FAQ looks at the anticipated benefits of […]
FAQ
How can carbon nanotubes improve interconnect performance?
Carbon nanotubes (CNTs) have been proposed for reducing fretting wear in connectors used in high-vibration environments like vehicles. They can also be used to make contacts with lower contact resistance and higher corrosion resistance compared with silver (Ag) plating, and they have been used to reduce the weight in some shielded cables by 25% or […]
Delivering power supply reliability in mission-critical systems
There are several factors to consider when selecting a power supply that delivers the high voltages often needed by large and complex high-performance systems. For almost all electronic products and systems, high reliability should be expected. Still, in some markets, reliability cannot be compromised or a trade-off for other performance factors. In particular, mission-critical industrial […]
How do UCIe and BoW interconnects support generative AI on chiplets?
The bunch-of-wires (BoW) and Universal Chiplet Interconnect Express (UCIe) standards provide designers with tradeoffs in terms of throughput, interconnect density, delay, and bump pitch. This FAQ compares the performance of BoW and UCIe and looks at how optical interconnects may provide a path to even higher performance interconnects in chiplets. To realize optimal performance for […]
What is the heterogeneous integration roadmap, and how does it support generative AI?
The heterogeneous integration roadmap (HIR) is an ongoing initiative of the IEEE Electronics Packaging Society. It’s a living document that continues to evolve and expand in response to technological developments like the growth of generative artificial intelligence (AI) and quantum computing. This FAQ starts with a brief overview of heterogeneous integration, looks at the scope […]
How to separate differential and common-mode harmonic noise currents
Differential-mode and common-mode currents can cause your product to produce radiated and conducted emissions. These three techniques can help you measure them.
How does the open domain-specific architecture relate to chiplets and generative AI?
The Open Domain-Specific Architecture (ODSA) is a project within the Open Compute Project (OCP) community to establish open physical and logical die-to-die (D2D) interfaces for chiplets. The goal is to democratize the design and use of chiplets for domain-specific high-performance computing (HPC) applications like generative artificial intelligence (AI). Domain-specific architectures (DSAs) are an emerging approach […]
How do heterogeneous integration and chiplets support generative AI?
Chiplets are here, and more are coming. They can overcome the yield limitations of large ASICs, support a mix-and-match strategy for heterogeneous semiconductor IPs and multiple process nodes, improve thermal performance, and speed time to market. They are being used in a range of high-performance computing (HPC) applications, notably generative artificial intelligence (AI) and machine […]
What quantum sensors can be used as GPS replacements?
There’s a variety of quantum sensors available for use as a global positioning system (GPS) replacement including quantum compasses, atomic gyroscopes, and atom interferometers. Several options for a quantum GPS replacement, also called quantum position sensing (QPS), are being developed. Three examples include quantum active navigation that overlays and supplements existing satellite-based GPS systems, quantum […]
How to raise awareness for the necessity of carbon monoxide sensors
Public outcries for reducing carbon dioxide (CO2) emissions to reduce their climate change impact have been widely promoted for more than two decades. However, attention to a more immediate public health problem from carbon monoxide (CO) has not received anywhere near the same level of attention– unless the deaths get news covered. For example, in […]
