Automotive AI Hardware: A New Breed


Arteris IP functional safety manager Stefano Lorenzini recently presented “Automotive Systems-on-Chip (SoCs) with AI/ML and Functional Safety” at the Linley Processor Conference. A main point of the presentation was that conventional wisdom on AI hardware markets is binary. There’s AI in the cloud: Big, power-hungry, general-purpose. And there’s AI at the edge: Small, low power, limited... » read more

NoCs In Authoritative MPSoC Reference


The MPSoC Forum, sponsored by IEEE and other industry associations, hosts an annual conference in beautiful places around the planet. It is dedicated to showcasing renowned academic and industry experts in multicore and multiprocessor architectures. The goal is to explore trends in system-on-chip (SoC) hardware and software architectures and applications. An additional purpose is to consider th... » read more

Steep Spike For Chip Complexity And Unknowns


Cramming more and different kinds of processors and memories onto a die or into a package is causing the number of unknowns and the complexity of those designs to skyrocket. There are good reasons for combining all of these different devices into an SoC or advanced package. They increase functionality and can offer big improvements in performance and power that are no longer available just b... » read more

Interconnects In A Domain-Specific World


Moving data around is probably the least interesting aspect of system design, but it is one of three legs that defines the key performance indicators (KPI) for a system. Computation, memory, and interconnect all need to be balanced. Otherwise, resources are wasted and performance is lost. The problem is that the interconnect is rarely seen as a contributor to system functionality. It is seen... » read more

SoC Integration Complexity: Size Doesn’t (Always) Matter


It’s common when talking about complexity in systems-on-chip (SoCs) to haul out monster examples: application processors, giant AI chips, and the like. Breaking with that tradition, consider an internet of things (IoT) design, which can still challenge engineers with plenty of complexity in architecture and integration. This complexity springs from two drivers: very low power consumption, eve... » read more

Application Driven Network-on Chip Architecture Exploration & Refinement for a Complex SoC


Peer-reviewed technical journal article from Springer's "Design Automation for Embedded Systems Journal."  Summarizes the various features a NoC is required to implement to be integrated in modern SoCs. Describes a top-down approach, based on the progressive refinement of the NoC description from its functional specification (Sect. 4) to its verification (Sect. 8) Click here to read more. ... » read more

Scramble For The White Space


Chipmakers are pushing to utilize more of the unused portion of a design for different functions, reducing margin in the rest of the chip to more clearly define that white space. White space typically is used to relieve back-end routing congestion before all of the silicon area is used up. But a significant amount of space still remain unused. That provides an opportunity for inserting monit... » read more

The Role Of NoCs In System-Level Services


The primary objective of any network-on-chip (NoC) interconnect is to move data around a chip as efficiently as possible with as little impact as possible on design closure while meeting or exceeding key design metrics (PPA, etc.). These networks have become the central nervous system of SoCs and are starting to play a larger role in system-level services like quality of service (QoS), debug, p... » read more

Designing For Extreme Low Power


There are several techniques available for low power design, but whenever a nanowatt or picojoule matters, all available methods must be used. Some of the necessary techniques are different from those used for high-end designs. Others have been lost over time because their impact was considered too small, or not worth the additional design effort. But for devices that last a lifetime on a si... » read more

An Automotive Value Chain In Flux


When companies view suppliers from inside their specialized niches, it is tempting to imagine the business world will continue as-is, with just minimal improvements each year. But in the automotive value chain, this no longer holds. The rapid pace of innovation around intelligent systems in cars is disrupting the business flow. Back in simpler times, semiconductor companies would work with Tier... » read more
