Shhhhh… Deadlocks Anonymous In Session


I am sure there is an anonymous group – like Alcoholics Anonymous – headquartered in Silicon Valley, meeting every quarter to discuss the deadlocks that have paralyzed their products, roadmap and deployments. In discreet venues in every town, small groups of engineers huddle together to share war stories about the disgruntled customers whose trust was lost because of a deadlock discovered o... » read more

The Race To Autonomous Cars


To say that the race for autonomous transportation has been heating up would be a gross understatement. By now all, companies that aim to be leaders, or at least want a piece of the action have already established their presence. Some in a successful way, while others not so much. This is not a race that can be won by sprinting alone. It is a team relay where partnerships have to be formed, ... » read more

The Perfect (Silicon) Marriage… Yes, It Exists


Nope, this is not Dr. Phil masquerading as a tech blogger, trying to penetrate the semiconductor market. I am no Dr. Phil, but today, rather than expound on interconnect IP and how it relates to the various trends, applications, markets, etc., I would like to tell you a story about a relationship and share an experience with one of our customers, a leading manufacturer of autonomous systems. ... » read more

Boldy Go Where No NoC Has Gone Before


Functional safety, at varying degrees of integrity and with or without the ISO 26262, has become a cornerstone of SoCs in many key market segments, not just automotive. And the industry goal is to achieve these reliability levels without sacrificing any PPA and while continually reducing TTM. Go figure! I know, that’s like saying, make me an omelet without breaking eggs. And egg substitute is... » read more

OSDN – On-chip Software Defined Network


You must be mumbling to yourself, “Oh no, not another NoC article! The term NoC is used so loosely in the industry and everybody seem to be claiming they have one, so what more is there to say?” Fair enough, but please indulge me. Actually, there are some wannabe NoCs out there, but very few actually provide a full-fledged network. I submit, a real NoC should implement all the same key d... » read more

Got System Cache?


Similar to the world we live in, a coherent SoC system has truly become a hodgepodge of often conflicting desires, wants, and needs. While some traffic flows are highly sensitive to CAS latency, others have rigid coherent bandwidth requirements, and others are more concerned with “must have” real-time needs to fulfill their tasks. Varying vastly from "must haves" to "best-effort," finding t... » read more

Adapt Or Perish: A Unified Theory Of Coherency


Evolution is a natural process and more importantly a relatively slow process that has eventually got us here, capable of perceiving, analyzing, and handling complex tasks. As our environment, society, and surroundings became more complex we learned how to adapt at a brisk and instantaneous manner, in this melting pot of a heterogeneous world. The evidence can be seen in all ages, from the poli... » read more

From Game Theory To The Unified Theory of Coherency


Adam Smith said that the best result comes from everyone in the group doing what is best for himself. But he’s only half right because the best result would come from everyone in the group doing what is best for himself and the group. If you are wondering where you might have heard this before, it was Russell Crowe playing John Nash in the movie “A Beautiful Mind.” John Nash was an Ame... » read more
