Who Really Needs USB 3.1?

Who Really Needs USB 3.1?
by Eric Esteve on 10-29-2014 at 4:58 am

USB is certainly the most ubiquitous of the Interface protocols. I would bet that everybody is using USB everyday (I mean activate a USB connection, as we also use PCIe or SATA even if we don’t realize that we do it), but which application will get benefit of the 10 Gbps delivered by USB 3.1? Before precisely answering the question, … Read More


G.fast on the copper quick road for broadband

G.fast on the copper quick road for broadband
by Don Dingee on 10-28-2014 at 3:00 pm

After a four year gestation period typical of global communications standards, G.fast has reached the point where chipset makers can implement parts against stable specifications. Formal approval of the physical layer spec, G.9701, is expected by the end of 2014. G.9700, dealing with power spectral density issues, was approved… Read More


Sensing, Processing and Connecting: IoT Fundamentals

Sensing, Processing and Connecting: IoT Fundamentals
by Eric Esteve on 10-25-2014 at 7:00 am

Internet of Things, or Internet of Everything, is certainly the buzzword of the year. Does IoT describe one product family? Not really as the acronym describes a family of concepts, each of these concepts could effectively be turned into a family of products, if this concept reach the market, or fulfill a market need. Nevertheless… Read More


SecureCore: secure MPU for IoT

SecureCore: secure MPU for IoT
by Eric Esteve on 10-22-2014 at 8:44 am

The evaluation of the number of connected (IoT) systems by 2020 varies depending on the source, but we should see in the range of 30 billion IoT devices by that date. We already know some of the basic requirements: such a device will have to be connected, low cost, ultra-low power and… secure. The first three are key enablers, but we … Read More


How Lucio Lanza Got Into EDA

How Lucio Lanza Got Into EDA
by Paul McLellan on 10-21-2014 at 7:01 am

Lucio Lanza is this year’s recipient of the Kaufman award. Unlike most recipients, Lucio worked closely with Phil Kaufman earlier in his career. I met with him at his office in Palo Alto to hear the story.

Even if you have never met him, it would be a reasonable guess from his name that Lucio Lanza is Italian. And you’d be right. He grew… Read More


MIPI Soundwire IP Sounds Innovative

MIPI Soundwire IP Sounds Innovative
by Eric Esteve on 10-19-2014 at 3:07 am

MIPI SoundWire specification will be integrated into mobiles systems, like smartphone or media tablet. In fact some of the well-known chip makers have already decided to integrate MIPI SoundWire into their last application processor release. MIPI SoundWire is also the type of specification which could be used in many other … Read More


Linux and the ARC of the Coherent

Linux and the ARC of the Coherent
by Don Dingee on 10-18-2014 at 7:00 am

Remember that thing called “real-time Linux”? Yeah, nobody else does either. As builds became configurable and clock speeds increased, embedded Linux manifested itself as fast enough for many applications – if a few other SoC details are addressed.

Most obvious for SoCs to run Linux is the need for a fully integrated MMU implementation.… Read More

Demler: Quad Core is Just For Marketing; Intel Will Not Succeed in Mobile
by Paul McLellan on 10-15-2014 at 9:00 pm

At Memcon today Mike Demler of the Linley Group (and coincidentally someone who used to work for me back at Cadence and who now run Memcon, small world) gave an interesting presentation on Trends in Mobile Processors. A mobile application processor (AP) is a highly integrated SoC to run the applications in a mobile device. Mostly… Read More


Did we forget non-volatile memory?

Did we forget non-volatile memory?
by Don Dingee on 10-15-2014 at 7:00 pm

In our rush to shrink SoC nodes more and more to achieve better performance and more complex devices, we may have forgotten a passenger in the back seat: non-volatile memory. There has been little discussion of this in the pages of SemiWiki until now. Let’s give it a closer look.

Embedded flash has usually been associated with microcontrollers,… Read More

GPU Benchmarks? Try to See the Complete Picture…
by Eric Esteve on 10-15-2014 at 3:29 am

We all know benchmarks, but do we really understand benchmark results? Benchmark users should always look beyond the simple score when making in-depth technical analysis and request to see all the facts. There are many graphics benchmarks to choose from but let’s name today these three below:

3DMark Ice Stormfrom Futuremark… Read More
