A lot of progress has been made in infrastructure to secure edge nodes in the IoT and to secure communications between edge nodes and gateways, all of which is good and necessary to block manifest evil, but it’s never enough. Perfect security is and always will be an asymptotic goal, so there should always be room for new ideas. To a … Read More

How Not To Be Incoherent
The advantage of working with cache memory is the great boost in performance you can get from working with a local high-speed copy of chunks of data from main memory. The downside is that you are messing with a copy; if another processor happens to be working in a similar area, there is a danger you can get out of sync when reading and writing… Read More
Lighting Up The Cloud
In our rush to imagine a world populated with IoT devices, tech advances at the top end of this ecosystem (the cloud) don’t seem to get much airtime. But this isn’t because they are limited to modest refinements. As one example, there is active technology development in connectivity around fiber-based communications within the… Read More
Auto Introspection
It is an indictment of our irrationality that our cars are now more health-conscious than we are. Increasingly safety-conscious readings of the ISO26262 standard now encourage that safety-critical electronics (anti-lock braking control for example) automatically self-test, not just at power-on but repeatedly as the car… Read More
What’s Driving Real Medical Tech
I just watched a webinar on non-invasive bio-imaging as a way to detect and track disease, which gave me a sense of the way tech progresses in the medical field and makes for a positive counterpoint to my views on medical IoT, at least as envisioned in much of our industry. The webinar, on new approaches to in-vivo imaging was hosted … Read More
Palladium Moves Power (and Temperature) Modeling to the System Level
I had a debate with Steve Carlson of Cadence earlier in the year at the EDPS conference on whether there were really any truly effective solutions for doing power estimation in emulation. I thought there weren’t and he said I was wrong. After attending the Cadence front-end summit last week, I have to admit he has a point.
First, who… Read More
Powering the IoT – Wishful Thinking versus Reality
There’s a lot of discussion these days on IoT applications, architectures, communication, security and more, all very good stuff, but little debate on how these devices will be powered. If you can plug them in, this maybe isn’t an issue (though we may need to think about increased demand on our overstrained power generation infrastructure).… Read More
Cadence Enters the RTL Power Estimation Game
At the Cadence front-end summit last week, Jay Roy presented the Cadence Joules solution for RTL (and gate-level) power estimation. Jay is ex-Apache, so knows his way around RTL power estimation which should make Joules a product to watch. Joules connects very natively to Palladium for power characterization for realistic software… Read More
Optimizing power for wearables
I was at the Cadence front-end summit this week; good conference with lots of interesting information. I’ll start with a panel on optimizing power for wearables. Panelists were Anthony Hill from TI, Fred Jen from Qualcomm, Leah Clark from Broadcom and Jay Roy from Cadence. Panels are generally most entertaining when the panelists… Read More
Why Medical IoT Won’t Take Off
In the wave of enthusiasm surrounding the IoT, medical applications are often held up as an obvious and compelling area where applications cannot fail to succeed. I beg to differ. I think there are two important reasons why almost no such applications will succeed, at least not in the way we seem to be approaching them today.
The first… Read More
