There are two camps of thinking on the IoT: those who believe Bluetooth and Wi-Fi rule the edge, and those who support any of dozens of other wireless networking specifications for their various technical advantages. The ubiquity of Wi-Fi in homes helps devices connect in a few clicks – so why don’t more IoT designers use it?… Read More

Fit-for-purpose IoT ASICs are about more than cost
We’ve been saying for a while that it looks like there is a resurgence in design starts for ASICs targeting the IoT. A recent webinar featuring speakers from ARM and Open Silicon (and moderated by Daniel Nenni) affirms this trend, and provides some insight on how these designs may differ from typical microcontrollers.
One of my first… Read More
To err is runtime; to manage, NoC
Software abstraction is a huge benefit of a network-on-chip (NoC), but with flexibility comes the potential for runtime errors. Improper addresses and illegal commands can generate unexpected behavior. Timeouts can occur on congested paths. Security violations can arise from oblivious or malicious access attempts.
Runtime… Read More
System Design: Turtles All the Way Down
According to Steven Hawking, Bertrand Russell once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun orbits around our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: “What you have told us is rubbish. The world is really a flat plate supported… Read More
Compositions allow NoCs to connect easier
I blame it on Henry Ford, William Levitt, and the NY State Board of Regents, among others. We went through a phase with this irresistible urge to stamp out blocks of sameness, creating mass produced clones of everything from cars to houses to students.
Thank goodness, that’s pretty much over. The thinking of simplifying system design… Read More
So, where are all the EMBEDDED guys?
Roaming the aisles at #50DAC the past week left me with one unmistakable impression: there were two shows going on at the same time. Oh, we were all packed into one space together at the Austin Convention Center and neighboring hotels. But we weren’t quite all speaking the same language – yet.… Read More
Smart mobile SoCs: Made in China
One of the comments to previous installments of this series was that there isn’t much left for the merchant suppliers of smart mobile SoCs, considering Apple and Samsung have majority share and design their own parts. The theory is this makes it hard for many suppliers to continue investing at the resource levels needed to bring … Read More
While you’re reading the SoC manual
There was a day, not too long ago, when a software developer could be intimate with a processor through understanding its register set. Before coding, developers would reach for a manual, digging through pages and pages of 1s and 0s with defined functions to find how to gain control over the processor and its capability. One bit set… Read More
