Rambus’s AES Crypto IP Resists DPA Attacks
“Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke
You have got to be kidding me. I mean, I’m an engineer. I know how stuff works. And you’re telling me you can somehow snag my computer’s encryption keys out of thin air? No way. No. @%$#-ing. Way.
I’ve seen it happen. I didn’t believe it at first, but there’s nothing quite like a live demonstration to make you a convert. It’s time to stock up on tinfoil hats. Here’s the background: Practically every computer, cell phone, tablet, cable TV decoder, satellite box, smartcard, modern passport, or other gizmo uses encryption in some way.
EE Journal Turns 11
We live and work in an amazing time. The global community of electronic engineers has created the greatest leap of technological progress in human history. In the almost fifty years that Moore's Law has existed, the number of transistors we can put on a single chip has risen from fifty to somewhere around twenty billion. That is a truly amazing achievement. And the power of that almost unimaginable feat has rippled and ripped through just about every aspect of our lives and our culture.
As the creators of that change, we have faced a unique challenge. While the rest of the world gets to enjoy the fact that electronic technology doubles in capability every two years, electronic engineers are faced with the harsh reality that we have to double our own productivity on that same schedule. Moore's Law becomes our mandate. I am aware of no other profession that requires a constant exponential improvement in worker productivity just to stay in the game.
Vesper Announces Piezoelectric Microphones
Microphones are not for the faint of heart. There is a sordid history of MEMS microphones, replete with big companies crying “Uncle!” and with legal vitriol.
Unlike something as “simple” as an accelerometer (with apologies to anyone that’s worked damned hard on a fine accelerometer), there’s been less rush to compete once everyone figured out how hard microphones can be.
And so we have a few deeply entrenched incumbents manning the sound.
But microphones still look interesting as an opportunity. We saw some time ago that multiple microphones are becoming a thing. Why? For the same reason that high-quality sound recording uses them. By recording an orchestra and the audience with two mikes, for example, you now have two tracks, and you can subtract the audience track from the orchestra track to get a cleaner version of the orchestra.
Valencell’s Biometric Testing Takes IoT Out for a Spin
This here twin-turbo EEJournal.com podcastin’ hot rod is headed to the IoT finish line - one biometric at a time. In this week’s Fish Fry, we investigate biometric data sensors and how one company is making sure that our fitness is actually what we think it is. My guest is Valencell President Steven LeBoeuf. Steven and I are going to chat about the future of the wearable market, precision biometrics, Valencell’s new state-of-the-art sports testing lab, and a little bit about professional cartooning. Get your wearable motor runnin' folks!
Power, Sensors, Clock Trees, Multicore and Compression Algorithms
September, at least in the Northern Hemisphere, is often seen as the real start of the year. Companies are returning from their summer holidays and revving up with new promotional activities and, particularly in even numbered years in Europe, starting to work towards the huge techno-fest that is electronica in Munich in November. Now this may be a very interesting observation, but why is this relevant? Well, in the last few weeks, I have been exposed to a raft of interesting things, many of which would be worth a whole article in their own right, but, given the limitations of space and time, I have decided to bundle together several different stories from across a wide spectrum of electronics.
Much of what is written in the electronics media concentrates on digital chips and their design and manufacture. We are probably as guilty as most in focusing on these areas, but, after designs have been implemented in these ever-more-challenging process nodes, the chips have to go onto a board, and then they require power.
Synopsys ARC HS38 Processor Has An Embarrassment of Options
It’s a good month for microprocessor aficionados, what with the new Cortus twins, the MIPS I6400, AMD’s Hierofalcon, and now Synopsys’s ARC HS38. There’s still some differentiation to be had in this market.
Followers of Synopsys know that the EDA company acquired ARC, the CPU-design firm, several years ago and folded the CPU IP into its DesignWare library system. Indeed, the processor cores are branded as DesignWare, reflecting the reality that ARC processors are more like a design tool than a traditional CPU core. That’s because ARC processors are user-defined. You can add and subtract registers, create your own instructions, invent new condition codes, bolt on in-house coprocessors, and more. Every ARC processor has the capability to be unique and oh-so-finely tuned to its intended application, a feature that many developers really like. It must be working: ARC cores have appeared in 1.5 billion chips just in this year alone.
