What’s in a name? We go from ADLINK to IoT.

There’s so much more than meets the eye to ADLINK; perhaps it’s why they’re one of only five Premier partners to Intel…and a likely leader in the coming embedded IoT phenomenon.

Editor’s note: this particular blog is sponsored by ADLINK, but the opinions represented are my own.

[UPDATE 6-26-14 4:57pm: The Intel Intelligent Systems Alliance is now called the Intel Internet of Things Alliance. This change was announced a few months ago by Intel.]

The ‘iceberg analogy’ applied to OEM ADLINK means that there’s much more substance below the water than what’s immediately visible. After more than 20 announcement “blips” on my PR meter recently, I dug a bit deeper into the company that started out in 1995 in test and measurement building A/D/A equipment and boards. (ADLINK meant “the link between analog and digital”.) The public company moved quickly into industrial computing and a steady 20% CAGR.

I know of ADLINK mostly as providing VME, VPX, COM Express, and PC/104 modules for rugged and harsh systems. They bought PC/104 creator Ampro in 2008, bringing that company’s robust COTS innovations in PC/104 and SWAP-C chassis (size, weight, power, cost) under the ADLINK logo. ADLINK is now the world’s second largest PC/104 supplier.

In 2012, ADLINK purchased Europe’s LiPPERT to round out their rugged SBC expertise and get closer to Intel. LiPPERT brought along a device-to-cloud framework (M2M stack, API, BIOS, web server, etc) called Smart Embedded Management Agent (SEMA) that seems ideal for remote control and query of IoT devices. SEMA, it turns out, works with both x86 and ARM—the architectures that will likely dominate the emerging IoT.

These acquisitions proved that rugged, of course, applies to lots of places besides mil/aero and defense; for example, automotive, transportation (mass transit), medical, industrial, and energy. Upon my closer inspection, I found the ADLINK ‘iceberg’ revealed products and customer testimonials in all of these markets, plus a pattern of innovation and unique intellectual property (IP) like SEMA.

This unique IP isn’t found at most of ADLINK’s competitors: I see it setting the stage for ADLINK’s morphing into an IoT/M2M systems supplier.

Not Buzzed on IoT

Fads evolve quickly, and the Internet of Things was M2M last year, and before that it started as Intel’s Intelligent Systems. (Intelligent Systems is also the name of the Alliance of which ADLINK is a Premier Member.)

Pull quote ADLINKIntel merely invented the phrase that envisioned millions of connected embedded systems—some with intelligence, some merely as endpoint sensors. Two key points: 1. Intel was bang-on correct that IoT is no mere fad but a fundamental, sustainable market shift; and 2. I believe ADLINK is supremely well positioned to capitalize on the IoT.

Intel has bets on the IoT in more places than I can list here, from Core, Atom and Quark CPUs and SoCs, to Wind River Intelligent Device Platform, to McAfee’s Embedded Security. Alphabet soup, for sure, but Intel also relies on partners—Premier Partners, those that are privy to Intel’s own iceberg—to round out the IoT ecosystem.

The collection of press releases I’ve received year-to-date point to ADLINK’s complete ‘iceberg’ for the IoT.

The company has hardware, software and systems that touch all of the following: sensor, endpoint note, IoT gateway, network/cloud communications, remote diagnostics, boards/chassis/systems, and demo/application code. And a deep knowledge of how to build rugged, survivable systems.

Over the next several months, I’ll be exploring and sharing with you ADLINK’s technology and IP for the embedded IoT and cloud.

You’ll see that the company’s technology ‘iceberg’ extends well below the water line.

 

Efficient Signal Switches are Today’s Digital Traffic Cops

Betcha your next embedded design has or needs a signal switch. Here’s a snapshot of what to look for. The devil’s in the details.

Editor’s note: This particular blog is sponsored by Pericom.

Like a traffic cop, signal switches route GHz data quickly and efficiently. (Courtesy: Wiki Commons.)

Planning for an upcoming vacation, I got to thinking about big cities at rush hour. An experienced policeman with a whistle and urgent hand signals can route traffic at busy 4-, 5- even 8-way intersections efficiently with little delay and no pile-ups.

At first glance, there’s nothing sexy about a traffic cop in uniform and helmet moving all those cars across the intersection.

But the efficiency with which it’s done is elegant poetry: timed perfectly, no collisions, and cars get from point A to point B quickly (and they never have to reverse course). Signal switches are the same thing. Not terribly exciting on the surface, but one has to appreciate their elegance and efficiency.

Pull quoteSo it is with a modern digital signal switch. In darned near every embedded system you’ve got all these USB hubs, PCI root complexes, multi-board backplanes, multi-page/bank memories, and PCIe-to-“GHz” digital channels interoperating and passing data.  And they all need signal switches of some sort. The switch is a one-to-many MUX, it moves data in a non-blocking way, and it neither throttles nor degrades the signals as they pass through the ports.

The key parameters of signal switches are:

  • high-speed throughput,
  • maximum signal integrity and low insertion loss,
  • flexible fanout (x inputs to y outputs), and
  • adherence to standards like USB 2.0/3.0, PCI Express, 10/100/1G Ethernet, and others.

Heavy_Switch_1I’m gaining a new appreciation for traffic cops and signal switches. Consider perhaps the simplest example of how a switch is used and how its parameters matter. The PCIe 3.0 2:1 MUX shown below routes a single input (of 2 channels) to two outputs (of 2 channels). Think of a big, clunky hard-wired A-B rotary switch and you get the idea. Simple, right?

PCIe 3.0 MUXThis kind of switch is commonly used to bridge different PCIe busses on the same card, or connect/enable different backplane slot cards, or move data between on- and off-card (mezzanine?) resources. In other words: it’s used in lots of places.

But PCIe 3.0 is based on differential, LVDS signals running 8B/10B encoding and moving data at an RF-like 8 Gb/s (8 giga-transfers/sec, to be precise). At this frequency, signals degrade, are attenuated, reflect and bounce around, and the signal “eye” can easily close—meaning poor speed and signal integrity; so much so that the signals may not even resemble PCIe at the output ports. So our “simple” MUX signal switch needs to move the data quickly, cleanly, and appear to the host/targets as if it wasn’t even there!

Switches like the PI3PCIE3212 from Pericom Semiconductor, have covered all the details, freeing designers to map their signal architecture without worrying about the nuances. What about all those dB numbers @ frequency in the figure? They add up to hassle-free designs and signals that move from A-to-B without any designer thought.

Sort of like cars at a busy intersection. When that cop is there waving his hand, data traffic is under control and moves smoothly. Your signal switch behaves similarly.

TI emphasizes “KISS” in new Wi-Fi ICs

Low cost is a “given”; TI instead focuses on the “simple, stupid” part of the connected IoT.  New Internet-on-a-chip Wi-Fi ICs.

By: Chris A. Ciufo

Hey, this IoT thing has got me really stoked. As a long-time geek, I’ve been hard-wiring automated stuff since I was a kid. Surrounded by my app-enabled Xfinity CATV and my AirPlay-connected home theater, I’m anxious to add some door cams, a remote controlled overhead garage door, basement temperature and flood sensors, and…so much more!

But if every embedded sensor, doodad, HVAC and industrial machine on the planet is to be connected to the Internet—which is the goal of the Internet of Things/Everything (IoT)—the ICs to connect them have got to be cheap. As in a couple of bucks per connection in high volume.

But more importantly, it’s got to be easy for non-RF designers to add Wi-Fi into their products. Can you imagine if every 110VAC replacement plug from Home Depot had built-in Wi-Fi? I’d pay $5-10 for one of those. How about a light switch? Ceiling fan? The office shredder? The burbling Zen water feature on the receptionist’s desk?

Most of these embedded “wannabe nodes” were created by engineers who’ve never before designed with Wi-Fi. Nor do they understand the hundreds of APIs needed for the most basic TCP/IP connection.

Or: how likely is it that designers have experience with IoT security requiring lock down to protect factory automation or your nanny cam? Forget it; Wi-Fi’s 3AES and the Internet’s TLS/SSL security is more complicated than the whole device itself!

TI is embedding new “Internet on-a-Chip” Wi-Fi ICs with the KISS principle: keep it simple, stupid. But price matters, too.

TI’s SimpleLink is “Internet on a Chip”

Available “with” (CC3200) or “without” (CC3100) an embedded ARM Cortex A4 MCU to run apps like email, SMS or a web server, TI’s new all-in-one SimpleLink Wi-Fi ICs make easy for designers all that complicated Wi-Fi and Internet stuff.  They’re easy on price so the “cheap” part is covered. The CC3100 is $6.70 @ 1KU; the CC3200 is about $8.00 for 1,000.

Keeping in mind “KISS”, according to Dana Myers, Channel Marketing and Product Manager for TI’s Wireless Connectivity Group, the company recognizes how difficult Wi-Fi can be to design into a system. If the IoT is ever to find its way into the all-around-us devices mentioned above, the design-in process must be easy.

According to Myers, “TI has done the hard work for designers.” For example, a mere one API is needed to handle Internet security protocols (versus “hundreds” if hand coded). Further examples of how TI has dramatically simplified things are shown in below.

Better than IEEE 802.15.4 and BLE

If Wi-Fi is to be the “last mile” of cloud connectedness to the IoT’s billions of devices, it will have to displace other wireless technologies. The collection of IEEE 802.15.4 “personal” network standards that include ZigBee and 6LoWPAN—plus the newer Bluetooth Low Energy standard (BLE)—are not competition for Wi-Fi.

“The reason,” said TI’s Myers, “is that Wi-Fi is already installed in most locations where the devices are.” And the 802.15.4 and BLE standards are reserved for “personal range” lower rate connectivity than Wi-Fi. And while most IoT sensors will wake from sleep and broadcast only small burst packets (in other words: not much M2M data), some IoT devices may consume loads of bandwidth. Wi-Fi’s advantage then is that it is low cost, ubiquitous, has long range, and is a fat pipe.

Yet Wi-Fi’s Achilles Heel has been its power consumption. Just look at your 4-hour connected laptop to convince yourself of how much power connectivity can burn.

One Year on Two “AA” Batteries

Besides making Wi-Fi cheap and easy, TI will make it long-lasting, too. The company states the intention of “bringing Wi-Fi power to a new low” with a year’s worth of connectivity on just two AA alkaline batteries.

The “always connected” use case (left, Figure below) shows 125 μA sleep current while still connected to the network. This is possible for up to 2 seconds at a time between Wi-Fi beacons (20x better), versus the typical 100 ms sleep period. While awake, the CC3100 Internet on-a-Chip burns a mere 37 mA awaiting Rx beacon reception.

Boasting a year’s worth of battery life on two alkaline AA batteries, the CC3100 and CC3200 employ some slick power conservation modes. Note: in the left-hand figure, the sleep current is 125 uA (not 120 uA) according to a TI spokeswoman. (Courtesy: TI.)

In true M2M sensor mode, an “intermittently connected” node will burn just 4 μA in hibernation, requiring only 95 ms to wake up and establish a secure Wi-Fi connection. Add another 105 ms onto that and the network processor IC has established a secure TLS connection to the Internet.

All of these numbers—power consumption, sleep and hibernation current, and time to establish cloud connectivity—are impressive.

An Entire Ecosystem of SDKs, HDKs, Apps

Since the goal with these new devices is simplicity for designers, TI is making available both Launchpad (base cards with MCUs) and BoosterPack (mezzanine cards with I/O), plus over 30 sample applications. Apps range from email and SMS, to an integrated web server. Other applications are possible.

TI has also partnered with cloud aggregators like Exosite, IBM, Xively and others. This assures “big data” remote manageability of M2M notes and communication with the CC3100 and CC3200 ICs. When asked if TI plans on releasing its own MQTT protocol and cloud dashboard, the TI spokeswoman merely replied “no plans, right now”.

But at the rate TI’s going by pushing down the barriers to Wi-Fi connectivity—in price, simplicity, ease-of-use, and security—it’s only a matter of time before the company adds more SimpleLink goodies.

They’re really following the “KISS” principle.

Part 2: LynuxWorks becomes Lynx Software Technologies

LynuxWorks reboots to real time roots as “Lynux Software Technologies”.

In this Part 2 of 3, I editorialize three companies in the embedded market that are changing or enhancing their strategies. What you need to know…and why they’re doing it.

Lynx Software logoFor 25 years the company that created LynxOS has focused on real-time software for embedded systems. Successfully fending off RTOS challenges from Green Hills (INTEGRITY), Wind River Systems (VxWorks), Ready Systems (VRTX), and ISSI (pSOS), Lynx Real Time Systems has held its own and evolved with the times.

Once again the company is evolving: this time, the company is re-emphasizing the RTOS market with a nod to recent design win success in safety and security products. And like everyone else, they’ve announced an Internet-of-Things (IoT) initiative.

The New Old Focus

Company CEO Gurjot Singh explains the name change to “Lynx Software Technologies” this way: the new name “offers the best representation of the company’s forward direction” with products like LynxOS and LynxSecure. Both play well with the company’s core customers in mil/aero and safety-critical markets. As well, LynxSecure and ancillary products like a certifiable network stack have a strong play in the evolving embedded Internet of Things (IoT) movement.

The company’s core five markets are: Defense, Avionics, IoT, Cyber Security, and general Embedded (Figure 1).

Figure 1: The new Lynx Software Technologies (company) will focus on the five areas shown here.

Figure 1: The new Lynx Software Technologies (company) will focus on the five areas shown here.

As competitors like VRTX and pSOS came and went, LynxOS continued winning designs in deterministic, hard real-time systems. But as the market for Linux ballooned and even the company’s core defense and aerospace customers embraced the COTS goodness in Linux, Lynx Real Time Systems jumped on the open source movement.

Renamed years ago to “LynuxWorks” to give credibility to Linux, the company introduced BlueCat Linux and BlueCat RT products, while still maintaining the RTOS called LynxOS.  Competitors like Wind River Systems (now owned by Intel) were slower to embrace Linux and (initially) paid a price in design wins for lagging the market.

Today’s Announcement: Goodbye Linux

By removing the wordplay “Lynux” in the company name, Lynx Software Technologies clearly demonstrates the re-emphasis on its hard real time products like LynxOS (which it fortunately never gave up), LynxOS-178, and LynxSecure Separation Kernel Hypervisor (Figure 2).

Figure 2: Lynx Software Technologies will focus on these real-time software products.

Figure 2: Lynx Software Technologies will focus on these real-time software products.

According to marketing VP Robert Day, “We’re definitely de-emphasizing [our] Linux products.” As a long lifecycle defense and transportation software provider, Lynx Software (the company) plans to support Linux design wins for all customers as contractually promised.

By moving away from the “free distribution/money-by-maintenance” model, the company firmly asserts that profits will come from their proprietary products through traditional software licensing models. It’s a cleaner approach that customers understand.

Where To From Here?

In essence, the company will build its future on a single product: the LynxSecure separation kernel. Now at version 5.2, the certifiable kernel spawns multiple products. The original LynxOS—now in version 7.0—is targeted at deterministic embedded systems but with a new twist. Security features for networked Internet-of-Things (IoT) devices and gateways include IPv6, IPSec, OpenSSL/SSH, TCP wrappers and more. LynxOS remains viable for symmetric multiprocessing (SMP) designs.

LynxOS-178 is the FAA certifiable version of the OS and has won DO-178B designs in avionics and other applications, said marketing VP Robert Day.

My Take on This

In a discussion with Lynx Software’s Robert Day recently, I gave the company high marks for sticking to its core technology: real-time operating systems. As well, I remember when in 2004 the company started a forklift upgrade on it’s “POSIX-conformant” underpinnings to bolt in a new, certifiable separation kernel.

At the time, the notion of running insecure guest operating systems atop an unassailable RTOS kernel had been pioneered as a COTS product by (as I recall) OnCore Software (now defunct). LynuxWorks and Green Hills Software both announced they would follow this approach; Wind River later followed.

Today, running Linux, Windows, Android and other OSes atop a hypervisor architecture is the accepted approach in mission- and safety-critical environments. The automotive industry is moving in this direction, lead by QNX, Wind River, and others.

Lynx Software Technologies is in a good market position, with defensible IP, secure (and certified) design wins, and a core strategy that plays well to their strengths in mil/aero and the emerging Wild West connected IoT market.

 

 

 

 

Google adverts on your IoT display?

How long until you get a Google advertisement on your thermostat or car IVI display?

The Internet of Things (IoT) is real and will for sure connect all manner of devices and silent embedded systems. Your Philips Hue light bulbs, your Samsung refrigerator, your front door lock, your baby cam, and soon your car.

A platform for future adverts?

But Google, who owns Nest–the App-controlled thermostat darling of CES 2013–might well “monetize” anything that runs Android.  Though a spokesperson tells Engadget.com that’s not in the cards now, Google has made a successful business out of mining gold from its products by using customer data to target advertising.

A recent Engadget article “Google ads could be coming to thermostats, refrigerators and car dashboards (update)” muses over this possibility.

gmail4Recall that Gmail was launched many years ago not out of Google’s altruism, but as a platform to examine your email and serve up targeted ads in a browser window. (Indeed, if you read Google in a browser, you’ll see ads on the right-hand side. Those ads are based upon the content of your email.)

In fact, one might argue that Google is the original user of “big data”: the company was founded on that principle.

So as the Internet of Things spreads to more connected devices, if they have a screen, you can be sure someone (maybe Google) is going to look to make some money on that LCD real estate.
