Here’s a sneak preview of June 2018 Circuit Cellar:

PCB DESIGN AND POWER: MAKING SMART CHOICES

PCB Design and Verification
PCB design tools and methods continue to evolve as they race to keep pace with faster, highly integrated electronics. Automated, rules-based chip placement is getting more sophisticated and leveraging AI in interesting ways. And supply chains are linking tighter with PCB design processes. Circuit Cellar Chief Editor Jeff Child looks at the latest PCB design and verification tools and technologies.

PCB Ground Planes
Tricky design decisions crop up when you’re faced with crafting a printed circuit board (PCB) for any complex system—and many of them involve the ground plane. There is dealing with noisy components and deciding between a common ground plane or separate ones—and that’s just the tip of the iceberg. Robert Lacoste shares his insights on the topic, examining the physics, simulation tools and design examples of ground plane implementations.

Product Focus: AC-DC Converters
To their peril, embedded system developers often treat their choice of power supply as an afterthought. But choosing the right AC-DC converter is critical to the ensuring your system delivers power efficiently to all parts of your system. This Product Focus section updates readers on these trends and provides a product album of representative AC-DC converter products.

SENSORS TAKE MANY FORMS AND FUNCTIONS

Sensors and Measurement
While sensors have always played a key role in embedded systems, the exploding Internet of Things (IoT) phenomenon has pushed sensor technology to the forefront. Any IoT implementation depends on an array of sensors that relay input back to the cloud. Circuit Cellar Chief Editor Jeff Child dives into the latest technology trends and product developments in sensors and measurement.

Passive Infrared Sensors
One way to make sure that lights get turned off when you leave a room is to use Passive Infrared (PIR) sensors. Jeff Bachiochi examines the science and technology behind PIR sensors. He then details how to craft effective program code and control electronics to use PIR sensors is a useful way.

Gesture-Recognition in Boxing Glove
Learn how two Boston University graduate students built a gesture-detection wearable that acts as a building block for a larger fitness telemetry system. Using a Linux-based Gumstix Verdex, the wearable couples an inertial measurement unit with a pressure sensor embedded in a boxing glove to recognize the user’s hits and classify them according to predefined, user-recorded gestures.

SECURITY, RELIABILITY AND MORE

Internet of Things Security (Part 3)
In this next part of his article series on IoT security, Bob Japenga looks at the security features of a specific series of microprocessors: Microchip’s SAMA5D2. He examines these security features and discusses what protection they provide.

Aeronautical Communication Protocols
Unlike ground networks, where data throughout is the priority, avionics networks are all about reliability. As a result, the communications protocols used in for aircraft networking seem pretty obscure to the average engineer. In this article, George Novacek reviews some of the most common aircraft comms protocols including ARINC 429, ARINC 629 and MIL-STD-1553B

DEEP DIVES ON PROCESSOR DESIGN AND DIGITAL SIGNAL PROCESSING

Murphy’s Laws in the DSP World (Part 1)
A Pandora’s box of unexpected issues gets opened the moment you move from the real world of analog signals and enter the world of digital signal processing (DSP). In Part 1 of this new article series, Mike Smith defines six “Murphy’s Laws of DSP” and provides you with methods and techniques to navigate around them.

Processor Design Techniques and Optimizations
As electronics get smaller and more complex day by day, knowing the basic building blocks of processors is more important than ever. In this article, Nishant Mittal explores processor design from various perspectives—including architecture types, pipelining and ALU varieties.

The Dick Tracy Wristwatch TV

Input Voltage

–Jeff Child, Editor-in-Chief

JeffHeadShot

At my first technology editor job back in 1990, my boss at the time was obsessed with the concept of the Dick Tracy wristwatch. Dick Tracy was a popular comic strip that ran from the late 30s up until 1972. Now, let me be clear, even I’m not old enough to be from the era when Dick Tracy was part of popular culture. But my boss was. For those of you who don’t know, the 2-Way Wrist Radio was one of the comic strip’s most iconic items. It was worn by Tracy and members of the police force and in 1964 the 2-Way Wrist Radio was upgraded to a 2-Way Wrist TV. When chip companies came to visit our editorial offices—this is back when press tours were still a thing—in many editorial meetings with those companies, my boss would quite often ask the hypothetical question: “When are we going to get the Dick Tracy wristwatch?”

Confident that Moore’s Law would go on forever, semiconductor companies back then were always hungry to get their share of the mobile electronic device market—although the “device” of the day kept changing. My boss’s Dick Tracy wristwatch question was a clever way to spur discussion about chip integration, extreme low power, wireless communication and even full motion video. Full motion video on a mobile device in particular was a technology that many were skeptical could ever happen. In that early 90s period, the DRAM was the main driver of semiconductor process technology, and, in turn, the desktop PC was by far the dominant market for DRAMs. As a result, there was a tendency to view all future computing through the lens of the PC. It would be more than a decade later before flash memory surpassed DRAMs as the main driver of the chip business, and that was because the market size of mobile devices began to eclipse PCs.

As most of you know, Circuit Cellar has BYTE magazine as a part its origin story. Steve Ciarcia had a popular column called Circuit Cellar in BYTE magazine. When Steve founded this magazine three decades ago, he gave it the Circuit Cellar name. The April 1981 issue of BYTE magazine famously had a picture of basically a wristwatch with a CRT screen and keyboard with a mini-floppy disk being inserted into its side. That’s a vivid example that we humans are notoriously really bad at predicting what future technologies will look like. We have an inherent bias imposing what we have now on our view of the future.

Fast forward today and obviously we have the Dick Tracy Wristwatch and so much more—the Apple Watch being the most vivid example. Today’s wearable devices span across the consumer, fitness and medical markets and all need a mix of low-power, low-cost and high-speed processing. But even though technology has come a long way, the design challenges are still tricky. Wearable electronic devices of today all share some common aspects. They have an extremely low budget for power consumption, they tend not to be suited for replaceable batteries and therefore must be rechargeable. They also usually require some kind of wireless connectivity.

Today’s wearables including a variety of products including smartwatches, physical activity monitors, heart rate monitors, smart headphones and more. Microcontrollers for these devices have to have extremely low power and high integration. At the same time, power solutions servicing this market require mastery of low quiescent current design techniques and high integration. To meet those needs chip vendors—primarily from the microcontroller and analog markets—keep advancing solutions that consume extremely low levels and power and manage that power.

One amusing aspect of the Dick Tracy wristwatch was that it was referred as a 2-Way Radio (and later a 2-Way TV). With Internet connectivity, today’s smartwatches basically are connected to an infinite number of network nodes. I can’t claim to be a better predictor of the future than the editors of 1981’s BYTE. But now I need to come up with a new question to ask chip vendors, and I don’t know what the question should be. Perhaps: “When are we going to get the Star Wars holographic 3D image messaging system?”. And in wristwatch form please.

Displays Fit Diverse Embedded System Needs

Many Sizes and Solutions

The types of displays available for embedded applications are as diverse as embedded applications themselves. Whether your requirement is for small, smart, rugged or rain-proof, there’s probably a display solution that suits your system design needs.

By Jeff Child, Editor-in-Chief

Long gone are the days when the Graphics Processor Unit (GPU) market was filled with many semiconductor vendors jockeying for position. A combination of chip integration: graphics function moving inside microprocessors—and business consolidation: graphics chip vendors getting acquired, has narrowed the technology space down to mostly Intel, AMD and NVIDIA. And while these vendors tailor their products for high-volume markets, embedded applications must adapt those same GPUs to their needs.

With that in mind, makers of displays for embedded applications are constantly evolving their products to keep pace with the latest GPU technologies and both new and legacy display interface standards. Technologies range from small e-paper displays to rugged sunlight readable displays for the outdoors to complete Panel PC solutions that embed PC functionality as part of the display.

Mobile Dominates GPU Market

Although this article is focused on displays in embedded systems, it’s helpful to first understand the larger markets that are driving GPU technology. For its part, Jon Peddie Research (JPR), a market research and consulting firm focused on graphics and multimedia saw mobile devices as the dominate market when they did their annual review of GPU developments for 2017. In spite of the slow decline of the PC market overall, PC-based GPU sales (which include workstations) have been increasing, according to the review. In the mobile market, integrated GPUs have risen at the same rate as mobile devices and the SoCs in them. The same is true for the console market where integrated graphics are in every console and they too have increased in sales over the year.

Nearly 28% of the world’s population bought a GPU device in 2017, and that’s in addition to the systems already in use. And yet, probably less than half of them even know what the term GPU stands for, or what it does. To them the technology is invisible, and that means it’s working—they don’t have to know about it.

The market for, and use of, GPUs stretches from supercomputers and medical devices to gaming machines, mobile devices, automobiles and wearables. Just about everyone in the industrialized world has at least a half-dozen products with a GPU, and technophiles can easily count a dozen or more. The manufacturing of GPUs approaches science fiction with features that will move below 10 nm next year and have a glide-path to 3 nm—and some think even 1 nm.

Innovative Adaptations

Throughout 2017 JPR saw a few new, and some clever adaptations of GPUs that show the path for future developments and subsequent applications. 2017 was an amazing year for GPU development driven by games, eSports, AI, crypto currency mining and simulations. Autonomous vehicles started to become a reality, as did augmented reality. The over-hyped, consumer-based PC VR market explosion didn’t happen—and had little to no impact on GPU developments or sales. Most of the participants in VR already had a high-end system and the head-mounted display (HMD) was just another display to them.

Mobile GPUs, exemplified by products from Qualcomm, ARM and Imagination Technologies, are key to amazing devices with long battery life and screens at or approaching 4K. And in 2017 people started talking about and showing High dynamic range (HDR). JPR’s review says that many, if not all, the developments we will see in 2018 were started as early as 2015, and that three to four-year lead time will continue.

Lead times could get longer as semiconductor engineers learn how to deal with chips constructed with billions of transistors manufactured at feature sizes smaller than X-rays. Ironically, buying cycles are also accelerating ensuring strong competition as players try to leap-frog each other in innovation. According to JPR, we’ll see considerable innovation in 2018, with AI being the leading application that will permeate every sector of our lives. The JPR GPU Developments in 2017 Report is free to all subscribers of JPR. Individual copies of the report can be purchased for $100.
