Image Processing Embedded Systems with Modular Hardware
Image processing embedded systems can be deployed quickly thanks to modular design tools With advances in industrial automation, automotive technology, remote sensing, and much more, image processing is taking center stage in many embedded systems. Image processing with older video systems was difficult or impossible due to the low quality of many imaging systems with perpetual uptime. As a result, older camera systems could be developed for

Using Low-Volume Runs to Eliminate High-Volume Failures
“High volume” is a relative term. It depends upon what your business does and how many of a product you plan to sell. For one OEM, a minimum initial run might be 250K units. For another, 10K is the expected run of a product across its entire market life. One way to consider “high volume” is that it’s large enough to hurt your business if you make a mistake. Put another way, high volume is high risk. And given the stakes, you want to minimize this

The Evolution Of Automotive Electronics Design
The number, functionality, and complexity of today’s automotive electronics has grown beyond leaps and bounds over the past several years. Certainly, the flagship of this technology is the Tesla automobile. But, even for those of us who can’t afford a Tesla, there is an increasingly widespread utilization of this technology in mid-range and even lower-end new cars. This article will describe the design environment represented by this technology

DDR5 PCB Layout and Signal Integrity Guidelines: What Designers Need to Know
Release of the DDR5 standard was announced in July 2020, about 18 months after the announced development of the first RAM module following the proposed standard. The standard allows peak speeds in excess of 5200 MT/sec/pin (compare that to 3200 MT/sec/pin with DDR4), with JEDEC-rated speeds up to 6400 MT/sec/pin and channel bandwidth increased up to 300 GB/s. Demand for this new generation of memories with 8, 16, and 32 GB capacities should

Linux and Android: What’s the Difference
When purchasing an off-the-shelf module or designing a customized module of your own using a design tool like Upverter (previously known as Geppetto), you have to select an operating system. Often, you have a variety of choices. Two popular open source software (OSS) platforms are Linux and Android. If you’re new to design, how do you know which one you want to use? There are complicated, highly technical answers to this question. However, if you

Open Source Software - A Moving Target
Open Source Software (OSS) is an attractive alternative to proprietary software platforms. There’s a lot to love about OSS. Lower cost is a primary decision driver for many companies. Others want to enjoy the freedom and flexibility to modify the software to their particular application requirements. Some companies don’t want to be at the mercy of the direction—or lack of direction—of proprietary software roadmaps. There’s also a lot to fret over

Crowdsourced Voice Recordings: A Wearable AI Voice Recorder Is Shipping
Use a Senstone and never miss a flash of creative genius again (Image source: Senstone.com) Were you ever a fan of Star Trek: The Next Generation (TNG)? If so, you may recall that the Starfleet officers and enlisted personnel wear small communicator badges on their left breast. These devices are presented in the shape of the Starfleet insignia and are activated with a light tap. They also incorporate a universal translator, which comes in handy

Power Consumption Optimization
Power efficiency—energy efficiency if you’re a purist—has become perhaps the highest-profile aspect of system design. This is especially true for IoT applications where a device may need to operate for years on harvested energy or a cell battery. Thus, a critical stage of design is power optimization. Typically, the first stage of power optimization is setting the power budget . For example, the system spec might state that the device has to be

Continuous Manufacturing
Volume As a manufacturing term, it can mean different things, depending upon the industry. Volume production for an automotive OEM means hundreds of thousands of units. For an industrial CNC manufacturer, lifetime sales over decades might be in the tens of thousands. For many small design companies, producing even “low” volumes may be a manufacturing challenge. It takes success to be able to invest in infrastructure that supports higher volumes

MIPI Physical Layer Routing and Signal Integrity
MIPI physical layer routing (C-PHY) is typically used to connect these smartphone cameras to a processor. When most designers talk about routing standards, particularly for advanced devices, they typically refer to differential routing standards (e.g., LVDS) that enable high data rates. These signaling standards have proliferated computers, networking equipment, smart electronics, and other areas, and they have been critical for operating with

Webinar on XR | Think AR on Steroids
Making the business case for XR (Image source: XR Intelligence) Do you remember when the internet first reached the popular consciousness with the release of the MOSAIC web browser circa 1993? A couple of years later, even though almost everyone was aware of the internet by that time, many companies -- including large, multibillion-dollar concerns -- were still debating internally whether it was worth spending their time and resources on having

8-Bit Micros are Alive and Kicking in Nucleo-8s207k8 Boards
The NUCLEO-8S207K8 board boasts a 32-pin STM8S207K8 MCU (Image source: STMicroelectronics) I just heard from the guys and gals at STMicroelectronics (ST) that they are "making design starts using 8-bit STM8 microcontrollers (MCUs) faster, more affordable, and more accessible for creative minds of all types by introducing new development boards in the easy-to-use Nucleo-32 form factor." We will return to consider these little rascals in a moment

A Retro-Computing Christmas
Sinclair 48K ZX Spectrum computer (1982) (Image source: Bill Bertram/Wikipedia) It's starting to look a lot like (a retro-computing) Christmas. I understand why many younger readers cannot imagine a world before today's incredibly powerful computing and gaming systems with their high-resolution graphics subsystems. We all enjoy these systems, but those of us who are more... let's say "seasoned"… remember the raw excitement we felt just to own any

Geeky Holiday Gift Ideas
The holiday season is coming! I asked both the Altium community and my Altium Library community what geek gifts they are looking for, and I’ve added some of my own for the first ever Altium Geek Gift Guide! This is mostly for electronics geeks, but there should be something for everyone! There are so many amazing geek gifts out there it would be impossible to cover them all, so I’ve tried to keep to community suggestions. I then added just a few

WifiWall Technology Protects Against Cyberattacks
Do you travel a lot? If so, do you use your smartphone, tablet, or notepad computer in airports or hotels? Even if you aren't a road warrior, do you use any of the aforementioned devices in public places like coffee bars? WiFiWall 5.0 Traveler (Image source: WiFiWall.com) In my case, I would answer with a resounding "Yes" to all the above. Of course, just about everyone these days knows that public Wi-Fi is subject to nefarious folks mounting all

Python and CodeBots Dragging Students into STEAM
CodeBot. Image source: Firia Labs I have a friend. It's true. I'm not joking. Settle down. Look -- I'm not going to continue until you cease squirming in your seat and stop giggling. That's better. Now, if you're quite finished, we'll continue. We'll call my friend David (because that's his name). David is one of the cleverest guys I know. He has a size-16 brain -- the type with the go-faster stripes painted down the side. He has expertise with

Electronics System-Level Circuit Engineering Design in Altium Designer
Electronics system level design lets you focus on functionality and abstraction The day-to-day life of a PCB layout engineer is all about translating schematics into a real, manufacturable PCB. Before this can happen, designs begin at an abstract level that focuses on designing functionality. As the overall design process progresses, design requirements are made more granular, reaching the signal processing level and, eventually, the component
