Where Should Auto Sensor Data Be Processed?


Fully autonomous vehicles are coming, but not as quickly as the initial hype would suggest because there is a long list of technological issues that still need to be resolved. One of the basic problems that still needs to be solved is how to process the tremendous amount of data coming from the variety of sensors in the vehicle, including cameras, radar, LiDAR and sonar. That data is the dig... » read more

Inferencing At The Edge


David Fritz, head of corporate strategic alliances at Mentor, a Siemens Business, shows how to apply YOLO (you only look once) at the edge, allowing automotive companies to move from a GPU to a much more efficient processor. That allows inferencing to move much closer to the sensor, so neural networks can be tailored to the type of data being produced. From there the data can be abstracted and ... » read more

Is ADAS The Edge?


Debate is brewing over whether ADAS applications fall on the edge, or if they are better viewed squarely within the context of the automotive camp. There is more to this discussion than just semantics. The edge represents a huge greenfield opportunity for electronics of all sorts, and companies from the mobile market and from the cloud are both rushing to stake their claim. At this point the... » read more

System Bits: May 6


Transmitting data with a semiconductor laser Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences demonstrated a laser that can emit microwaves wirelessly, modulate them, and receive external radio frequency signals. “The research opens the door to new types of hybrid electronic-photonic devices and is the first step toward ultra-high-speed Wi-Fi,” said ... » read more

Uhnder: Digital Radar Chips


Radar used to be slow, clunky, and expensive. That's changing quickly as tech companies begin bringing single-chip or single-package solutions to market, setting the stage for a price/performance battle in markets ranging from automotive to robotics. Uhnder, an Austin, Texas-based startup, is the first to roll out a single-chip radar solution that it claims is roughly 100X less expensive tha... » read more

Racing To The Edge


The race is on to win a piece of the edge, despite the fact that there is no consistent definition of where the edge begins and ends or how the various pieces will be integrated or ultimately tested. The edge concept originated with the Internet of Things, where the initial idea was that tens of billions of dumb sensors would communicate through gateways to the cloud. That idea persisted unt... » read more

System Bits: March 26


Swear to tell the truth Lots of lies are told on the Internet. Shuyuan Ho of Florida State University wants to unveil those falsehoods with an online polygraph. “The future of my research is an online polygraph that could be used many different ways,” said Ho, an associate professor in the College of Communication and Information. “You could use it for online dating, Facebook, Twitter... » read more

Shedding Pounds In Automotive Electronics


Weight is emerging as a key concern for carmakers as more electronic circuitry is added into vehicles that are either fully or partially powered by batteries. As a result, chipmakers and OEMs are exploring alternative substrate materials, different types of sensor fusion, and new ways to reduce the number of wires. Adding pounds reduces driving range for electric or hybrid vehicles. The auto... » read more

Digital Signal Processing for Frequency-Modulated Continuous Wave RADARs


RADAR, LiDAR and vision systems play a critical role in enabling advanced driver-assistance systems (ADAS) and autonomous driving (AD). The automotive ADAS markets are forecast to grow at high rates in the upcoming years, with increasing requirements and system implementation complexity. This paper provides an overview of RADAR technology as used in ADAS applications, including a summary of the... » read more

Antenna Array Design for ADAS


By Milton Lien and David Vye By implementing radar technology over the 76 to 81 GHz spectrum, advanced driver-assist systems (ADAS) enable smart vehicles with the ability to alert and assist drivers in a variety of functions, from low tire-pressure warning to collision avoidance to self-parking. These automotive radar applications use the millimeter-wave (mmWave) spectrum to exploit more ban... » read more
