C V2X Talking Cars Toil and Trouble

Last year, the U.S. Federal Communications Commission sought to resolve the lingering dispute over the use of 75MHs of Wi-Fi spectrum in the 5.9MHz range, previously allocated to the automotive industry for safety applications, by designating 45MHz of that spectrum for unlicensed use while preserving 30MHz for automotive … Read More

Global Light Vehicle Production 2022

Several signs point to an easing of the shortages of semiconductors for automotive applications. However, the production of light vehicles will likely remain below full potential through at least 2023. LMC Automotive’s July forecast of light vehicle production called for 81.7 million units in 2022, up 2% from 2021. LMC’s January… Read More

Time for NHTSA to Get Serious

In the final season of “The Sopranos,” Christopher Multisanti (played by Michael Imperioli) and Anthony Soprano (James Gandolfini) lose control of their black Cadillac Escalade and go tumbling off a two-lane rural highway and down a hill. Christopher dies (spoiler alert) with an assist from Tony, before Tony calls “911” for… Read More

What is Your Ground Truth

When my son bought a 2020 Chevrolet Bolt EV a couple of years ago, I was excited. I wanted to see what the Xevo-supplied Marketplace (contextually driven ads and offers) looked like and I was also curious as to what clever navigation integration GM was offering.

I was swiftly disappointed to discover that Xevo Marketplace was not… Read More

Whats Wrong with Robotaxis

For some reason the obsession with robotaxis persists throughout the world and throughout the transportation industry. The collective conventional wisdom appears to be that getting rid of the human drivers of taxis and letting these vehicles freely operate presumably around the clock will save money and the environment.… Read More

Wireless Carrier Moment of Truth

When Cruise Automation’s cars recently began coming to a stop jamming up San Francisco streets senior wireless and automotive executives worldwide began shifting uneasily in their suites. In spite of demanding that General Motors build them an expensive telematics control unit (TCU) with four-carrier (at the time) connectivity,… Read More

DSPs in Radar Imaging. The Other Compute Platform
by Bernard Murphy on 07-20-2022 at 6:00 am

Radar Trends

In the flood of CPU and GPU announcements in pursuit of new technology advances, it is easy to lose track of another kind of platform – DSPs. Digital signal processors, once a niche platform for specialized applications, are now front and center in some of the hottest technologies. Because their strength in signal processing has… Read More

I recently had an update from Lu Dai, Chairman of Accellera, also Sr. Director of Engineering at Qualcomm. He’s always a pleasure to talk to, in this instance giving me a capsule summary of status in 3 areas that interested me: CDC, Functional Safety and AMS. I will start with CDC, a new proposed working group in Accellera. To manage… Read More


Scaling Safety Analysis. Reusability for FMEDA

Scaling Safety Analysis. Reusability for FMEDA
by Bernard Murphy on 06-23-2022 at 6:00 am

FMEDA generation

It is common when a new type of analysis is introduced in almost any domain that it works well enough for a while. Until it begins to struggle with growing problem size, prompting refinements to the methodology to allow continued scaling. We see this routinely in analytics for SoC design, so it should not be a big surprise that safety… Read More
