HD video cameras have become so much smaller these days. They can be
mounted on a bike helmet or embedded in goggles or even worn on a vest
by war correspondents.
Chris Day, Ambarella's vice president of marketing
and business development, remembers one of the first customer meeting he
had when he joined the company a few years ago. The customer wanted
to know what percentage of these tiny sports cameras might become
wireless. Day guesstimated about 20 percent at that time. Day told me
last week, “Well, I actually had no idea. But I didn’t want to give them
a number that may sound too small to them…so I just said, 20 percent.”
It turns out literally 100 percent of those wearable sports cameras today come with wireless features.
importantly, the point of these tiny cameras going wireless is that
users can now use a smartphone as viewfinder and monitor. “You can’t see
what you are recording unless you have a display,” said Day. In other
words, consumers can now do wireless preview, playback and upload of
still and videos to a smartphone (or to the Internet)--all via WiFi.
the end, keeping Ambarella--which went public last October--healthy
today is a camera business that exploits the proliferation of
smartphones. How cool is that?
Ambarella announced at the CES a
new camera system-on-chip, called A9, featuring support for the new 4K
ultra HD video standard, advanced fast-action video features and full
In addition to 4K video resolution at 30
frames per second, the A9 supports high frame-rate video for capturing
fast-action sports with 1080p video at 120 frames per second or 720p
video at 240 frames per second. Higher frame rates enabled in the A9 SoC
would be perfect for capturing fast action and playing back in smooth
slow motion (i.e. Think Asian customers who want to review their golf

renowned engineering executives like Ambarella’s CTO, Les Kohn, who was a
fellow at Sun developing Sun’s UltraSPARC, and Ambarella’s executive
vice president Didier LeGall, co-founder and CTO of C-Cube, “We know how
to do rocket-science stuff when it comes to microcode, algorithms and
computational optimizations,” said Day. He added, “Our claim-to-fame is
that our chips are extremely low power.”

I work in security research and management. Let me tell you folks, this is design chip has numerous vulnerabilities. I think an experienced chipmaker can easily defragment the information if he has access to one. Thanks for this post! http://www.ordergripgo.com/buy-gripgo/use-gripgo-and-ensure-safety/
I thought it was going to be some boring old post, but it really compensated for my time. I will post a link to this page on my https://twitter-followers-buy.com/ blog. I am sure my visitors will find that very useful.
I think people judges the quality of operating system and software along with processors and other hardware configuration when buying a smart phone. App developers like https://gripd.com/ are really making smart phone to a replacement option for laptops and desktops.
Using a phone as a dumb monitor is one of the best innovations I've seen in a while. You only need the display long enough to verify operation so why burden the consumer with the added cost of it. People tend to upgrade their phones every 2~3 years, but the camera should easily outlive that and still be useful. Why didn't I think of that?
thank you Junko...yes, if they are truly successful and wireless sport cameras are purchased in large numbers a smartphone company can integrate this in...not an easy strategy to execute, you need to stay in the niche but you don't want your niche to become too large
Hi, Kris. Precisely for that reason, Ambarella walked away from the smartphone market. Instead, the company discovered a segment (tiny, wireless sports cameras -- sans displays of their own -- that you can wear on your vest or helmet, for example)that takes advantage of the smartphone.
But of course, if you are saying that those tiny wearable sports cames are going to become smartphones, yes, that could be a problem.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
