The quest for higher speed of operations has been the trend for last two decades and there was not much research efforts to find the right device solutions for the low speed digitals devices with really low sleep power consumption.

Sounds like an interesting forking road ahead, and an interesting startup to watch.

It will be fascinating to see what sorts of designs such cores could enable.

@Rick

Short answer, yes.

I get the impression that Ambiq is Cortex-M0+ development while ARM is doing next-gen core research.

NEAR versus SUB

But note well ARM's processor core is being optimized for energy harvest type use in a NEAR-threshold implementation. This makes sense if ARM wants TSMC to provide support with a process flow and be able to license the core widely.

On the other hand Ambiq is aggressively going after SUB threshold because they are prepared to back their design skills and take on the risk of working outside TSMC's design flow envelope.

There is a UK company, Toumaz Ltd., that has used this technique but the company is focused at the system level in health-care products and consumer audio, having bought Frontier Silicon.

There is a penalty on switching speed.

So you get less done but more power efficiently than using conventional design and voltages.

Hence the focus on extreme power-critical applications rather than on general purpose MCU.

That is going to depend as much on the lawyers as the engineers. If they have good patent protection then they should be OK, but the fact that Arm Holdings funded them probably means that they are keeping an eye on the technology. I could see them getting bought out if Arm decides to integrate it as core technology.

Did they say if there is a penalty on switching speed or accuracy with this technology? It seems like there would be some kind of price to be paid for the increased power efficiency.

If they are ahead of the curve, it is exactly the sort of company Apple likes to acquire.  If they go dark at some point in the future, we'll know what happened :)

Do you think Ambiq can deliver something thats differentated before ARM rolls its own sub-threshold core for IoT?

NEXT UPCOMING BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
