Smart Hearing is Heating Up

Smart Hearing is Heating Up

A lot of the attention in intelligent systems is on object detection in still or video images but there’s another very active area, in smart audio. Amazon and Google smart speakers may be the best-known applications but there are more obvious (and perhaps less novelty-driven) applications in enhancing the hearing devices we already… Read More

If you practice in advanced levels of power management, you know about dynamic voltage and frequency scaling (DVFS). This is where you allow some part of a circuit, say a CPU, to run at different voltages and frequencies depending on acceptable performance versus thermal tradeoffs and battery life on a mobile device. Need to run… Read More

ARM announced today a comprehensive suite of solutions for IoT support, from IP optimized for applications in this space all the way to cloud-based support to manage edge devices in the field. Their motivation is to provide a faster path to secure IoT, from the chip to the cloud. One especially interesting component of this solution… Read More


Unlock the Key to Ultra-Low Power Design

Unlock the Key to Ultra-Low Power Design
by Tom Simon on 06-20-2015 at 7:00 am

We have been hearing about low power for a long time. Fortunately, low power chip operation has come about through a large number of innovations. Key among these is clock gating, frequency and voltage scaling, managing leakage with lower threshold voltage, HKMG, and many other techniques. But we are entering the age of ultra low… Read More

When the RISC movement surfaced in 1982, researchers analyzed UNIX to discover what instructions multi-user code was actually using, and then designed an instruction set and execution pipeline to do that better. Fewer instructions meant fewer transistors, which led to less power consumption – although in the original… Read More

To understand how challenging it is to successfully implement Always-on Technology, consider doing any kind of sport while holding your breath. Sounds crazy? There’s actually one sport in which participants do just that – freediving. So what does freediving have to do with always-on technology? Quite a few things apparently.Read More


Always-on and the new wearable core

Always-on and the new wearable core
by Don Dingee on 06-01-2014 at 11:00 am

Recently, I mentioned smartphone SoCs consume one, maybe two orders of magnitude too much power for broader use in wearables. However, that is only when they are “on”. To save power and stretch battery life, smartphones spend a lot of time napping – display off, sitting still with MEMS sensors powered down, waiting for an incoming… Read More


What’s not quite MCU, and not quite SoC?

What’s not quite MCU, and not quite SoC?
by Don Dingee on 05-21-2014 at 10:10 am

There has been a lot of railing lately about how we don’t have quite the right chips for the upcoming wave of wearables. Chips one would drop in a smartphone are often overkill and overpowered, burning through electrons too quickly. Chips one would use for a simple control task generally lack peripherals and performance, offsetting… Read More

With a well-chronicled share inside cellular baseband interfaces for mobile devices, one might think that is the entire CEVA story, especially going into Mobile World Congress 2014 this week. MWC is still a phone show, but is becoming more and more about the Internet of Things and wearables, and CEVA and its ecosystem are showing… Read More
