Yeah. Apple looks very different. Its M7 used NXP's Cortex-M3 based LPC18A1, of which the ARM core is optimized for performance efficiency. I guess the teams from both Apple and NXP have done a lot of things to improve the coprocessor's power efficiency.

@BruceWang It seems most of the exisiting solutions are ARM Cortex-M0/0+

That's because its been optimized for ultra-low power.

It is exciting that most MCU/MEMS vendors have been showing their muscles since Apple released its latest iPad product with M7 sensor hub coprocessor. It seems most of the exisiting solutions are ARM Cortex-M0/0+ based or comparable solutions, which target extemely energy efficiency but with limited computing capabilities.

Will Cortex-M3/4 based solutions be coming out in the future to meet ever-increasing more complex computing tasks, e.g., 3-D recognition, while still tailored for low energy requirement by other advanced low power design techniques?

It's amazing to me hpow fast the sensor hub has emewrged from nowhere.

BTW I love KitKat

@selinz "What, then, is Android trying to catch up on?"

Apple already has these sensor fusion functions and context awareness capabilities built in to its M7 sensor hub on the iPhone-5s.

I'm a bit confused. You keep talking about features that are available in Android but not Apple but Android is playing catch up? What, then, is Android trying to catch up on? Or did I miss something?

The old 9 axis part is 4mmx4mm, this new one is 3mmx3mm and is mechanically compatible with the 6 axis parts. It is unknown yet if they will include the software upgrades to support Kit Kat functions.

KevinCBaxter If you need contextual awareness in a smart device then a 9 axis part in Q1 will have a far better solution.

No argument there. Of course some cost-sensitive applications don't require nine-axis.

They already have the MPU9150, what is the difference between this one and the device you are referring to?

This seems like a very incremental announcement of a so-so drop-in improvement part, in Q4 Invensense is due to have a 9 axis drop-in part which I would far prefer. MEMs inertial parts drift badly and without the magnetometer which the new 6 axis MPU-6515 doesn't have, it is going to get lost rather quickly. If you need contextual awareness in a smart device then a 9 axis part in Q1 will have a far better solution.

LATEST ARCHIVED 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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
