Isn’t Sensor Fusion CPU-Agnostic?

Sensor fusion is algorithms. And these algorithms are typically executed as software. So that should be simple, right?

Just get your sensor fusion libraries from whomever you prefer (could be the sensor vendor, could be one of the sensor-agnostic folks), and then run it in the processor of your choice.

That processor could be the AP in a phone, although more and more that’s deprecated in favor of sensor hubs and other local, less power-hungry resources. Largely microcontrollers. And there shouldn’t really be any dependence on the specific computing platform chosen – as long as it has the resources to handle the algorithms. Right?

So I was a bit surprised when I saw that Movea and ST had collaborated to make Movea’s sensor fusion available on a very specific ST microcontroller: the STM32F401. Wouldn’t Movea’s stuff work on any ST microcontroller? Or anyone else’s, for that matter?

The answer is yes. Turns out that the collaboration alluded to in the announcement reflected work that Movea did to optimize their algorithms for that particular microcontroller. So the implication would be that, although you could run the algorithms on other ST microcontrollers, for example, they would run most efficiently on this particular one. Says ST’s Michael Markowitz, “This is precisely the result of a custom optimization by Movea to perfectly map the F401, which has an architecture that is well suited to performing sensor fusion at very low power.”

And, as such, ST would appear to be positioning that particular microcontroller as its preferred sensor hub platform. But there’s nothing that says you can’t use a different one.

You can find out more about this particular combination in the ST/Movea release.

Use Configurable Digital IO To Give Your Industrial Controller the Edge

Sponsored by Maxim Integrated

As factories get bigger, centralized industrial process control has become difficult to manage. While there have been attempts to simplify the task, it remains unwieldy. In this design solution, Maxim briefly reviews the centralized approach before looking at what potential changes edge computing will bring to the factory floor. They also show a digital IO IC that allows for smaller, more adaptable programmable logic controllers (PLCs) more suited to this developing architecture.

Thunderbolt Technology Overview

Sponsored by Mouser Electronics and Intel

Thunderbolt is the closest thing we’ve got to universal interconnect between a wide variety of devices and systems. With a universal USB-C connector, it can do video, power, data communication - all at scalable rates with smart adjustment. In this episode of Chalk Talk, Amelia Dalton chats with Sandeep Vedanthi of Intel about the latest in Thunderbolt technology - Thunderbolt 4, which brings a number of benefits over previous versions.
