Ten years and rolling

Ten years ago today the Mars Rover Opportunity bounced its way on to the surface of Mars, at the start of a three month mission. In that time, as well as driving 24 miles, the little machine has added enormously to our understanding of the history of the planet.

And this is a huge endorsement of the team who put together the electronics. The development process started nearly twenty years ago, and by the time the mission launched most of the electronics used was, to put it kindly, mature. The central processor is a 32 bit Rad 6000 microprocessor, a radiation-hardened version of a Power PC that was launched in around 1965.

Just look around- how much of the electronics you own is ten years old and still functioning? What software are you using that ceased development around 15 years ago.  That is a little unfair since the software on Opportunity has undergone several upgrades.

That in itself is quite mind-boggling. When did you last do a major software upgrade and how easily did it go?

This week there was another space event that was a tribute to system designers. The Rosetta mission to investigate comet Churyumov-Gerasimenko woke up after 31 months in hibernation mode the latest stage in journey that started almost ten years ago.

So It is possible to create systems that last for years- you just have to work hard at it.

Demo: Inuitive NU4000 SoC with ARC EV Processor Running SLAM and CNN

Sponsored by Synopsys

Autonomous vehicles, robotics, augmented and virtual reality all require simultaneous localization and mapping (SLAM) to build a map of the surroundings. Combining SLAM with a neural network engine adds intelligence, allowing the system to identify objects and make decisions. In this demo, Synopsys ARC EV processor’s vision engine (VPU) accelerates KudanSLAM algorithms by up to 40% while running object detection on its CNN engine.

New package technology improves EMI and thermal performance with smaller solution size

Sponsored by Texas Instruments

Power supply designers have a new tool in their effort to achieve balance between efficiency, size, and thermal performance with DC/DC power modules. The Enhanced HotRod™ QFN package technology from Texas Instruments enables engineers to address design challenges with an easy-to-use footprint that resembles a standard QFN. This new package type combines the advantages of flip-chip-on-lead with the improved thermal performance presented by a large thermal die attach pad (DAP).

Addressing Digital Implementation Challenges with Innovative Machine Learning Techniques

Sponsored by Cadence Design Systems

Machine learning is revolutionizing our designs these days with impressive new capabilities. But, have you considered using machine learning to actually create better designs? In this episode of Chalk Talk, Amelia Dalton chats with Rod Metcalf of Cadence Design Systems about how Cadence is using machine learning to help us get more out of our design tools - optimizing a wide range of design automation processes go give us better results in less time.
