Life on the “Edge”
Satyen Yadav, General Manager, IoT Ecosystem Development, Amazon Web Services
Today, an increasing number of objects are being connected to the internet at an unprecedented rate. As a result, customers are collecting vast amounts of valuable IoT data that was previously unavailable. We are already seeing the benefits of applying machine learning models to process data at the source where it is being generated- farmers predict crop yield, power companies predict energy demand, vehicles can identify distracted drivers, and doctors deliver improved care with real-time insight from medical devices … the possibilities for applying intelligence at the edge are countless. However, processing and analyzing this vast amount of IoT data is not possible with the help of traditional business intelligence tools. In this session, we will showcase how customers can use AWS’s IoT, artificial intelligence, and machine learning services to gain predictive insights and take intelligent, real-time actions on their IoT data, from the cloud to the edge.

He was an Associate Professor at the Delft University of Technology before joining Philips Research in 1996. In 2006 he joined NXP Semiconductors when it was spun out of Philips Electronics. In 2009 he joined Virage Logic, which was subsequently acquired by 草榴社区. He has worked on a broad range of topics including multi-processor architectures and system design methodologies.The ARC EM DSP processors are extremely well-suited for performing machine learning inference in always-on IoT devices. Smart IoT devices increasingly offer always-on features to allow advanced user control. For example, they can be always-listening to allow control through voice commands, or always-watching to support system wake-up by means of a face trigger. Such always-on functions often employ machine learning techniques for recognizing voice commands, faces, etc. A key requirement for implementing such functions is a very low power consumption, as battery lifetime is key for the always-on capability. In this presentation we discuss the key features of the ARC EM DSP processors that enable efficient machine learning inference. We then show how excellent results, in terms of low MHz requirements, small code size and low power consumption, are achieved for voice trigger and face trigger applications.

Using Trace Visualization for Efficient Debugging of Embedded Systems
Johan Kraft, CEO, Percepio
Software issues related to timing or resource usage can be difficult since they are not directly visible in the source code, but rather are an emerging property of the system. Such issues call for software tracing. Developers often associate tracing with instruction tracing and overwhelming amounts of low-level information, where you can’t see the forest for all the trees. However, recent advances in trace visualization and software-generated tracing offers an alternative approach that is more suitable for finding anomalies in complex software behavior. This presentation introduces software tracing and demonstrates the potential of state-of-the-art trace visualization, using Percepio Tracealyzer as an example.
