IoT Technical Report #1
By Romain Picard on Monday 6 March 2017, 10:00 - Permalink
Welcome to the IoT Technical Report. I will publish each month a short selection of technology news that happened in the IoT world. You will find here the most relevant discoveries and publications in the following domains : Machine learning, distributed systems, energy, embedded systems, and hardware.
MIT develops a speech recognition chip that uses a fraction of the power of existing technologies
MIT announced today that it’s developed a speech recognition chip capable of real world power savings of between 90 and 99 percent over existing technologies. Voice technology has, of course, become nearly ubiquitous in mobile devices, thanks to the exponential growth of smart assistants like Siri, Alexa and Google Home – but the new chip could help branch out in much simpler electronics.
Long-lasting flow battery could run for more than a decade with minimum upkeep
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.
On-Device Machine Intelligence
To build the cutting-edge technologies that enable conversational understanding and image recognition, we often apply combinations of machine learning technologies such as deep neural networks and graph-based machine learning. However, the machine learning systems that power most of these applications run in the cloud and are computationally intensive and have significant memory requirements. What if you want machine intelligence to run on your personal phone or smartwatch, or on IoT devices, regardless of whether they are connected to the cloud?
Espressif ESP8266 WiFi-serial interface : weekend die-shot
Die size 2050x2169 µm, half of which is occupied by transceiver and PA, 25% - on-chip memory (rough size estimations are ~300KiB), and the rest is Xtensa LX106 CPU core and other digital logic. Chinese engineers did an outstanding job here on finally making WiFi IoT devices cost effective.
Espressif ESP32 - integrated Wi-Fi transceiver: weekend die-shot
Espressif ESP32 sets the new level for widely available WiFi/Bluetooth transceivers. Now with 2x LX108 CPU core and 520kB RAM. Surprisingly - includes integrated hall sensor. Manufactured on TSMC 40nm ULP technology. Huge upgrade over their previous highly successful ESP8266. Hopefully next time we'll see their take on 5.8GHz ISM band. Die size 2960x2850 µm (~double the area of ESP8266).
Tech giants want to use blockchain to secure IoT apps
Cisco Systems and Foxconn are among a handful of companies who have set up a consortium to work on how blockchain can be used to secure and improve internet of things applications.
The 2017 edition of Fosdem happened the first week end of this month. Among all the talks of very different subjects, Two on distributed systems were very interesting: The distributed systems behind Ring, and It's time to SAFE the Internet.
