EtaCore ARM Cortex M3 Core Operates at Low Voltage (0.25V and up) for Higher Power Efficiency

We’ve previously seen Ambiq Micro offering Apollo ARM Cortex M4F MCU with Cortex M0+ energy efficiency, and later the upgraded Apollo 2 MCU with even lower power consumption and better performance. The company can achieve such efficiency thanks to low sub-thresold operating voltage in the 0 to 0.5V range. Another startup – Eta Compute – is now offering another low voltage solution with their EtaCore ARM Cortex M3 IP, and other IP blocks operating at low voltage (0.25 to 1.2V). Eta Compute claims a “10x improvement in power efficiency over any alternative”, and battery life of over 10 years on a CR2032 coin cell. Their website does not provide that many details about the core and development tools, but still mentions the following: The only commercially available self-timed technology supporting dynamic voltage scaling (DVS) that is insensitive to process variations, inaccurate device models, and path delay variations Includes M0+ and […]

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted.  That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon. The company has recently announced their Track 100 family […]

Ambiq Micro Introduces Ultra-Low Power Apollo 2 Cortex-M4F MCU Consuming Less than 10 μA/MHz

Last year Ambiq Micro unveiled their Apollo Cortex-M4F MCU with Cortex M0+ energy efficiency thanks to operation in sub-threshold voltage (< 0.5 V), and the MCU is said found in Matrix Powerwatch, a fitness tracker powered by body heat that you never need to charge. The company has recently announced a new version of the micro-controller with Apollo 2 MCU with better maximum performance thanks to a higher maximum clock speed (48 MHz vs 24 MHz), and higher efficiency (10 μA/MHz vs 30 μA/MHz @ 3.3V). Apollo 2 MCU key features and specifications: Ultra-low supply current <10 μA/MHz executing from flash at 3.3 V <10 μA/MHz executing from RAM at 3.3 V ARM Cortex-M4 Processor up to 48 MHz with FPU, MMU, wake-up interrupt controller with 32 interrupts Ultra-low power memory Up to 1 MB of flash memory for code/data Up to 256 KB of low leakage RAM for code/data […]

Embedded Linux Conference and OpenIoT Summit Europe 2016 Videos are Now Available Online

The Embedded Linux Conference and OpenIoT Summit Europe 2016 conferences took place on October 11 – 13 in Berlin, Germany, with many interesting talks about Linux, development boards, power management, embedded systems, software optimization, tools, and so on, as well as a few keynotes. The Linux Foundation has recorded most talks and keynotes, and made the videos available on their website. A free registration is required, and will redirect you to the full unlisted playlist on YouTube. Tim Bird keynote can be watch directly without registration. You can also download the slides for each presentation. Thanks to Harley for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com

NanoPi NEO Board Gets Armbian Debian 8 & Ubuntu 16.04 with Linux 4.6 & 4.7 (Mainline), h3consumption Power Consumption Tool

We’ve been blessed with a wide range of low cost Allwinner H3 boards thanks to Shenzhen Xunlong Orange Pi and FriendylARM NanoPi boards. Recently, armbian developers have been focusing on NanoPi NEO board, and they’ve now released Debian Jessie and Ubuntu Xenial with Linux 4.6.7 and Linux 4.7.2. The latter is mainline kernel with some patchsets for Ethernet. You can download the Linux 4.6.7 based “beta” images from armbian NanoPi NEO page, and selected the “Vanilla” versions, then flash then one a micro SD card as you would normally do. Linux 4.7.2 based “experimental” images with USB OTG support and schedutil cpufreq governor can be found on the separate server in a temporary directory. Thomas Kaiser explains further: Ethernet and throttling are working (the latter not as efficient as with legacy kernel but at least it protects the SoC from overheating). Please note that all vanilla kernel images currently suffer from […]
