|This Week’s Cool Product|
|I’ve been following Eta Compute for a while. Like some other vendors, their interest is putting a little machine learning capability at the “edge” – in a microcontroller right at the sensors. What makes them a bit different is their focus on doing this at extremely low power levels.Eta’s new ECM3532 is an MCU with a Cortex M3 and DSP with dual MACs. The latter, of course, is optimized for multiply-accumulate operations, which are at the heart of inferencing. The company claims (I’ve seen their eval boards running off 1 cm2 solar cells) power consumption of under 5 µA/MHz, which is around an order of magnitude better than most ultra-low-power MCUs. Instead of dynamic voltage and frequency scaling, they tout continuous voltage and frequency scaling, with a near-threshold low-end Vdd of 0.54 V.Near- and sub-threshold operation yields very low power operation at low frequencies. Ambiq is one of the pioneers in this area. FETs can operate in three regions: subthreshold, linear, and saturated. But in the subthreshold region leakage is a problem, and temperature even more so. Transistors are not well characterized at those voltage levels, so vendors resort to clever, often secret, tricks. I’m told digital watches, at least the non-smart versions, operate in the subthreshold region giving them tremendous battery lives. For more on subthreshold voltage operation of FETs see this.One of those tricks Eta uses is a non-synchronous architecture. Though there is a clock, the logic isn’t conventionally clocked. It’s self-timed. Synchronous circuits need plenty of margin to insure all of the timing is properly closed; self-timed versions report back as soon as an operation has completed so the next can begin. Absent this, since FETs operating in or near the subthreshold region can have wildly-varying characteristics depending on temperature, huge|
Eta Compute Named as a Cool Vendor in Gartner’s May 2020 Cool Vendors in IoT Thingification Report
WESTLAKE VILLAGE, Calif., May 27, 2020 – Eta Compute Inc., a company dedicated to delivering machine learning to IoT and edge devices using its revolutionary Neural Sensor Platform, announced that it was recognized in Gartner’s May 2020 Cool Vendors in IoT Thingification* report.
“We are delighted to be named a Cool Vendor by Gartner,” said Ted Tewksbury, CEO of Eta Compute. “Our innovative multicore processor and self-timed CVFS technology are changing the way designers approach machine intelligence for energy-constrained products. In our opinion this Gartner recognition validates our vision of enabling intelligence everywhere in the smallest embedded devices and making IoT a reality.”
Eta Compute’s unique approach has been to attack constraints directly by reinventing the way intelligent devices are architected and designed. The company leverages its transformative low power technology and hybrid multicore design to address performance, power and cost constraints. With its patented Continuous Voltage Frequency Scaling (CVFS) technology and production of its ECM3532, the world’s first true AI multicore processor, the company has solved the hardware issues hindering the wide deployment of AI at the extreme edge.
