Ambiq Micro Joins EEMBC to Collaborate in Development of Ultra-Low Power Microcontroller and IoT Benchmarks

EL DORADO HILLS, CA--(Marketwired - Nov 10, 2015) - The Embedded Microprocessor Benchmark Consortium (EEMBC) today announced that Ambiq Micro, a start-up company with a patented Subthreshold Power Optimized Technology (SPOT™) platform that dramatically reduces the amount of power consumed by semiconductors, has joined the consortium's working groups developing benchmarks for ultra-low power microcontrollers (MCUs) and Internet of Things (IoT) edge node systems.

The EEMBC ULPBench working group is developing a benchmark suite with various usage profiles that target different aspects of an ultra-low power microcontroller's functionality. The ULPBench-Core Profile, officially released in 2014, measures CPU core efficiency, as well as the microcontroller's real-time clock and calendar function (RTCC), and power modes. Published scores can be seen on the EEMBC website. Subsequent versions will focus on real-world applications utilizing integrated hardware and peripheral functions.

The EEMBC IoT working group is focused on delivering an industry-standard benchmark that ensures optimum efficiency of IoT edge nodes (end points). When designing an edge node device, battery-life is often one of the most important factors because of the need for portability and flexibility in placement. Therefore, this EEMBC benchmark will provide a method to reliably determine the combined energy consumption of the platform, taking into consideration the real-world effects of the microcontroller and radio-frequency component (e.g. Bluetooth and ZigBee).

"Earlier this year, Ambiq Micro used EEMBC CoreMark to demonstrate the advantages of its ultra-low power technology, showing an active mode current of 35uA/MHz," said Markus Levy, EEMBC President. This value represents excellent energy efficiency, but the ULPBench and IoT benchmarks will provide more suitable metrics for the types of battery-powered applications that Ambiq Micro is targeting. We're excited to have Ambiq Micro as a member of our working groups, offering their expertise in defining, developing, and testing our energy efficiency benchmarks."

"When we announced our Apollo MCU earlier this year it was important to us and our customers to have our extremely low-power results independently and rigorously validated," said Mike Noonen, interim CEO at Ambiq Micro. "Therefore, Ambiq Micro is delighted to join EEMBC and we are thrilled that our extraordinary energy performance will be benchmarked against our competitors and officially confirmed."

EEMBC, the Embedded Microprocessor Benchmark Consortium, was formed in 1997 as a non-profit organization that develops industry-standard benchmarks to test processors, microcontrollers, and the corresponding embedded systems. EEMBC benchmarks help ensure predictable performance of embedded processors and systems in a range of applications and disciplines. Its benchmarks are currently in use within thousands of companies and universities worldwide.
