Benchmarking the Impact of IoT Security

What are the performance requirements for IoT security implementations? What kind of latency effects does your IoT system encounter when implementing security? How much energy does it require? These and more are the types of questions being addressed in EEMBC’s new IoT security benchmark working group. No more public details are available at this time, but if you are interested in participating in this working group, contact EEMBC.

Mobile Imaging and Autonomous Driving Performance Metrics

What about a benchmark that can test CPU+GPU or other performance-accelerator technologies targeted at mobile imaging and automotive? No more public details are available at this time, but if you are interested in participating in this new working group, contact EEMBC.

ULPBench – The Benefits of a DC/DC Converter

The ULPBench methodology utilizes an EEMBC EnergyMonitor to measure the energy of the device under test (DUT) while running through the benchmark’s duty cycle. The EnergyMonitor supplies 3V to the DUT. As all engineers know, input voltage has a direct effect on energy consumption. For a device that can operate in a range of 1.8V-3V, clearly it will benefit by operating at the lower voltage. An example of this is available on the EEMBC website – note the two scores for STMicro’s STM32L476RG’s. At 1.8V (utilizing an external DC/DC converter) and 3V, the device’s ULPBench results are 188 and 153, respectively. Some other devices shown in the results table also utilize buck converters to step down the EnergyMonitor’s 3V supply.

My Ruler Must Be Broken

This is the headline of a recent article by Jim Turley in EEJournal. In this article, Turley discusses the challenges of measuring power (energy) when dealing with device variance. To quote Turley, “Your MCU is like the old SR-71 spy plane, which was said to leak fuel on the runway because it was designed for supersonic speeds, where the air friction would heat the plane and cause it to expand, sealing the gaps. It was great at moving fast but leaked badly when sitting still.” Check out the article to read the details and the context of this quote.

EEMBC@Linley Data Center Conference

As you’ve seen from several announcements, EEMBC is working on ScaleMark, a benchmark suite to address cloud computing and the associated servers and SoCs. Markus Levy (EEMBC president) and Peter Torelli (EEMBC Director of Software Engineering) will be exhibiting and discussing ScaleMark at the Linley Data Center Conference coming to the Hyatt Regency Hotel, Santa Clara on February 9-10.

The Linley Data Center Conference is a two-day, single track event focused on the processors, components, and interconnects for data-center networking and servers.

  • Wednesday, February 9 (Conference: 9:00 a.m. - 4:00 p.m., Reception: 4:00 - 5:30 p.m.)
  • Thursday, February 9 (Conference: 9:00 a.m. – 3:00 p.m.)
  • Attendance is free to qualified attendees who register by February 4.

EEMBC@Embedded World

Planning to be in Nuremberg from February 23-25 attending Embedded World? Be sure to attend “Selecting Microcontrollers for IoT and Other Battery-Powered Applications,” presented by Markus Levy and Frank Riemenschneider, Editor in Chief, WEKA FACHMEDIEN, on February 23 from 9:30-10:00AM.

To complement this talk, engineers from STMicroelectronics (Francois Druilhe and Jean-Julien Pegoud) will present “Designing Wearable and Smart Power Efficient Applications” on February 23 from 12:00-12:30. This talk will apply the ULPBench methodology to explain MCU design techniques for high performance and low leakage current.

Throughout Embedded World, Levy will also be showing demonstrations of EEMBC’s upcoming IoT benchmark (contact EEMBC to schedule your appointment to check out this demo).
