Elektronik Analyzes Ultra-Low Power Microcontroller ClaimsDr. Claus Kühnel (Director Head of Embedded Systems at QIAGEN Instruments AG) and Frank Riemenschneider (editor-in-chief of Design & Elektronik) tested the claims of the ‘ultra-low power marketing messages’ of every well-known MCU vendor. This exercise was performed within Elektronik as an Elektronik-Projekte, a unique set of articles with deep technical focus. With the support of each vendor, Claus and Frank configured the microcontroller boards, built the EEMBC ULPBench software, and utilized EEMBC EnergyMonitor to make measurements. Their results were originally published in Elektronik 16/2015, starting on page 26 on August, 11th. Available to read in several languages: Tom’s Hardware Describes Mobile Device Benchmarking ProcessIn this article, Tom’s Hardware Editor, Matt Humrick, explains their strict testing procedures used to obtain accurate benchmark data on smartphones and tablets. This article is definitely one of the more elaborate explanations of benchmarking procedures I’ve ever seen. Furthermore, it’s cool that EEMBC’s AndEBench-Pro is a key component of this testing.

This is aligned with what was reported by Atmel in their own measurements, showing the robustness of the ULPBench EnergyMonitor and setting a new high score for certified ULPBench results. The SAM L21 is Flash based and uses an Atmel-developed ultra-low power process in combination with power islands, caches, and efficient regulators. Having a benchmark that allows you to compare power consumption across CPU cores and memory technologies is unique to ULPBench and a great yardstick for developers in the early stages of device evaluation. STMicroelectronics STM32L476RG – The certification, yielding a score of 153, was performed on the identical microcontroller+board that STMicro used when they independently submitted the ULPBench result of 123.5. Why do these two results differ by 23%? The compiler. With the former, ST used the IAR C/C++ compiler for ARM (v6.60.1.5097), while the latter utilized ARMCC (5.04.0.49). Stating the obvious – with ULPBench, the compiler choice will affect the benchmark’s active mode component. IoT Benchmark Project Moves ForwardIn May, EEMBC announced its new IoT working group focused on benchmarks to allow application developers to quickly and equitably compare the efficiency of systems targeted at IoT edge nodes. The initial benchmark profiles will focus on microcontrollers, low-power Bluetooth and ZigBee devices, modules, and software stacks. The working group chairs (Mark Wallis of STMicro and Brent Wilson of Silicon Labs) encourage all interested parties to join this working group to help determine the details of this IoT benchmark and ensure the benchmarks are representative of all possible scenarios.

ScaleMark: EEMBC’s Benchmark Suite for Cloud and Scale-out Servers Enters Beta StageEEMBC Beta version of its new cloud and scale-out server benchmark suite, ScaleMark, is almost ready. It focuses on web caching and media streaming. This suite addresses the needs of ODMS, OEMS, and cloud and big-data users who deploy their applications in large distributed computer centers made up of clusters of servers. The industry has lacked a reliable, repeatable, portable, and architecture-neutral method to evaluate the latency and throughput of SoCs and associated servers for real-world cloud and big-data applications running at data centers – that all changes with ScaleMark. Interested in becoming a Beta tester (no charge) for ScaleMark? Contact Markus Levy Linaro ConnectSeptember 23rd is the LEG ARM Server Ecosystem Day at Linaro Connect. Markus Levy (EEMBC) and Bryan China (Cavium) will present “Understanding Performance Results for Servers in the Data Center.” Linley Processor ConferenceThe Linley Group will hold its annual processor conference on October 6-7 in Santa Clara, CA. EEMBC is exhibiting, so stop by and check out our benchmark updates. Renesas DevConThe biennial Renesas DevConOn will be held in Orange County from October 12-15. EEMBC will be exhibiting and demoing its EnergyMonitor and ULPBench and discussing its upcoming IoT benchmark. EEMBC president, Markus Levy, also joins an illustrious panel of speakers for the topic of IoT security. Light Reading’s Next Generation Network Components Join Light Reading on November 5 in Santa Clara for a day of presentations and demonstration of Next Generation Network Components. EEMBC will be there with a tabletop exhibit. ARM TechConBryan Chin (Cavium) and Markus Levy will co-present “How (Not) to Generate Misleading Performance Results for ARM Servers“ at the ARM TechCon, taking place November 10-12 at the Santa Clara Convention Center.
