EEMBC Undertakes Development of Industry-Standard Ultra-Low Power Microcontroller Benchmarks
The Embedded Microprocessor Benchmark Consortium (EEMBC) today announced its intent to create a standardized, industry-endorsed method to evaluate the energy efficiency of ultra-low power (ULP) microcontrollers. To date, the industry has lacked a common method to test, validate, and compare the real-world energy consumption of these microcontrollers that target applications such as portable medical devices, security systems, building automation, smart metering, and also applications using energy harvesting devices.

Unlike other EEMBC benchmarks that endeavor to measure the top performance of processors and systems, the ULP benchmark will focus on measuring the energy consumed by microcontrollers running various computational workloads over an extended time period. The benchmarking methodology will allow the microcontrollers to enter into their idle or sleep modes during the majority of time when they are not executing code, thereby simulating a real-world environment where products must support battery life measured in months, years, and even decades.
Horst Diewald, chief architect of MSP430™ microcontrollers at Texas Instruments (TI), has accepted the role as chair of the EEMBC ULP working group. "We have seen a significant need for a well-constructed, industry-accepted benchmark to equitably evaluate the energy efficiency of microcontrollers," commented Mr. Diewald. "Unfortunately, the application developer cannot rely on datasheet parameters alone to compare total microcontroller power consumption and select an appropriate microcontroller. This is the reason I am honored to chair this important working group."

"EEMBC's primary goal is to develop fair and unbiased benchmarks for the embedded industry. In support of this goal, I am very excited that the EEMBC members are so motivated to develop this much-needed ULP benchmark," said EEMBC president Markus Levy. "In the system developer's interest, we encourage all relevant companies, including the system manufacturers, microcontroller vendors, and tool providers, to join us in this effort."
EEMBC was formed in 1997 to develop performance benchmarks for the hardware and software used in embedded systems. EEMBC benchmarks help predict the performance and energy consumption of embedded processors and systems in a range of applications (i.e. automotive/industrial, digital imaging and entertainment, networking, office automation, telecommunications, and connected devices) and disciplines (processor core functionality, floating-point, Java, multicore, and energy consumption). The consortium's popular CoreMark benchmark was recognized by Jack Ganssle in Embedded.com as one of the top ten milestones in embedded 2012.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
