IoT For Building Energy Systems In Zero-Emission Buildings


By Dirk Mayer and Olaf Enge-Rosenblatt How can buildings contribute to a significant reduction in global primary energy consumption? Due to the global trend toward reducing CO2 emissions and resource conservation, the demands are increasing with regard to the efficiency of heating, ventilation and air-conditioning (HVAC) systems operated in buildings. In conflict with calls for fas... » read more

Focus Shifts To Wasted Power


Mobile phones made the industry aware of power, but now the focus is shifting to the total energy needed to perform a task. Activity that is unnecessary to perform the intended task is wasted power, and reducing it requires some new methodologies and structural changes within development teams. There is a broadening awareness about power. "The companies doing SoCs for mobile lead the charge ... » read more

Taking Energy Into Account


Considering power throughout the SoC design flow is common practice. The same cannot be said for energy, although that is beginning to change as chips increasingly incorporate heterogeneous processing elements. Combined with this, AI/ML/DL technologies increasingly allow engineering teams to explore and optimize design data for more targeted and efficient systems. But this approach also requ... » read more

DRAM Tradeoffs: Speed Vs. Energy


Semiconductor Engineering sat down to talk about new DRAM options and considerations with Frank Ferro, senior director of product management at Rambus; Marc Greenberg, group director for product marketing at Cadence; Graham Allan, senior product marketing manager for DDR PHYs at Synopsys; and Tien Shiah, senior manager for memory marketing at Samsung Electronics. What follows are excerpts of th... » read more

The Limits Of Energy Harvesting


Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

Energy At The Edge


Ever since the first mention of the IoT, everyone assumed there would be billions of highly efficient battery-powered devices that drew milliwatts of energy. As it turns out, we are about to head down a rather different path. The enormous amount of data that will be gathered by sensors everywhere cannot possibly be sent to the cloud for processing. The existing infrastructure cannot handle i... » read more

Tech Talk: Near-Threshold Power


Lauri Koskinen, CTO and founder of Minima Processor, and Ron Moore, vice president of marketing at ARM, talk about near-threshold computing, dynamic power and margining, and how these techniques can extend battery life and reduce energy consumption. https://youtu.be/BhiNFe4NYQU » read more

New Materials For Computing


The U.S. Department of Energy rolled out a new program to develop materials for "extreme conditions" for high-performance computing, setting the stage for much more mobile versions of AI and machine learning. This effort, if successful, has interesting implications on a number of levels. For one, the DOE's mandate includes everything from energy security to weaponry, and high-performance com... » read more

Sustainability Saves Water, Too


After energy (discussed in Part 2 of this series), water is the largest fab input and the largest contributor to fab waste. Yet tools for analyzing a fab’s water footprint are generally less mature than tools for analyzing emissions of CO2 and other greenhouse gases. In part, this may be because water consumption is primarily a local issue, while greenhouse gas emissions are a global c... » read more
