The drastic reduction in the design effort is highly beneficial in cost-sensitive silicon systems, such as sensors for the Internet of Things (IoT). The novel data converter architecture also has very low complexity, reducing the silicon area and hence the manufacturing cost by at least 30 times, compared to conventional designs. </p> <p class="has-black-color has-text-color">Read more on: <a href="https://www.eng.nus.edu.sg/ece/news/nus-innovation-paves-the-way-for-sensor-interfaces-that-are-30-times-smaller/">https://www.eng.nus.edu.sg/ece/news/nus-innovation-paves-the-way-for-sensor-interfaces-that-are-30-times-smaller/</a></p> ]]></content:encoded> <post-id xmlns="com-wordpress:feed-additions:1">481</post-id> </item> <item> <title>First microprocessor with energy-performance tradeoff wider than voltage scaling for faster operation and longer battery life</title> <link>https://green-ic.org/CogniVision/news/first-microprocessor-with-energy-performance-tradeoff-wider-than-voltage-scaling-for-faster-operation-and-longer-battery-life/?utm_source=rss&utm_medium=rss&utm_campaign=first-microprocessor-with-energy-performance-tradeoff-wider-than-voltage-scaling-for-faster-operation-and-longer-battery-life</link> <dc:creator><![CDATA[Hephzibah Solomon]]></dc:creator> <pubDate>Fri, 22 May 2020 08:42:20 +0000</pubDate> <guid isPermaLink="false">https://green-ic.org/CogniVision/?post_type=news&p=483</guid> <description><![CDATA[A team of researchers from NUS have invented a novel class of reconfiguration techniques that adaptively extends both the minimum power consumption and the maximum performance of digital circuits, well beyond common voltage scaling.

Such extended adaptation allows digital silicon chips to operate at lower power during normal use, and at higher performance level when necessary. </p> <p class="has-black-color has-text-color">This extends the battery life under uncertain power availability in systems powered by harvesters (e.g. solar cell) or rechargeable batteries, while delivering higher peak performance to carry out on-chip data analytics upon the occurrence of events of interest. This is a key enabler for applications such as Internet of Things (IoT), artificial intelligence (AI), wearables and biomedical devices. </p> <figure class="wp-block-image size-full"><img data-recalc-dims="1" decoding="async" width="400" height="225" src="https://i0.wp.com/green-ic.org/CogniVision/wp-content/uploads/2022/03/cognivision-news_silicon-chips-faster-and-longer.jpg?resize=400%2C225&ssl=1" alt="" class="wp-image-484" srcset="https://i0.wp.com/green-ic.org/CogniVision/wp-content/uploads/2022/03/cognivision-news_silicon-chips-faster-and-longer.jpg?w=400&ssl=1 400w, https://i0.wp.com/green-ic.org/CogniVision/wp-content/uploads/2022/03/cognivision-news_silicon-chips-faster-and-longer.jpg?resize=300%2C169&ssl=1 300w" sizes="(max-width: 400px) 100vw, 400px" /><figcaption>Assoc Prof Massimo Alioto (centre) and his team members Lin Longyang (left) and Saurabh Jain (right) showing off the prototyping boards for testing the silicon chips to demonstrate highly flexible power and performance, surpassing industry</figcaption></figure> <p class="has-black-color has-text-color">“Our reconfiguration techniques introduce unprecedented adaptability to fluctuating power availability and performance demand. Compared to the industry-standard voltage scaling technique, measurements on several test chips in our lab have shown that such adaptation extends the battery life of a mobile or wearable device by 1.5 times, while doubling peak performance. Our techniques can also be used to further miniaturise the battery by the same factor, while maintaining the same battery life,” explained Associate Professor Massimo Alioto, from <a href="http://www.eng.nus.edu.sg/" target="_blank" rel="noreferrer noopener">NUS Engineering</a>.
