Research led by computer science professors Michael Taylor and Steven Swanson is covered in Technology Review today by Tom Simonite.
The first paragraph from the Technology Review GreenDroid project is below:
A processor etched with circuits tailored to the most widely used apps on Android phones could help extend the devices' battery life. Researchers at the University of California, San Diego have created software that scans the operating system and a collection of the most popular apps and then generates a processor design tailored to their demands. The result can be 11 times more efficient than today's typical general-purpose smart-phone chip, says Michael Taylor, who leads the GreenDroid project with colleague Steven Swanson.The Jacobs School covered this work back in August when the UC San Diego computer scientists presented at HotChips 2010.
The first two paragraphs of the Jacobs School of Engineering GreenDroid story are below:
A new smartphone chip prototype under development at the University of California, San Diego will improve smartphone efficiency by making use of “dark silicon” – the underused transistors in modern microprocessors. On August 23, UC San Diego computer scientists presented GreenDroid, the new smartphone chip prototype at the HotChips symposium in Palo Alto, CA.
Dark silicon refers to the huge swaths of silicon transistors on today’s chips that are underused because there is not enough power to utilize all the transistors at the same time. The new GreenDroid chip prototype from computer scientists at UC San Diego will deliver improved performance through specialized processors fashioned from dark silicon. These processors are designed to run heavily used chunks of code, called “hot code,” in Google’s Android smartphone platform.
