Power/Performance Bits: Sept. 13


Core-to-core communication Most research featured in the Power/Performance Bits has far-off applications, but a team from North Carolina State University and Intel developed something that could be brought into practice today: a way to accelerate core-to-core communication. Many important workloads incur significant core-to-core communication and are affected significantly by the costs, i... » read more

The Trouble With MEMS


The advent of the Internet of Things will open up a slew of new opportunities for MEMS-based sensors, but chipmakers are proceeding cautiously. There are a number of reasons for that restraint. Microelectromechanical systems are difficult to design, manufacture and test, which initially fueled optimism in the MEMS ecosystem that this market would command the same kinds of premiums that analo... » read more

Power/Performance Bits: March 29


Photonic-phononic circuit Researchers at the National Institute of Standards and Technology (NIST) developed a piezo-optomechanical circuit that converts signals among optical, acoustic and radio waves. At the heart of the piezoelectric optomechanical circuit is an optomechanical cavity, which consists of a suspended nanoscale beam. Within the beam are a series of holes that act like a ha... » read more

Manufacturing & MEMS


By Joanne Itow There’s been a lot of attention focused on MEMS in the past couple of years, and rightfully so. In 2011 when total semiconductor revenues grew by only 1.3%, MEMS revenues grew by more than 34%. MEMS have been activating air bags in our cars and projecting images on DLP screens for years, but it wasn’t until the accelerometer in smartphones when mainstream semiconductor manuf... » read more
