Covering Science Each week the journal Science publishes a new issue filled with the top scientific research. Here’s the story behind the cover.
The structure of a modern computer chip still echoes the design ideas from 70 years ago - the parts that do the processing and the parts that store information are in separate sections. This works well for traditional computing task, but can underperform for tasks such as image processing.
Inspired by the structure and function of the mammalian brain, researchers from IBM and Cornell University have designed a new style of “neurosynaptic" chip. The chip is ~4 square centimeters and consists of 5.4 billion transistors, emulating a brain with 1 million “neurons” connected through 256 million pathways. The chip excels at visual processing and could be used in robots or for visually impaired people to help sense their surroundings.
