IBM new chip works almost like a human brain
Posted by Abby Smith on 9th August 2014

IBM revealed the SyNAPSE, a CPU that acts like a human brain, having infinite capabilities. Neurons and synapses: words that deal with organic life forms. It’s a type of advanced chip that operates, in the same way, the mammalian brain does.
In other words, IBM is developing CPUs that traditionally operate like the right side of the brain, which have the capability of processing language and analytical thinking while the opposite side handles all the senses and pattern recognition.
Dharmendra Modha, chief scientist of IBM Research, stated “It’s a new landmark of the brain-inspired computers.”
The chip is of the size of a postage-stamp, rigged with 5.4 billion transistors that are efficient of stimulating one million neurons in addition to 256 million neural connections, or synapses.
“We have not built a mind. What we have done is learn from the brain’s anatomy and physiology,” stated research study leader Dharmendra Modha.
Modha explained how brain like chip differs from traditional computer chip by comparing them. He thought classical computer as a left-brained machine which is fast, sequential and good at numbers. “What we’re building is the counterpart, right-brain machine,” Modha told Live Science.
A “brain-influenced” chip
The latest technology, IBM’s new chips design resemble of a living brain. The chip is composed of 256 input lines or “axons” connected to each computing cores and 256 output lines, or “neurons.” It’s more like a real brain, and artificial neurons send signals, or spikes, when electrical charges reach a certain verge.
The research team connected more than 4000 of these cores on a chip, and tested it with complex image recognition task that is to detect people, bicyclists, and to identify each object correctly.
“This is [the] work of a gigantic team, working across many years,” Modha stated. “It was a multidisciplinary, multi-institutional, multiyear effort.”
Although, the IBM chip is far away from human brain, which has more than 86 trillion neurons and 100 trillion synapses.
