Throughout history, people have compared the brain to different inventions. In the past, the brain has been said to be like a water clock and a telephone switchboard. This is hard to imagine, but it is what it is. But, these days, the favorite invention that the brain is compared to a computer. Some people use this comparison to say that the computer is better than the brain; some people say that the comparison shows that the brain is better than the computer. Perhaps, it is best to say that the brain is better at doing some jobs and the computer is better at doing other jobs.

So the question here arises is, how long is it going to take for the development of a machine that's as smart as we are? Well the good news is that we don’t have to wait any further for this now because man has already initiated his first step towards this dream project.
The year 2014 ended with a surprise. In the month of August,2014 IBM said it used conventional silicon manufacturing techniques to create what it calls a neurosynaptic processor that could rival a traditional supercomputer by handling highly complex computations while consuming no more power than that supplied by a typical hearing aid battery .The chip is also one of the biggest ever built, boasting some 5.4 billion transistors, which is about a billion more than the number of transistors on an Intel Xeon chip. To do this, researchers designed the chip with a mesh network of 4,096 neurosynaptic cores. Each core contains elements that handle computing, memory and communicating with other parts of the chip. Each core operates in parallel with the others.
The chip would seem to represent a breakthrough in one of the long-term problems in computing: Computers are really good at doing math and reading words, but discerning and understanding meaning and context, or recognizing and classifying objects — things that are easy for humans — have been difficult for traditional computers. One way IBM tested the chip was to see if it could detect people, cars, trucks and buses in video footage and correctly recognize them. It worked.
Down the road, the researchers say in their paper, they foresee TrueNorth-like chips being combined with traditional systems, each solving problems it is best suited to handle. But it also means that systems that in some ways will rival the capabilities of current supercomputers will fit into a machine the size of your Smartphone, while consuming even less energy.
The project was funded with money from the Department of Defense’s research organization. IBM collaborated with researchers at Cornell Tech and iniLabs. With TrueNorth’s truly novel architecture, that changes — with TrueNorth, IBM is now a big step closer to building a brain on a chip, and that could be big news for the future of computing.
