IBM Chip BrainIBM Chip Brain, IBM today announced the creation of a computer chip that mimics the way the brain receives and interprets information. The discovery, which was conducted by a team of scientists from four universitys, IBM, and the Defense Advanced Research Projects Agency (DARPA), was an important step in finding long term to create an artificial machine that emulates the brain.

┬áIt’s called cognitive computing chip, drive, a small core of computing that will be repeated again and again to build a brain similar to the current team.

The project, called synapses (adaptive neuromorphic electronic systems scalable plastic) with scientists at Columbia University, Cornell University, the University of California at Merced, and the University of Wisconsin, IBM and DARPA. Synapses and received a grant of 21 million today DARPA, which provides funding and a total of 41 million. With the money, Synapse will work to build a brain-computer like, which would break the world into a paradigm of advanced computing.

According to VentureBeat, the new model computer unit to function as a piece of the brain would be. Containing neurons, which are digital processors to calculate the information, the synapses, the fire to pass information, learning and memory hold, and axons, which are pathways that connect data to the computer tissues.

Working together, these amount parties to a major break with the traditional method of computing. Until now, computers have been based on the von Neumann architecture computer, named for the computer scientist who invented it. Von Neumann’s method is sequential, but pushes the data processor to the memory storage through a small tube called a bus. It is a step-by-step method, although fast, is subject to limitations. Trying, for example, to force too much data over the bus may result in the bottleneck of von Neumann, which is like a traffic jam between the processor and memory.

By contrast, the human brain lays the burden of processing and delivery of information to memory. Instead of sending the data step by step through a tube, the brain transmits signals simultaneously in all directions, allowing the neurons, synapses and axons to work together. Thus, the brain can process vast amounts of complex information quickly and with little power consumption. It is this type of computer system that emulates the cognitive chip.

The first chip is rudimentary compared with treatment of complex brain. In the near future, however, the chips should be much better able to perform brain-like activities of computers today. Activities such as recognizing patterns, creating hypotheses, and learning through the experience will improve. Computers built with these chips are reconfigured constantly imitating the “plasticity” of an organic brain. And it uses much less energy.

Dharmendra Modha, project leader of the synapse, he said, for example, that a computer could take detailed measurements cognitive sensory water temperature, atmospheric pressure and ocean tides and use that information to warn people of impending hurricanes or tsunamis. In another example, Stefano Fusi, Columbia University, said the team, mimicking the brain’s sensoryanlysis of a bird could fly a plane without a pilot through a hanger at a speed of 1,000 kilometers per hour.
