The new chip from IBM is almost human brain?

With the launch of the new TrueNorth chip with 5.4 billion transistors, IBM said it would open a new era in the development of chips acting as the human brain.

According to analysts, even when packing multiple processor cores in conjunction with other forms of memory storage, the new computing technology could hardly close to the power of the human brain. The human brain has about 100,000 billion synapses, a neural network requiring 96 Lawrence Livermore National Lab Sequioa supercomputers  to simulate, and even then only supercomputers can perform simulation with speed 1,500 times slower than the brain.

A computer needs a lot of energy for this function because it can not catch what the human mind is capable of performing, but a computer program can make all the calculations and complex reactions. The goal of the IBM  project is to create an computer that could simulate vision and have the closest response the human brain, and TrueNorth is the technology that IBM consider may closer to the possibility of brain.

TrueNorth chip is a part of IBM's efforts that the company developed in 2008 with the objective of producing a new form of computing architecture based on nerve cells and neural networks of the brain. Instead of simply performing calculations on 4 or 8 cores as quickly as possible, TrueNorth chip can get samples and promote to handle data more effectively with the help of the 4096 inner cores.

These cores are unlike present one, and how they work are also different. Instead of running all at the same time, each core will run only when necessary to save power and reduce heat generated. All cores are communicated over a network in which the system can scale up work, the core may stop working and everything will continue to operate as needed without disruption.

4096 cores work like representing  a million nerve cells and 256 million synapses. This chip has not been compared to the 10 billion neurons and 100,000 billion nerve layers in the human brain, which is the ultimate goal of the project came from IBM.
