Microprocessors are evolving to mimic the way the brain is designed. We are just witnessing the beginning of highly sophisticated microprocessors that emulate the biological neural network´s architecture with digital neurons, synapses, axons, etc….
IBM recently introduced to the market a new experimental neurosynaptic computer chip that emulates brain function in areas like cognition, perception and action. These new chips will use algorithms and silicon circuitry in order to recreate spiking neurons and synapses in the brain. IBM has developed two (02) working prototypes that are currently undergoing testing.
Both cores have 256 neurons and were fabricated in 45 nm SOl-CMOS. One core has 262,144 programmable synapses while the other contains 65,536 learning synapses. Researchers have already achieved applications like machine vision, associative
memory, classification, navigation and pattern recognition.
Following IBM´s Neuromorphic path, Intel’s Circuit Research Laboratory in Hillsboro, Oregon, USA announced the design of a neuromorphic chip based on two technologies: lateral spin valves and memristors. Spin-based neuromorphic designs can achieve 15X-300X lower computation energy. Intel’s goal is to build chips that work more like the human brain.
Through silicon circuitry and advanced algorithms along with principles of neuroscience, nanoscience and supercomputing, these chips are capable of imitating biological processes such as those occurring in the human brain.
