TrueNorth
TrueNorth is a neuromorphic CMOS chip produced by IBM.[1] It consists of 4096 hardware cores, each one simulating 256 programmable silicon "neurons" for a total of just over a million neurons. In turn, each neuron has 256 programmable "synapses" which convey the signals between them. Hence, the total number of programmable synapses is just over 268 million (2^28). In terms of basic building blocks, the chip hosts 5.4 billion transistors. Since memory, computation, and communication are handled in each one of the 4096 neurosynaptic cores, TrueNorth circumvents the von-Neumann-architecture bottlenecks and is very energy-efficient, boasting a power consumption of 70 milliwatts, about 1/10,000th the power density of conventional microprocessors.[2]
