TrueNorth
Lua error in package.lua at line 80: module 'strict' not found.
TrueNorth is a neuromorphic CMOS chip produced by IBM.[1] It is a manycore network on a chip design, with 4096 cores in the current chip, 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, its transistor count is 5.4 billion. Since memory, computation, and communication are handled in each of the 4096 neurosynaptic cores, TrueNorth circumvents the von-Neumann-architecture bottlenecks and is very energy-efficient, consuming 70 milliwatts, about 1/10,000th the power density of conventional microprocessors.[2] The SyNAPSE chip (introduced mid 2014) operates at lower temperatures and less power because it operates only when it needs, rather than all the time.[1] Scottprovost (talk) 08:32, 28 May 2016 (UTC)
