TrueNorth has 5.4-billion-transistors with 4096 neurosynaptic cores interconnected via an intrachip network that integrates 1 million programmable spiking neurons and 256 million configurable synapses.
It can be tiled in two dimensions through an interchip communication interface and can be scaled up to a cortexlike sheet of arbitrary size.
The chip has been fabricated on Samsung’s 28nm process and claimed to be IBM’s largest chip in terms of transistor count.
During the simulation of complex recurrent neural networks, the chip consumes less than 100mW of power and has a power density of 20mW / cm2.
IBM fellow Dharmendra Modha said: "Unlike the prevailing von Neumann architecture — but like the brain — TrueNorth has a parallel, distributed, modular, scalable, fault-tolerant, flexible architecture that integrates computation, communication, and memory and has no clock.
"It is fair to say that TrueNorth completely redefines what is now possible in the field of brain-inspired computers, in terms of size, architecture, efficiency, scalability, and chip design techniques."
The chip can be used in many applications that use complex neural networks in real time including multi-object detection and classification.
