Loihi 2 (pronounced low-ee-hee 2) is the successor to Loihi, a second-generation neuromorphic research test chip designed by Intel Labs that was introduced in late 2021. The chip uses an asynchronous spiking neural network (SNN) to implement adaptive self-modifying event-driven fine-grained parallel computations used to implement learning and inference with high efficiency. The chip is a 128-neuromorphic cores many-core IC fabricated on Intel 4 process and features a unique programmable microcode learning engine for on-chip SNN training.
