CM1K, neuromorphic chip with 1024 neurons


The CM1K is a neuromorphic chip opening new frontiers for smart sensors and cognitive storage. It can learn and recognize patterns extracted from text, measurement, images and signals with orders of magnitude less energy and complexity than modern microprocessors.

In addition, the CM1K has digital video input port directly connected to a built-in recognition logic which subsamples a region of interest and broadcasts it after each frame to the neurons for immediate recognition.

The default interface to the chip is a 26-pins bidirectional bus, but the CM1K also features an I2C I/O port for a slower but easier access to the neurons.
