Sophon is a family of low-power neural processors designed by Bitmain.

Overview

Announced in late 2017 at the AIWORLD 2017 Artificial Intelligence Conference in Beijing, Sophon is a family of low-power neural processors. Bitmain started exploring the field of artificial intelligence and neural processors as early as 2015. By April 2017, their first product, the BM1680, has taped-out. Their chips are designed for both inference and training of neural networks, suitable for working with the common ANNs such as CNN, RNN, and DNN.
