'''Sophon BM1880''' is a [[neural processor]] designed by [[Bitmain]] launched in [[2018]] for edge applications. This chip is designed primarily for edge inference acceleration and has a peak performance of [[peak integer ops (8-bit)::2 TOPS]] (INT8) and a typical power consumption of 2.5 W.

== Overview ==
The BM1880 is a [[neural processor]] designed for edge inference at low power consumption. The chip integrates a single-core [[RISC-V]] MCU subsystem operating at 1 GHz along with a dual-core {{armh|Cortex-A53|l=arch}} application processor operating at 1.5 GHz along with a TPU subsystem by BitMain capable of up to 2 teraOPS (8-bit integer). The chip also includes a capable video subsystem for video and image processing from a camera directly on-chip.
