(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 Cortex-A53 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.
