Introduction

Module type

Firefly Neural Network Computing Card is launched by Firefly, is a
serial of NPU (Neural Processing Unit) module that work with Firefly’s
development board. The module is equipped with the lightspeeur 2801S
chip launched by GTI (full name is Gyrfalcon Technology Inc.). 2801S’s
peak computing capacity is 2.8 Tops. It can complete 9.3 TOPS (tera
operations per second) per watt consumed.

Firefly Neural Network Computing Card has three types: NCC S1 module,
USB Dongle module and embedded module.

1. NCC S1 module

NCC S1 module’s interface is eMMC, which can be used along with ROC-
RK3399-PC.

It is small that suitable for the use in the products.

NCC S1

2. USB Dongle module

USB Dongle module’s interface is USB, which can be employed
universally in every Firefly’s development board.

Used for inferencing in model training.

USB Dongle

3. Embedded module

Connected via USB 3.0

Module built-in development board

Device node is same as USB Dongle

Support system

Ubuntu 16.04

Android (USB Dongle and AIO-3399C AI version)

Support development board

NCC S1 supports development board
