Bonsai Algorithm Enables Machine Learning on Arduino with a 2KB RAM Footprint

Machine learning used to be executed in the cloud, then the inference part moved to the edge, and we’ve even seen micro-controllers able to do image recognition with GAP8 RISC-V micro-controller. But I’ve recently come across a white paper entitled “Resource-efficient Machine Learning in 2 KB RAM for the Internet of Things” that shows how it’s possible to perform such tasks with very little resources. Here’s the abstract: This paper develops a novel tree-based algorithm, called Bonsai, for efficient prediction on IoT devices – such as those based on the Arduino Uno board having an 8 bit ATmega328P microcontroller operating at 16 MHz with no native floating point support, 2 KB RAM and 32 KB read-only flash. Bonsai maintains prediction accuracy while minimizing model size and prediction costs by: (a) developing a tree model which learns a single, shallow, sparse tree with powerful nodes; (b) sparsely projecting all data into […]

UDOO BOLT AMD Ryzen Embedded V1000 SBC Goes for $229 and Up (Crowdfunding)

While Intel has been outing low cost and low power processors with less than 10W TDP over the years with their Bay Trail, Cherry Trail, Braswell, Apollo Lake, and now Gemini Lake processors, AMD has not really ventured into the low power space, and the latest announcements about 10-12W processors was for their Embedded G-Series J Family, which I have not seen in many products. More recently, the company introduced Ryzen Embedded V1000 family of processors with 4 to 8 Zen cores, 4K support, 10 GbE interface, and more with a TDP of 12 to 25W for Ryzen Embedded V1202B & V1605B dual / quad core processors. The latest x86 UDOO board – dubbed UDOO BOLT – will be one of the rare AMD development boards available on the market with pricing starting at $229. Two versions of the board will be available: UDOO BOLT v3 with Ryzen Embedded V1202B, […]

Circumference Datacentre-in-a-Box Features up to 32 Raspberry Pi 3 B+ Managed by a UDOO x86 Ultra Board (Crowdfunding)

We’ve previously seen several clusters made of Raspberry Pi boards with a 16 RPi Zero cluster prototype, or BitScope Blade with 40 Raspberry Pi boards. The latter now even offers solutions for up to 1,000 nodes in a 42U rack. Circumference offers an other option with either 8 or 32 Raspberry Pi 3 (B+) boards managed by UDOO x86 board acting as a dedicated front-end processor (FEP) that’s designed as a “Datacenter-in-a-Box”. Key features and specifications: Compute nodes – 8x or 32x Raspberry Pi 3 B+ boards for a total of 128x 64-bit 1.4 GHz cores max Backplane MCU – Microchip ATmega1280 8-bit AVR microcontroller Serial Comms – FTDI FT4232 quad-USB UART Switched Mode Power Supply Units (SMPSUs): 8x / 32x software controlled (one per compute node) 1x / 4x always-on (microcontroller) HW monitoring: 8x / 32x compute node energy 2x / 8x supply voltage 2x / 8x temperature Remote […]

$1.40 EDMINI Development Board Features LogicGreen LGT8F328P MCU Compatible with ATMega328P/Arduino

Arduino compatible boards are normally using Microphip Atmel microcontrollers, but as we’ve see with GD32 clone of STM32 MCU, some companies are making MCU clones too, usually with some improvements, and LogicGreen designed LGT8F328P micro-controller (mostly) compatible with Atmel ATMega328P micro-controller and adding features such as DAC output, PWM specific features, a computing accelerator (DSC), and others. The MCU also runs at double the clock speed (32 MHz). I found out about the new MCU via Electrodragon selling EDMINI Arduino compatible development board based on LGT8F328P micro-controller for $1.40. The board looks to be a clone of Arduino Pro Mini. Main specifications for EDMINI board: MCU – LogicGreen 8F328 (LGT8F328P) MCU – 99% compatible with ATMEGA328P MCU Expansion – Same pins as Arduino Pro Mini plus SWD/SWC pins, PE4/PE5 pins Misc – On-board power LED, D13 LED, reset button Power Supply – 5V RAW as VCC directly in; regulated 3.3V […]
