$16 Banana Pi BPI-EAI80 Cortex-M4F Board Embeds AI Accelerator, WiFi Module

Last April, we wrote about Edgeless EAI-Series dual Arm Cortex-M4 MCU equipped with a 300 GOPS CNN-NPU for AI at the very edge as we had discovered the chip in an upcoming Banana Pi board. It turns out Banana Pi BPI-EAI80 development board powered by Edgeless EAI80 AI microcontroller has just launched for $16 on Aliexpress, or you could get a complete kit with a touchscreen display,  a camera, and a USB power supply for $80. Banana Pi BPI-EAI80 development board specifications: System-in-Package – Edgeless EIA80 dual-core Cortex-M4F microcontroller @ 200MHz with 300GOPS AI accelerator (CNN-NPU), 384KB of SRAM including 256KB for CNN-NPU, and 8MB SDRAM Storage – SPI flash Display I/F – LCD connector up to 1024×768 Camera I/F – 1x DVP camera interface Audio – 2x onboard microphones Connectivity – 2.4GHz 802.11b/g/n WiFI 4 using ESP8266 module USB – 1x USB 2.0 Type-C port Expansion 40-pin GPIO header (multiplexed with LCD interface) CANBUS 2.0 A/B header Debugging / […]

Ingenic T31 AI Video Processor Combines MIPS & RISC-V Cores

Last week we asked “is MIPS dead?” question following the news that Wave Computing had filed for bankruptcy, two MIPS Linux maintainers had left, and China-based CIP United now obtained the exclusive MIPS license rights for mainland China, Hong Kong, and Macau. Ingenic is one of those Chinese companies that have offered MIPS-based processors for several years, but one commenter noted that Ingenic joined the RISC-V foundation, and as a result, we could speculate the company might soon launch RISC-V processors, potentially replacing their MIPS offerings. But Ingenic T31 video processor just features both with a traditional Xburst  MIPS Core combines with a RISC-V “Lite” core Ingenic T31 specifications: Processors XBurst 1 32-bit MIPS core clocked at 1.5GHz with Vector Deep Learning accelerator based on SIMD128, 64KB + 128KB L1/L2 Cache RISC-V independent lite core System Memory – Built-in 512Mbit (64MB) or 1Gbit (128MB) DDR2 Storage – Quad SPI flash, NAND flash, SD card I/F Display I/F – Supports Smart […]

Getting Started with RT-Thread Nano RTOS on RISC-V Processors

CNXSoft: This is a guest post by RT-Thread explaining how to create your first program running on their real-time operating system using a GD32V  RISC-V MCU board as an example. This article describes how to “port” RT-Thread Nano to the RISC-V architecture, using the Eclipse IDE, GCC toolchain, and a basic project for the Gigadevice GD32V103 MCU. Foreword RT-Thread is an open-source embedded real-time operating system. RT-Thread has a standard version and a Nano version. The standard version consists of a kernel layer, components and service layer, and IoT framework layer, while the Nano version has a very small footprint and refined hard real-time kernel, better suited to resource-constrained microcontroller units (MCU). The main steps for porting Nano are as follows: Prepare a basic Eclipse project and get the RT-Thread Nano source code. Add the RT-Thread Nano source code to the base project and add the corresponding header path. Modify Nano, mainly for the interrupt, clock, memory, and application, to […]

Google Summer of Code 2020 Mentoring Organizations Announced

Every year Google organizes the Summer of Code inviting students to work on open-source projects and even get paid for it. The company first select mentoring organizations, before accepting applications from students. Google has now announced the 200 organizations/projects that have been selected for Summer of Code 2020. Many projects are higher-level software development such as web development or desktop programs development but there are also projects closer to the hardware-side of things with operating systems and multimedia projects. Some interesting organization and/or  projects part of the audio / graphics / video / multimedia category include: apertus Association developing AXIOM open-source hardware camera FFmpeg multimedia framework to decode, encode, transcode, de/mux, stream, filter & play audio and video stream found in many projects OpenCV Open Source Computer Vision Library for computer vision and deep learning applications. XOrg foundation for X Window System and related projects such as Mesa, DRI, Wayland, etc… Some operating systems part of GSoC 2020 include: Amahi […]

GigaDevice Releases GD32V RISC-V MCU and Development Boards

GD32VF103 RISC-V General Purpose MCU

A few years ago, we came across GigaDevice GD32 microcontroller compatible with STMicro STM32F103, but with a higher 108 MHz clock, and zero wait state internal flash. The MCU was also a drop-in replacement for the STMicro alternative since beside being software compatible, it was also pin-to-pin compatible. The company is now back with a new microcontroller, but it’s not Arm-based. Instead, GigaDevice GD32V is based on RISC-V open source architecture. GD32V General Purpose RISC-V MCU GigaDevice GD32V is a 32-bit RISC-V general-purpose MCU that targets industrial and consumer applications such as IoT, edge computing, artificial intelligence and “vertical industries”. The new GD32VF103 series RISC-V MCU family features 14 models with the following key specifications: Core – GD32VF103 32-bit rv32imac RISC-V “Bumblebee Core” @ 108 MHz Memory – 8KB to 32KB SRAM Storage  – 16KB to 128KB flash Peripherals – USB OTG and CAN 2.0B I/O – 3.3V, 5V tolerant Supply Voltage – 2.6 to 3.6V Package – QFN36, LQFP48, […]
