ROCK PI N10 RK3399Pro SBC Sells for $99 and up

Rockchip RK3399Pro processor is based on the popular Rockchip RK3399Pro hexa-core Arm Cortex-A72/A53 processor plus an embedded neural processing unit (NPU) delivering up to 3 TOPS for AI acceleration. So far you had to spend over $200 to get either Toybrick RK3399Pro board or 96Boards RK3399Pro development kit to get started with the processor. Some other companies announced their own RK3399Pro SBC such as Pine64 RockPro64-AI, or Khadas Edge board, but those are not available yet. But there’s now a more affordable Rockchip RK3399Pro SBC courtesy of Radxa’s Rock Pi N10 available on Seeed Studio in three variants: $99 model A with 4GB RAM (3GB for CPU/GPU + 1GB for NPU), 16GB eMMC flash $129 model B with 6GB RAM (4GB for CPU/GPU + 2GB for NPU), 32GB eMMC flash $169 model C with 8GB RAM (4GB for CPU/GPU + 4GB for NPU), 64GB eMMC flash Rock Pi N10 specifications: […]

Think Silicon NEOX|V is the First RISC-V ISA based GPU

We are seeing more and more RISC-V microcontrollers and processors hitting the market, but so far they all lacked a GPU for 3D graphics acceleration. Think Silicon, the make of NEMA GPU for IoT and wearables, has now announced it will demonstrate NEOX|V GPU, the first RISC-V ISA based 3D, at the RISC-V Summit at the San Jose Convention Center, on December 10-12, in San Jose, California. NEOX|V key features: Parallel multi-core and multi-threaded architecture based on the RISC-V64GC ISA instruction set with adaptive NoC (Networks-on-Chip) Configurable from 4 to 64 cores Variety of cache sizes and thread counts organized in 1 to 16 cluster elements Variety of cluster/core configurations with compute power ranging from 12.8 to 409.6 GFLOPS at 800 MHz Support for FP16, FP32, and FP64 plus SIMD instructions Beside 3D graphics, the RISC-V GPU can also be used for machine learning, vision/video processing, and open GPGPU compute […]

Sony Spresense 6-core MCU Development Board Now Supports Java

Sony Spresense board was introduced in spring 2018 with a 6-core Cortex-M4 microcontroller from the company, GPS & GLONASS, as well as audio support. The breadboard-compatible board could also be inserted into an Arduino UNO R3 compatible base board, and Sony offered support for both the Arduino IDE and a C-based NuttX-based SDK. You’ll find some more details and photos in our “review”. Sony has now partnered with MicroEJ to provide developers with Java support on Spresense board through MicroEJ Virtual Execution Environment (VEE). A Java simulator (VEE Virtual Device) allows you to develop software for Spresense independently of the hardware. Beside plenty of libraries, MicroEJ VEE features MEJ32 32-bit virtual core is compatible with various architectures including ARM Cortex-M, ARM Cortex-Ax, RX, V85, MIPS32, TriCore, and Tensilica. Java enables application portability which means that any GUI/IoT/Security or application code can run on various embedded systems supported by MicroEJ VEE. […]

Western Digital Made RISC-V Linux & BusyBox Boot on Sipeed Maix Go Board

The other day we wrote about Getting Started with Embedded Linux on RISC-V in QEMU emulator and noted that Linux capable RISC-V hardware is currently fairly expensive. We also mentioned there was work on porting uCLinux to Kendryte K210 RISC-V processor on boards such as Sipeed Maix board. The processor only comes with 8MB RAM, and does not feature an MMU (Memory Management Unit) so what you’d be able to do on the board would be limited, and for instance, a desktop environment is clearly impossible on the platform. NOMMU support also requires some extra work, and in Linux 5.4 we saw only of the changes was “SiFive PLIC IRQ chip modifications, in preparation for M-mode Linux”. The slide above is extracted from the “RISC-V NOMMU and M-Mode Linux” presentation by Damien Le Moal, Western Digital at the Linux Plumbers Conference 2019 last September. It explains M-mode support is better […]

Intel Austin Beach is a Modular, Fanless NUC Powered by Intel NUC Compute Elements

Intel Austin Beach NUC + Chandler Bay NUC Compute Element

Unveiled last May, Intel NUC Compute Element is a family of cards that should cost less than the failed Computer Cards, and easy to handle than your typical computer-on-module. The first Compute Elements showcased at Computex 2019 were powered by a 15-Watt Core U-series processor, and now various models will find their way into Intel Austin Beach fanless NUC with “Chandler Bay” NUC Compute Elements powered by Whiskey Lake processors. Intel Austin Beach specifications: Chandler Bay Compute Element (one or the other, all 15-W Whiskey Lake) BKCM8CCB4R – Intel Celeron 4305U 2-core/2-thread processor with 4GB LPDDR3, 64GB eMMC storage BKCM8PCB4R – Intel Pentium Gold 5405U 2-core/4-thread processor with 4GB LPDDR3, 64GB eMMC storage BKCM8i3CB4N – Intel Core i3-8145U 2-core/4-thread processor with 4GB LPDDR3 BKCM8i5CB8N – Intel Core i5-8265U 4-core/8-thread processor with 8GB LPDDR3 BKCM8v5CB8N – Intel Core i5-8365U 4-core/8-thread vPro processor with 8GB LPDDR3 BKCM8i7CB8N – Intel Core i7-8565U 4-core/8 […]

Run Raspberry Pi 4 Cooler with a New Firmware & One Easy Trick

Raspberry Pi 4 launched last June with a lot of buzz as it offered much better performance, more memory, and faster I/Os compared to Raspberry Pi 3 model B+. Benchmarks confirmed the improved performance but also revealed a heatsink was necessary to ensure optimal performance under heavy loads. Some companies also launched an oversized heatsink+fan combo for the board, but it’s really over the top and absolutely not necessary unless possibly in higher room temperature (50°C?). The Raspberry Pi Foundation also worked on improving the video to lower CPU temperature and power consumption, and a few days later released a beta version of VLI firmware that dropped the temperature by 3 to 5°C. Good effort but sadly the updated VLI firmware (used for the PCIe to USB controller) also had the side-effect of much slower USB performance. A new VLI firmware was released in September offering both a lower temperature […]
