96-Core NanoPi Fire3 Boards Cluster is a DIY Portable Solution to Teach or Develop Distributed Software

Nick Smith has been messing around with clusters made of Arm boards for several years starting with Raspberry Pi boards, including a 5-node RPI 3 cluster, before moving to other boards like Orange Pi 2E, Pine A64+, or NanoPC-T3. His latest design is based on twelve NanoPi Fire3 boards with 8 cores each, bringing the total number of cores to 96. The platform may not be really useful for actual HPC applications due to limited power and memory, but can still be relied upon for education and development, especially it’s easily portable. Nick also made some interesting points and discoveries. It’s pretty with shiny blinking LEDs, and what looks like proper cooling, and the cluster can deliver 60,000 MFLOPS with Linpack which places it in the top 250 faster computers in the world! That’s provided we travel back in time to year 2000 through 🙂 By today’s standard, it would […]

Arm Compares Arm & RISC-V Benefits in RISCV Basics Website

Arm is a dominant force in mobile and embedded processors, but recently we’ve heard more and more about RISC-V open source and royalty-free alternatives, and for example SiFive has launched both application processors / IP with solutions like Linux capable Freedom U540 SoC found in HiFive Unleashed board, as well as RISC-V MCU Cores competing with Arm Cortex-M4 and Cortex-M0+ cores. There’s certainly a lot of activity around RISC-V, but I have not seen many commercial solutions yet, and the platform needs to mature. However, Arm apparently takes the competition seriously with the company setting up a website – riscv-basics.com – comparing Arm and RISC-V, notably through the infographics below. Arm recognizes RISC-V has no recurring license fees, but claims those fees are only a small fraction of the total investment required for a commercial processor. The company also questions RISC-V maturity, and at this stage is may be true, […]

Makerdiary nRF52840 Micro Development Kit Works with OpenThread, Arm Mbed OS, Zephyr OS, Mynewt, etc…

If you want to play around with Bluetooth 5, Nordic nRF52840 is probably one of the best option, and among the development board, $9/$12 Particle Xenon is hard to beat when it comes to value. But if you need a bit more storage, I/Os and features, Makerdiary nRF52840 micro development kit looks like a good candidate to evaluate, especially it supports plenty of frameworks / operating systems such as Arm Mbed OS, Zephyr Project, OpenThread, Mynewt, and others. It’s also the first MCU class board I’ve seen with a USB type C port, although I’m not sure it brings any benefits to this type of hardware. Makerdiary nRF52840 micro development kit (nRF52840-MDK) hardware specifications: SoC – Nordic nRF52840 Arm Cortex-M4F WiSoC with 1 MB FLASH and 256 kB RAM, Arm TrustZone Cryptocell 310 security subsystem External Storage – 64-Mbit QSPI flash Wireless Connectivity (on-chip) Bluetooth 5, Bluetooth Mesh Thread, IEEE […]

Visual Studio 2017 with an Embedded Linux Arm Device

This is a non-sponsored guest post written by Marc Goodner: Principal Program Manager, Microsoft, and Jeremias Cordoba: Innovation Engineer, Toradex. Today many embedded devices run some flavor of Linux as their primary operating system. This poses a challenge to developers who run Windows on their development machine. This article explains a new way to use the latest Visual Studio for C++ development on an embedded Arm Devices from a Windows Host PC using containers for the build environment. The device we are deploying to is from the Toradex Colibri Family of System on Modules using the NXP i.MX 6ULL SoC, which features an Arm Cortex A-7. As a demo project, we will connect a Bluetooth Sensor with the Toradex Colibri Module. Please note that Visual Studio support for this case is in an early state, you will see improvements from Microsoft and Toradex in the coming months. Prerequisites Colibri i.MX 6ULL […]

Linux 4.17 Release – Main Changes, Arm & MIPS Architectures

Linus Torvalds released Linux 4.17 last Sunday: So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released. No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_distant future, and I’m told all the release scripts on kernel.org are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch […]

Qualcomm Snapdragon 850 is Designed for Windows 10 Mobile PCs

As you all probably know, Qualcomm and Microsoft worked together and launched always-on, always-connected Windows 10 mobile PCs powered by Qualcomm Snapdragon 835 Arm processor earlier this year. Battery life is spectacular, but considering the fairly high price of such devices, many were disappointed by performance which in many cases is not much better than much cheaper Intel Apollo Lake laptops. But performance of future Qualcomm based Arm laptops will improve significantly thanks to Snapdragon 850 Mobile Compute Platform featuring eight Kryo 385 cores clocked to close to 3 GHz, and other enhancements. Qualcomm Snapdragon 850 “Mobile Compute Platform” specifications: CPU – 8x Kryo 385 Arm cores clocked @ up to 2.96 GHz GPU – Adreno 630 Visual Processing Subsystem with Open GL ES 3.2, Open CL 2.0, Vulkan, DirectX 12 Ultra HD Premium video playback and encoding @ 4K (3840×2160) 30fps, Slow motion HEVC video encoding of FHD (1080p) […]

Arm Cortex M35P Armv8-M MCU Core Gets Physical Security with Anti-tampering Features

Armv8 and Armv8-M processor already support Arm TrustZone security, which aims to prevent software attacks against the target device. However, if a hacker has physical access to the hardware, it may not be sufficient to prevent hacking. Arm Cortex-M35P core addresses this issue by providing physical (hence the P in the name) security with anti-tampering features that protect against access even with direct access to the hardware. Highlights of the processor: Architecture – Armv8-M Mainline (Harvard) ISA Support – Thumb/Thumb-2 Pipeline – Three-stage Software security – Optional TrustZone for Armv8-M, stack pointers checking Physical security – Built-in protection from invasive and non-invasive attacks DSP Extensions Optional DSP/SIMD instructions Single cycle 16/32-bit MAC Single cycle dual 16-bit MAC 8/16-bit SIMD arithmetic Floating Point Unit – Optional single precision floating point unit,IEEE 754 compliant Co-processor interface – Optional dedicated co-processor bus interface for up to 8 co-processor units for custom compute Memory […]
