Amazon Launches 64-bit Arm Server “A1” Instances

Amazon has developed AWS Graviton processors optimized for cloud applications and delivering power, performance, and cost optimizations over their Intel counterpart. The processors feature 64-bit Arm Neoverse cores and custom silicon designed by AWS themselves, and can be found today in Amazon EC2 A1 instances. The screenshot above shows Amazon Linux 2, Red Hat Enterprise Linux 7.6, Ubuntu 18.04 Server, and Ubuntu 16.04 Server machine images having options for either 64-bit x86 or 64-bit Arm servers. Amazon Arm server instance are particularly suitable for applications such as web servers, containerized microservices, caching fleets, distributed data stores, as well as development environments. Amazon further explains: A1 instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor, which maximizes resource efficiency for customers while still supporting familiar AWS and Amazon EC2 instance capabilities such as EBS, Networking, and AMIs. Amazon Linux 2, Red Hat Enterpise Linux […]

Forlinx OK1052-C Board Features NXP i.MX RT1052 Crossover Processor

NXP i.MX RT series crossover processors were first announced last year as processors providing the same real-time capability as found in microcontrollers while providing performance similar to entry-level application processors thanks to an Arm Cortex-M7 core clocked at up to 600 MHz. i.MX RT series also lower BoM thanks to integrated PMIC and up to 512KB SRAM/TCM. Later on uCLinux for NXP i.MX RT1050 evaluation board was released, and a few months ago, we covered the upcoming VisionSOM-RT industrial system-on-module powered by the crossover processor. That means we did not have production-ready commercial solutions so far, but this has changed recently, with for example Forlinx Embedded OK1052-C board. The solution is comprised of a baseboard and a system-on-module with the following specifications: FET1052-C SoM SoC – NXP i.MX RT1052 single core Arm Cortex-M7 crossover processor @ up to 528 MHz with 512KB SRAM/TCM System Memory – 16MB or 32MB SDRAM […]

Facebook BOLT Speeds Up Large x86 & ARM64 Binaries by up to 15%

Compilers like GCC OR LLVM normally do a good job at optimizing your code when processing your source code into assembly, and then binary format, but there’s still room for improvement – at least for larger binaries -, and Facebook has just released BOLT (Binary Optimization and Layout Tool) that has been found to reduce CPU execution time by 2 percent to 15 percent. The tool is mostly useful for binaries built from a large code base, with binary size over 10MB which are often too large to fit in instruction cache. The hardware normally spends lots of processing time getting an instruction stream from memory to the CPU, sometimes up to 30% of execution time, and BOLT optimizes placement of instructions in memory – as illustrated below – in order to address this issue also known as “instruction starvation”. BOLT works with applications built by any compiler, including the […]

An Attempt to Benchmark Entry-level x86 Boards against RK3399 & Exynos Arm Boards

Some Arm boards have become quite powerful, while hardware based on low power Intel processor has generally become cheaper with both architectures somewhat converging in terms of performance and price. Piotr Maliński got interested and purchased some low cost (<$150) Intel hardware to compare to mid-range Arm boards, throwing a Raspberry Pi 3 B+ into the mix as well for comparison. Those are the Intel test boards / computers: Qotom motherboard with Intel Atom Z3735F Bay Trail processor, 2GB RAM, 32GB flash – $74 + shipping on Aliexpress Piesia nano ITX board with Intel Celeron N2806 Bay Trail processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces – Piotr found it for around $85 on Aliexpress, but the price now jumped to over $150 plus shipping, which does not make it very attractive Generic thin mini ITX motherboard based on Celeron N3160 “Braswell” processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces. $62.68 […]

ODROID-XU4 and ODROID-XU4Q Boards Going for $49 (Promo)

ODROID-XU4, and its fanless ODROID-XU4Q sibling, are neat little single board computer packing lots of power into a small form factor. I tested ODROID-XU4 with Ubuntu 18.04 recently and was relatively impressed by how well it worked considering it’s an Arm platform, as there were still admittedly some limitations. But as they say at $59 a board you can’t beat the price. Except you can actually do, as Hardkernel is offering both ODROID-XU4Q and ODROID-XU4 for just $49 during Black Friday here and there. If you’ve already forgotten about the board it is equipped with a Samsung Exynos 5422 octa-core Cortex A15/A7 processor, 2GB RAM, eMMC module support, Gigabit Ethernet, USB 3.0, HDMI 1.4, and more. You can read the full specifications here. The only difference between ODROID-XU4 and ODROID-XU4Q is the latter comes with a large heatsink, while the former is cooled by fan. If you are currently shopping […]

Orange Pi AI Stick 2801 Neural Compute Stick SDK & Documentation Released

We covered the launch of Orange Pi AI Stick 2801 neural compute stick a few days ago, the first easily available Gyralcon Lightspeeur based USB stick, and noted that while the hardware was there, we had no details about software development kit and documentation at the time. I’ve got some more information now. First, the company release an English presentation about the neural stick, and while it’s not technical documentation, it provides insights into what it is capable of, and an overview about the workflow. More importantly, Shenzhen Xunlong Software also released Orange Pi AI Stick SDK and user manual for x86 PC, as well as cat/dog data and pre-trained models to get started. However, if you want to perform training with your own data, you’ll need to purchase the stick plus PLAI model transformation and training tools sold on Aliexpress for $218 plus shipping, that’s $69 for the hardware, […]

Diskio Pi 13.3″ DIY Tablet Kit for Raspberry Pi – Take 2 on Kickstarter

Diskio Pi was a DIY tablet kit for Raspberry Pi, ODROID-C2/XU4 and other compatible boards with a 13.3″ Full HD display that launched last year on Kickstarter. But the project failed likely due to the high costs (350 Euros and up for early bird pledges without battery nor SBC) and an elevated funding target of 400,000 Euros. But the team did not give up, worked on reducing costs, improved the design, and recently relaunched Diskio Pi on Kickstarter with a more achievable 52,096 Euros target, and reasonable pricing with rewards starting at 189 Euros including VAT. Diskio Pi “basic” DIY tablet kit content and main specifications: Display – Innolux 13.3″ TFT/IPS display with 1920×1080 resolution, WLED backlight + 10-point touch capacitive panel connected over USB 2.0 Video control board with HDMI 1.4 to eDP converter, stereo amplifier, and 2x 1W speakers Daughter board with Genesys USB hub, 9V to 5V/4A […]

ODROID-H2 Intel SBC Launched for $111

Hardkernel introduced ODROID-H2 single board computer with an Intel Celeron J4105 processor last month. The first Intel board from the company supports up to 32GB RAM via two SO-DIMM sockets, as well as M.2 NVME SSDs and SATA drives, and exposes various other ports such as HDMI 2.0 and DisplayPort video outputs, dual Gigabit Ethernet, and more. We already knew most details about the board, except for the price and exact launch date. Hardkernel launched the board today for $111 on their online store with shipments scheduled the start on November 27th. Here are ODROID-H2 specifications again with letters in parenthesis referring to the location on the photo below: SoC – Intel Celeron J4105 quad core processor @ up to 2.3 GHz (real frequency) with 12EU Intel UHD Graphics 600 (A) System Memory – Dual-channel Memory DDR4-PC19200 (2400MT/s) supporting up to 32GB RAM in total (B) Storage – M.2 PCIe […]
