Hardkernel Now Offers $48 ODROID-MC1 Solo Board for Clusters

Hardkernel launched ODROID-MC1 (My Cluster One) at the end of last year with four ODROID-XU4S boards powered by Samsung Exynos 5422 processor with Gigabit Ethernet, metal cases, and a cooling fan. As the name implies it is designed for cluster of boards, but the company found out that one size (4 boards) does not fit all, so they are now offered ODROID-MC1 Solo with one ODROID-XU4S board and stackable case to provide more flexibility to their customers. Here’s a reminder of the specifications: SoC – Samsung Exynos 5422 quad core ARM Cortex-A15 @ 2.0GHz quad core ARM Cortex-A7 @ 1.4GHz with Mali-T628 MP6 GPU supporting OpenGL ES 3.0 / 2.0 / 1.1 and OpenCL 1.1 Full profile System Memory – 2GB LPDDR3 RAM PoP Storage – 1x micro SD slot (UHS-1 capable) Network Connectivity – 10/100/1000Mbps Ethernet (via Realtek RTL8153 USB 3.0 to Ethernet bridge) USB – 1x USB 2.0 […]

Microsoft Introduces Azure Sphere OS Linux Operating System for Certified Microcontrollers (MediaTek MT3620 for now)

Last year, Microsoft announced they were working with Mediatek on Project Sopris Secure WiFi MCU, based on Mediatek MT7687 MIPS microcontroller with 7 properties enhancing security (Hardware-based Root of Trust, failure reporting etc…). The company has now unveiled a complete secure IoT solution with Azure Sphere comprised of three main components: Azure Sphere certified secured MCUs which combine real-time and application cores with built-in Microsoft security technology and connectivity. The first compatible MCU will be Mediatek MT3620, which differs from MIPS based Project Sopris, as it features one Cortex A7 and two Cortex M4 cores as well as WiFi connectivity. Azure Sphere OS that provides four layers on top of the hardware: security monitor, custom Linux kernel, on-chip connectivity services to Azure Sphere Security Service, and app containers for computer (A7 core) or/and real-time I/Os (M4 cores). Azure Sphere Security Service, a secure cloud service for Azure Sphere device that […]

Hikey 970 Development Board is Now Up for Pre-order for $299.99

Four A.I. development boards compliant with 96Boards specifications were announced at Linaro Connect HK 2018 last month: HiKey 970, Ultra96, as well as ROCK960 PRO & Enterprise Edition. So for we only knew pricing for Ultra96 ($249), but I’ve now noticed Hikey 970 “Super Edge AI Computing Platform” is now up for pre-order for $299.99 on Lenovator website, with shipping planned for the end of April. [Update: Also found on Seeed Studio for the same price] Hikey 970 specifications: SoC – Huawei/Hisilicon Kirin 970 with 4x Cortex A73 @ 2.36GHz, 4x Cortex A53 @ 1.8GHz, Arm Mali G72-MP12 GPU, NPU (Neural Processing Unit) with 256MAC/cycle @ 960MHz System Memory – 6GB 1866MHz, 4 Channel LPDDR4x Storage – 64GB UFS storage, micro SD card slot, PCIe Gen3 on M.2 M key connector Video Output – HDMI 1.4 type A up to 1080p60 (TBC), 1x 4-lane MIPI DSI (via HS expansion connector) […]

How to Install and Use Ace Stream Easily in Ubuntu / Mint Linux

Ace Stream enabling the streaming of videos using P2P (peer-to-peer) technology – specifically BitTorrent protocol – and is especially useful for live streams, but also works for Audio and Video on Demand, and IOTT (Interactive-Over-The-Top). Ace Stream is implemented in a fork of VLC (Ace Player HD) working in Windows, Linux and Android, and I’ve found Full HD quality to be higher than services like YouTube, and with less buffering provided enough users watches the stream. It’s easy to use in Windows, and there used to be an Android app installable from the Play Store but it’s been removed, possibly because of the association of the solution with piracy. But just like Kodi, it’s up to do what you want to use it for. Using Ace Player was easy in Ubuntu up to version 14.04 thanks to a ppa, but with Ubuntu 16.04 it become a little more complicated as you […]

Optimizing JPEG Transformations on Qualcomm Centriq Arm Servers with NEON Instructions

Arm servers are already deployed in some datacenters, but they are pretty new compared to their Intel counterparts, so at this stage software may not always be optimized as well on Arm as on Intel. Vlad Krasnow working for Cloudflare found one of those unoptimized cases when testing out Jpegtran – a utility performing lossless transformation of JPEG files – on one of their Xeon Silver 4116 Server:

vlad@xeon:~$ time  ./jpegtran -outfile /dev/null -progressive -optimise -copy none test.jpg

real    0m2.305s
user    0m2.059s
sys     0m0.252s

vlad@xeon:~$ time ./jpegtran -outfile /dev/null -progressive -optimise -copy none test.jpg

real 0m2.305s

user 0m2.059s

sys 0m0.252s

and comparing it to one based on Qualcomm Centriq 2400 Arm SoC:

vlad@arm:~$ time ./jpegtran -outfile /dev/null -progressive -optimise -copy none test.jpg

real    0m8.654s
user    0m8.433s
sys     0m0.225s

vlad@arm:~$ time ./jpegtran -outfile /dev/null -progressive -optimise -copy none test.jpg

real 0m8.654s

user 0m8.433s

sys 0m0.225s

Nearly four times slower on a single core. Not so good, as the company aims for at least 50% of the performance since the Arm processor has double the number of cores. Vlad did some optimization on The Intel processor using SSE instructions before, so he decided to look into optimization the Arm code with NEON instructions instead. First step was to check which functions may slowdown the […]
