Open Source Operating Systems News – Maru OS, Zephyr, ReactOS, Tizen 3.0, and Raspbian

There have been several news related to open source operating systems in the last couple of weeks including Maru OS to run Debian on Android, Zephyr Project real-time OS managed by the Linux Foundation, ReactOS an open source port of Windows XP, and Raspberry Pi boards are getting a Tizen 3.0 port, as well as a new Raspbian release. Maru OS – Mobile <-> Desktop  Convergence Maru OS mobile operating system is supposed to do what Ubuntu convergence promised: it runs in mobile mode on the go with Android Lollipop mobile OS, once you connect the phone to an HDMI screen, and pair Bluetooth keyboard and/or mouse, it will switch to desktop mode running Debian Linux. The downside is that so far it a single developer (Preetam D’Souza) worked on it, and the beta version only works on Nexus 5 smartphone. However, since the project went viral, dozen of other […]

ARM Cortex-R8 Real-Time Processor targets SSDs, LTE Advanced and 5G Modems, and Other Embedded Applications

ARM Cortex-A processor may get all the media buzz as they are found in popular consumer devices such as smartphones, but ARM also provides Cortex-R processors with real-time capabilities that are found in cars, hard drives, and other embedded systems requiring high reliability, fault tolerance, and deterministic real-time responses. The company has just announced Cortex-R8 real-time core that should double the performance of Cortex-R7 core, and targeting mainly storage devices such as SSDs and HDDs, as well as next generation LTE and 5G modems. Cortex-R8 key features: Microarchitecture – 11-stage pipeline with instruction pre-fetch, branch prediction, superscalar and out of order execution, register renaming, parallel execution paths for load-store, MAC, shift-ALU, divide and floating-point. Also features a hardware divider and is software compatible with the ARM9, ARM11, Cortex-R4, Cortex-R5 and Cortex-R7 embedded processors. Instruction Set – ARMv7-R architecture with Thumb-2 and Thumb. Support for DSP extensions, as well as an […]

Freedom251 Smartphone Sells For about $4 in India

Electronics is getting pretty cheap those days with ESP8266 WiFi modules for $2 shipped, Raspberry Pi Zero for $5 (in theory), Orange Pi One for $10, 4K TV boxes for $30 and so on. But a $4 smartphone? No way! But that’s about the price of Freedom251 smartphone  that is sold by a company called Ringing Bells for 251 Rupees, or about $3.67, plus 40 Rupees for shipping ($0.58) to India only. Freedom251 specifications: SoC – Quad core processor @ 1.3 GHz System Memory – 1 GB RAM Storage – 8 GB flash + micro SD slot up to 32GB Display – 4″ touchscreen IPS display with 960×540 resolution Connectivity – WiFi, Bluetooth, GSM and 3G Camera – 3.2MP rear camera, 0.3MP front camera Audio – 3.5mm audio jack, FM radio Sensors – Proximity sensor Battery – Removable 1,450 mAh battery The phone runs Android 5.1, and come pre-installed with […]

Samsung Introduces Exynos 7870 Octa-Core Processor for Mid-Range Smartphones

Usually the higher the model number, the faster the processor, but not with Samsung, as the company’s new Exynos 7870 processor will feature eight ARM Cortex A53 cores @ 1.6 GHz coupled with an ARM Mali-T830MP GPU. It will be manufactured with 14nm FINFET process which should reduce power consumption by 30% compared to 28nm process. The processor also include an LTE Cat.6 2CA Modem that supports 300Mbps downlink speed and FDD-TDD joint carrier aggregation. Multimedia capabilities include 1080p 60fps video playback, 1920×1200 display resolution, and 16MP front or camera support (8MP in dual camera configuration) via its image signal processor (ISP). Exynos 7870 processor will also integrate a GNSS solution that delivers fast time-to-first-fix (TTFF) feature. In the recent pas, low and mid-range SoC were usually manufacturer with 28nm process due to the high cost of 14nm process, but those costs must have come down dramatically, after Snapdragon 625 […]

Meizu PRO 5 Ubuntu Edition Smartphone is Powered by Exynos 7420 Processor, Does NOT Support Desktop Mode Yet

So far most smartphones with alternative operating systems had rather low-end to mid-end hardware specifications, but according to OMG! Ubuntu!, Canonical and Meizu are about to change that, as they should be about to launch an Ubuntu Edition of Meizu PRO 5 smartphone with an Exynos 7420 octa-core Cortex A57/A53 processor coupled with 3 to 4GB RAM, 32 to 64GB storage., and a 5.7″ display with 1920×1080 resolution. The device will support convergence, meaning it could work in mobile or desktop mode, just like the recently announced BQ Aquaris M10 tablet. [Update: Finally, the USB-C port on Meizu PRO 5 does not support external display, so no convergence, unless Canonical decides to implement convergence over Miracast…]. Meizu PRO 5 Ubuntu Edition specifications: SoC – Samsung Exynos 7 Octa (Exynos 7420) octa core processor with 4x Cortex A57 core @ 2.1GHz + 4x Cortex A53 cores @ 1.5Ghz, and Mali-T760 MP8 GPU […]

Voyo V3 Intel Atom x7-Z8700 mini PC Review with Windows 10

Voyo V3 is one of the first Cherry Trail mini PCs based on Intel Atom x7-Z8700 quad processor that promises both higher CPU and GPU performance, and more I/O connectivity compared to Intel Atom x5 platforms.  I’ve already posted pictures of the device and its guts in the first part of the review,  so today in part 2 of the review, I’ll focus on testing how the device perform with its pre-installed operating system: Windows 10 Home. Setup and System Information There’s no much to say about setup for this device, since all you have to do is to connect the cable, and press the button to access Windows 10 desktop. There are however two interesting aspect of the boot process: As you connect the power supply, you’ll see the power button blue LED lit, but it does not mean it has started. I could see the power consumption was […]

NexDock is a 14″ Lapdock Alternative for mini PCs, Development Boards, Smartphones and Tablets (Crowdfunding)

Motorola once launched the Lapdock, a device that looks like a laptop with a 11.6″ screen and a keyboard, but without processor or memory since it was instead designed to connect to the company’s Atrix 4G smartphone. Motorola eventually pulled the plug on this concept, and maybe it was just ahead of its time, as a startup has now developed NexDock, a device similar to Lapdock with a 14″ display, built-in battery and Bluetooth keyboard. NexDock technical specifications: Display – 14.1″ TN screen; 1366×768 resolution; 16:9 display ratio Bluetooth 4.0 keyboard and touchpad Video input – mini HDMI port Audio Output – 3.5mm headphone port Storage – micro SD card slot USB – 2x USB ports Battery – 3.8V / 10000mAh Li-ion battery Power – 5V/2.5A via 3.5mm power barrel Dimensions – 351 mm x 233 mm x 20 mm Weight – 1490 grams NexDock is operating system agnostic and would […]
