Samsung started to commit code related to Exynos 7 processor to mainline kernel in August, but at the time details were scarce, and many tech websites referred to a Exynos 5433 64-bit processor from Samsung. Exynos 5433 for a Cortex A53/A57 SoC did not make much sense as the company recently announced Exynos 5430 based on Cortex A15 and A7 cores, so finally Exynos 5433 has been renamed to Exynos 7 Octa. Here’s what we know about Exynos 7 Octa from information on Exynos 7 Octa page and an older Anandtech article about Exynos 5433: CPU – 4x Cortex A57 cores @ 1.9 GHz , 4x Cortex A53 cores @ 1.3 GHz GPU – Mali-T760 @ 700 MHz Memory Controller – 2x 32-bit @ 825MHz (13.2GB/s b/w) Display – Up to WQHD (2560 x 1440) / WQXGA (2560 x 1600) resolutions Video – Advanced multimedia format codec (MFC) including support […]
Samsung Gear S SmartWatch and Tizen SDK for Wearables
Albeit Tizen struggle in the smartphone market widely reported by the tech press, devices from cameras to smartwatches, all made by Samsung, are currently selling with the new mobile operating system. Announced about two weeks ago, Samsung Gear S is the latest Tizen product launched by the company. The smartwatch features a 2″ curved display (Samsung likes curved displays), Bluetooth, Wi-Fi, etc.. and it can also make phone calls and access the internet over 2G/3G cellular networks. Samsung Gear S specifications: SoC – Dual core processor @ 1.0 GHz (Maybe Exynos 3250 like in Gear 2?)

Samsung Unveils Galaxy Note 4 and Note Edge with Curved Display
IFA 2014 tradeshow is just starting today, and will last until the 9th of September, but several companies have made announcements just before the show. One of them is Samsung which announced Gear VR virtual reality kit, Tizen based Gear S smartwatch, as well as two new smarthones, Galaxy Note 4 and Note Edge, which will be the subject of this post. Samsung Galaxy Note Edge Galaxy Note Edge is much different from most other phones thanks to its curved display on one side of the phone. Other specifications: SoC – Qualcomm Snapdragon S805 quad core Krait 400 processor @ 2.7 GHz with Adreno 420 GPU System Memory – 3GB RAM Storage – 32 or 64 GB internal memory + micro SD slot (up to 64GB) Display – 5.6″ Quad HD+ Super AMOLED (2560 x 1440 + 160) Cellular Networking: 2.5G (GSM/ GPRS/ EDGE): 850 / 900 / 1800 / […]
Samsung Exynos 7 ARM Cortex A57 Processor Linux Code Submitted
Samsung has not announced any 64-bit processor yet, but according to a recent patchset Exynos 7 may be their first 64-bit ARM SoC, and it will be based on the faster Cortex A57 cores. A quick way to learn a little more is to check the device tree file (exynos7.dtsi). Here’s an interesting snippet:
1 2 3 4 5 6 7 8 9 10 |
+ cpus { + #address-cells = ; + #size-cells = ; + + cpu@0 { + device_type = "cpu"; + compatible = "arm,cortex-a57", "arm,armv8"; + reg = ; + }; + }; |
As it stands, Exynos7 would be a single core Cortex A57 processor. This sounds unlikely that a company would launch a single core processor at this stage, so it’s probably early code that may not support all cores just yet. We also know Samsung uses ESPRESSO board for development with Samsung Exynos 7 processor and 3 GB RAM. Thanks to David for the tips.

Embedded Linux Conference Europe 2014 Schedule – IoT, ARM vs x86, Optimization, Power Management, Debugging…
The Embedded Linux Conference Europe (ELC 2014), CloudOpen, and LinuxCon Europe will jointly take place at the Congress Centre Düsseldorf, in Germany on October 13 – 15, 2014. The 3-day events will consists of keynotes, presentations, and tutorials. Each day will open with two or three keynotes by speakers including Jim Zemlin (Executive Director, Linux Foundation), and Jono Bacon (XPRIZE), followed by presentation and tutorials. There will be 45 presentations for ELCE, 58 for LinuxCon, and 47 for CloudOpen, I’ll make a virtual schedule with a few sessions part of the Embedded Linux Conference Europe “track”. Monday, October 13 11:15 – 12:05 – Performance Analysis Using the Perf Suite by Mans Rullgar, Consultant When faced with a performance problem, the initial steps towards a solution include identifying the sections of code responsible and the precise reasons they are time-consuming. To this end, the ‘perf’ profiling tools provide valuable insight into the […]
Samsung Announces Exynos 5430 SoC, Manufactured with 20nm Process
Samsung already have a few octa-core big.LITTLE SoCs part of Exynos 5 Octa family with Exynos 5410, Exynos 5420, and Exynos 5422/5800, all based on 28nm process. The company has just announced a new Exynos 5 Octa processors with Exynos 5430, but this time manufactured using 20nm High-K Metal Gate (HKMG) process technology providing 25% less power consumption compared to 28nm Exynos SoCs. Exynos 5430 SoC will feature four ARM Cortex A15 cores at 1.8 GHz, four Cortex A7 cores at 1.3 GHz, supports WQHD (2560×1440) and WQXGA (2560 x 1600) displays using hibernation display and Mobile Image compression (MIC) in order to lower power consumption. It also said to support HDMI, come with a Multi Format Codec (MFC) supporting HEVC/H.265 decoding, as well as an enhanced dual ISP, and up to 17GB/s of memory bandwidth. That’s about all the information I could get at this point. The CPU core […]

Thread is a New IP-based Wireless Protocol Leveraging 6LoWPAN and 802.15.4 Standards
Wi-Fi is a neat way to connect devices to Internet, but it has two main inconveniences: relatively high cost and power consumption. Luckily there are standards that addresses the cost and power consumption issues. Radio chips based on IEEE 802.15.4, a standard which specifies the physical layer and media access control for low-rate wireless personal area networks, are common place and found in many existing devices relying on higher level wireless protocols such as ZigBee, ISA100.11a, WirelessHART, and MiWi. AFAIK, Zigbee is the most popular of the aforementioned protocols, but is hindered by the requirements of the license for commercial products (annual fee), Zigbee membership requirements conflict with many open source license such as GPL, and the standard suffers from lack of interoperability and IPv6 support, and power requirements that are too high for some applications. So a consortium of seven companies namely ARM, Big Ass Fans, Freescale, Nest, Samsung, […]
