Qualcomm Unveils Snapdragon 650 and 652 ARM Cortex A72 / A53 Processors

[Update: Title updated to reflect the new names of the processors. Snapdragon 618 is now Snapdragon 650, and 620 is now 652 to reflect the better Cortex A72 cores used in those processors] Qualcomm has announced four new processors including Snapdragon 415 and 425 octa-core Cortex A53 processor, as well a Snapdragon 618 and 620 big.LITTLE processor with the latest Cortex A72 cores coupled with four Cortex A53 little cores. Snapdragon 618 is the hexa-core version with 2 Cortex A72 cores, while Snapdragon 620 comes with eight cores including 4 Cortex A72, but apart from the difference in number of cores, both share the same technical specifications: CPU Snapdragon 618 – 64-bit dual-core ARM Cortex A72 @ 1.8GHz and quad-core Cortex A53 @ 1.2GHz Snapdragon 620 – 64-bit quad-core ARM Cortex A72 @ 1.8GHz and quad-core Cortex A53 @ 1.2GHz GPU – Next generation Qualcomm Adreno GPU with support for […]

Linux 3.19 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 3.19 yesterday: So nothing all that exciting happened, and while I was tempted a couple of times to do an rc8, there really wasn’t any reason for it. Just as an example, Sasha Levin used KASan and found an interesting bug in paravirtualized spinlocks, but realistically it’s been around forever, and it’s not even clear that it can really ever trigger in practice. We’ll get it fixed, and mark it for stable, and tempting as it was, it wasn’t really a reason to delay 3.19. And the actual fixes that went in (see appended shortlog) were all fairly small, with the exception of some medium-sized infiniband changes that were all reverting code that just wasn’t ready. So it’s out there – go and get it. And as a result, the merge window for 3.20 is obviously also now open. Linus Linux 3.18 improved performance of […]

Embedded Linux Conference 2015 Schedule – IoT, Cars, and Drones

Embedded Linux Conference 2015 will take place in San Jose, California, on March 23 – 25, 2015, and will focus on Drones, Things and Automobiles. The schedule has been published, and whether you’ll attend or not, it’s always interested to have a look at what will be talked about to have a peak into the future of Embedded Linux, or simply keep abreast with the progress in the field. So as usual, I’ve gone through the schedule, and made my own virtual program with talks that I find interesting. Monday 23rd 9:00 – 9:30 – Driving standards and Open Source to Grow the Internet of Things by Mark Skarpness, Director of Systems Engineering at Intel Billions of devices are beginning to come online, and many of these devices, large and small, are running open source software. To fuel this innovation, it’s more important than ever for these devices to use […]

Online Labs pBox (C1 Node) is a mini ARM Server with 4 Gigabit Ethernet Ports, mSATA and mPCIe Slots

Online Labs, a subsidiary of Iliad (free), recently launched hosting services with dedicated ARM servers based on Marvell processor with modules they call C1. The company has decided to design a baseboard (pBox) for C1 module, and, as I understand it, plans to sell it to the public. It’s an exciting development for those who are looking for affordable and tiny purpose built Linux ARM servers. Preliminary C1 Node / pBox mini server specifications (based on C1 specs and bits of information gathered online): SoC – Marvell Armada 370/XP quad core ARMv7 processor @ up to 1.2 GHz System Memory – 2GB RAM Storage – 256 MB NAND flash + mSATA slot + eSATA port + micro SD slot Connectivity – 4x Gigabit Ethernet ports USB – 1x micro USB port Expansion – mini PCie, 1x 20-pin header for expansion (no details yet) Debugging – 20-pin JTAG connector Power Supply […]

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

Linux Benchmarks – Rockchip RK3288 vs Exynos 5422 vs AllWinner A80 vs Intel Atom Z3735F

With all these Intel Atom Z3735F been released right now at a price similar to ARM based mini PCs, many people, including myself, are wondering about the performance of the low cost Intel processor against their ARM competitors. Ian Morrison just published some results from Phoronix Test Suite comparing the performance of Firefly-RK3288 (Rockchip RK3288), ODROID-XU3 Lite (Samsung Exynos 5422 BIN2), and A80 OptimusBoard (Allwinner A80) in Linux (Ununtu 12.04.5), against the performance of MeegoPad T01 (Intel Atom Z3735F) running Linux from a Live CD on a USB drive. Some of the benchmarks failed because Phoronix Test Suite got apparently confused with the file systems located on a USB drive, but at least we’ve got a comparison point, and the results are a bit confusing, as they’re no clear winner. In some tests like FFmpeg, the Intel SoC really crushed the ARM competition being at least twice as fast as […]
