Rockchip Introduces RK3368 Octa Core Cortex A53 SoC for Tablets and 4K TV Box

Rockchip is also at CES 2015, and they’ve announced and are showcasing a new octa-core processor called RK3368 with eight 64-bit ARM Cortex A53 cores that will go into tablets and 4K UHD media players in the coming year. Most news outlet and blogs at CES only cover big brand, so all I got are a few tweets from Rockchip twitter account. The eight cores will be clocked up to 1.5 GHz, and the SoC includes an unnamed GPU with support for OpenGL ES 3.1, OpneCL 1.2 and DirectX 9.3. 4Kx2K H.265 and H.264 video decoding will be handled by the chip too, as will out HDMI 2.0 for up to 2160p @ 60 Hz video output. RK3368 tablets and media players will run Android 5.0 Lollipop. RK3368 is probably the official name for MayBach processor. I’m now fully relying on Charbax to get more details about Rockchip new processor… […]

How to Install Ubuntu ARM64 on Nexus 9 Tablet

HTC Nexus 9 is one of the first 64-bit ARM platform with powerful ARMv8 cores (e.g. not Cortex A53) that both commercially available, and relatively affordable at $399 to $599, at least significantly cheaper than the server boards such as Applied Micro X-C1. The tablet comes with Android 5.0 Lollipop, but for those of you who wish to have an ARM64 platform running Ubuntu or other 64-bit Linux operating systems, Ubuntu installation instructions provided by Ryan Houdek, Dolphin emulator developer, might come handy, especially it won’t affect your Android installation provided you have already unlocked your bootloader. The instructions are fairly long so I won’t reproduce them all here, so I recommend you check the detailed instructions on XDA, but the short summary below may give an idea of the amount of work needed: Install dependencies such as Aarch64 toolchain:

sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

1	sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

Build a initramfs with buildroot. You’ll need to enable […]

Linaro 14.12 Release with Linux 3.18 and Android 5.0

Linaro usually releases images and source code on the last Thursday of the month, but since most people will have long holidays for Chritsmas and New Year, the last working Thrusday of this month was yesterday (18th). Linaro 14.12 release includes Linux kernel 3.18 (baseline), Linux 3.10.62 & 3.14.26 (LSK, same versions as last month), and Android 5.0.1 Lollipop. Here are the highlights of this release: Linux Linaro 3.18-2014.12 Based on v3.18 release GATOR topic: version 5.20 updated topic from Qualcomm LT (includes IFC6410 board support) updated integration-linaro-vexpress64 topic by ARM LT (FVP Base and Foundation models, and Juno support) updated LLVM topic (uses the community llvmlinux-latest branch) included ILP32 patch set v3 rebased on 3.18. Boot tested with aarch64 userland. Work is in progress to test with aarch64-ilp32 userland. config fragments updated – SELinux related config options enabled in linaro-base.conf, device tree runtime self tests enabled in distribution.conf Linaro […]

Sony Xperia Z4 Tablet Ultra Could Feature a 12.9″ Display, a 64-Bit ARM Processor, 6 GB RAM, and More

That’s only a leak, but if true, the upcoming Sony Xperia Tablet Ultra would be a real beast with a 12.9″ IPS TRILIMINOS touchscreen display with 3840 x 2400 resolution, a Qualcomm Snapdragon 810 64-bit Octa core processor @ 2.86 GHz coupled with 6GB LPDDR4 RAM, and 64GB internal storage. Sony’s tablet ould also come with an HDMI 1.4 input port allowing 4K recording up to 30 fps, which looks like an odd feature for a tablet. The battery capacity would be rather large as well as 12,100 mAh, yet thickness only 8.6 mm, which might be possible due to the massive screen. It would most probably run Android 5.0 Lollipop.

Linaro 14.10 Release with Kernel 3.17 and Android 4.4.4, Debian ARM64 Port Almost Complete

Linaro 14.10 has just been released with Linux kernel 3.17 (baseline), Linux 3.10.54 & 3.14.19 (LSK, same versions as last month), and Android 4.4.2 & 4.4.4. Most of the work is a continuation of previous months working member hardware, and ARM64, but one particularly interesting point is that 90% of Debian packages have been built for ARM64, and the next version of Debian should have an official ARM64 port. Here are the highlights of this release: Linux Linaro 3.17-2014.10 updated linaro-android topic. In particular, CONFIG_IPV6=y is no longer the requirement for linux-linaro tree builds GATOR version 5.19 (same version as in 2014.08 release). gatord is fixed to build for ARMv8. dropped multi_pmu_v2 topic by ARM LT (no longer used) updated topic from Qualcomm LT (include IFC6410 board support) replaced integration-linaro-vexpress topic by integration-linaro-vexpress64. Starting from 2014.10 release, linux-linaro kernel tree will use the mainline support for 32-bit vexpress boards. integration-linaro-vexpress64 […]

Applied Micro X-Gene (64-bit ARM) vs Intel Xeon (64-bit x86) Performance and Power Usage

A group of researcher at CERN have evaluated Applied Micro X-Gene 1 64-bit ARM XC-1 development board against Intel Xeon E5-2650 and Xeon Phi SE10/7120 systems, and one of them, David Abdurachmanov, presented their findings at ACAT’ 14 conference (Advanced Computing and Analysis Techniques) by listing some of the issues they had to port their software to 64-bit ARM, and performance efficiency of the three systems for data processing of High Energy Physics (HEP) experiments like those at the Large Hadron Collider (LHC), where performance-per-watt is important, as computing systems may scale to several hundred thousands cores. Intel Xeon Phi platform based on Many Integrated Cores (MIC) computer architecture was launched the HPC market, and contrary to the table above features 61 physical cores. Applied X-Gene 1 (40nm process) was used instead of X-Gene 2 built on 28-nm process which was not available at the time. The ARM platform ran […]
