Marvell Introduces ARMADA PXA1936 & PXA1908 Octa & Quad Core Cortex A53 LTE SoCs for Smartphones and Tablets

November 18th, 2014 No comments

Marvell announced ARMADA PXA1928 quad core Cortex A53 LTE SoC at the beginning of the year, and they’ve now introduced two new Cortex A53 based processors with PXA1936 and PXA1908, featuring respectively eight and four ARM Cortex A53 cores at 1.5 GHz, and 5-mode 4G LTE support (TD-LTE, FDD-LTE, TD-SCDMA, WCDMA and GSM). PXA1936 targets high performance smartphones and tablets, whereas PXA1908 targets mid-range / mainstream mobile devices.

PXA1936

Key features of the Marvell ARMADA Mobile PXA1936 include:

  • Octa core Cortex A53 up to 1.5GHz
  • Supports 1080p display, and video encoding and decoding
  • Improved image processor to support 13 to 16MP camera
  • Advanced power management and audio codec for power efficiency and audio performance
  • Enhanced security processor
  • Integrated location and sensor hub functionalities for better usability
  • Field proven DSDS (Dual Sim Dual Standby) software for 5-mode modem

While key features of Marvell ARMADA Mobile PXA1908 include:

  • Cost optimized quad-core Cortex A53 up to 1.2GHz
  • Improved image processing to support 8MP to 13MP camera
  • Advanced power management
  • Supports 720p display
  • DSDS software for 5-mode modem

There’s no mention of the GPU, but the previously announced PXA1928 integrates a Vivante GC5000 GPU, so it might be these two new processors also come with a Vivante GPU. Both processor will support Android L. The only difference between PXA1908 and PXA1928 quad core processor is support for “mobile security features, including secure boot, root key protection and Widevine Level 1 support and FIPS 104-2 Level 3- and 140-3 Level 2-compliant” for the latter.

Marvell expects both processor to be found in smartphones and tablets in early 2015. A few more details may be found on PXA1908 and PXA1936 product pages.

Thanks to embedded_geek for the tip.

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

October 31st, 2014 No comments

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 carried over FVP Base and Foundation models, and Juno support from the integration-linaro-vexpress.
    • updated LLVM topic (uses llvmlinux-2014.10.01 branch – the most recent v3.17-based version of llvmlinux-latest)
    • dropped ARMv7 big endian topic(obsoleted; most of the patches are upstream)
    • added ILP32 patch set v3 with one minor build fix. (ILP32 vs LP64 data models)
    • config fragments changes – distribution.conf: CONFIG_IPV6=y replaced with CONFIG_IPV6=m
  • Linux Linaro LSK 2014.10:
    • The v3.14 based LSK based on kernel.org 3.14.19 stable tree
    • Updates to:
      • kernel.org 3.10.55 stable tree
      • Android support (from Google and Linaro)
      • ARMv8 fixes and performance enhancements
      • UEFI support
      • Mailbox framework
  • Linaro Toolchain Binaries 2014.10
    • based on GCC 4.9 and updated to latest Linaro TCWG releases (Linaro GCC 4.9-2014.10)
    • first release built with cbuild2, adding more maintainable code base and automatic testing
    • binary tarballs have been splitted into 3 parts. As a result, you can install only the parts needed:
      • gcc-linaro-*.tar.xz – the compiler and tools
      • runtime-linaro-*.tar.xz – runtime libraries needed on the target
      • sysroot-linaro-*.tar.xz – sysroot (a set of libraries and headers to develop against)
  • Linaro builds of AOSP 14.10
    • built with Linaro GCC 4.9-2014.10
    • AOSP master build for Juno is cleaned up. It now builds without any patches on AOSP projects. It builds by adding 9 projects to AOSP manifest related to device, kernel, toolchain and helper tools.
    • LSK Android testing issues are fixed for ARMv8 Fast Models
    • bc tool is added to ARMv8 Android Juno build
  • Linaro OpenEmbedded 2014.10
    • integrated Linaro GCC 4.9-2014.10
    • fixed shadow securetty for SBSA compatible UART
    • switched OpenJDK to upstream aarch64 hg repos
    • dropped mongodb from LAMP images
    • upstreaming:
      • updated acpica 20140828 release
      • updated acpitests 20140828 release
      • updated pm-qa to 0.4.14 release
      • added aarch64 support to libunwind
      • fixed PHP build warnings
  • Linaro Ubuntu 14.10 – Updated packages: Juno firmware 0.8.2, LSK 3.10.58/3.14.22 and linux-linaro 3.17 kernels, xf86-video-freedreno 1.3.0
  • Debian arm64 support is going very well. More than 90% of the packages are built. The effort is on track to get next Debian release with an officially supported arm64 architecture.
  • KVM CI loop on Juno is completed. The remaining work is happening on Xen CI loop.

You can visit https://wiki.linaro.org/Cycles/1410/Release for a list of known issues, and further release details about the LEB, LMB (Linaro Member Builds), and community builds, as well as Android, Kernel, Graphics, Multimedia, Landing Team, Platform, Power management and Toolchain components.

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

October 26th, 2014 5 comments

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.

HEP_Test_Systems_X-Gene_Intel_Xeon
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 Fedora 19, whereas the Intel processor used Scientific Linux CERN 6.5.

The researchers run the CERN’s CMSSW applications for testing. Let’s jump to the results.

AOM_X-Gene_1_vs_Intel_XeonAs expected Intel Xeon processor and Phi coprocessor both have more performance than X-Gene 1 ARM SoC.

X-Gene_Intel_Xeon_Phi_Performance_Per_WattHowever, when it comes to performance-per-watt, APM X-Gene 1 is clearly ahead of Intel Xeon E5-2650 and there’s no comparison against Xeon Phi systems.

The conclusion of the report reads as follows:

We have built the software used by the CMS experiment at CERN, as well as portions of the OSG software stack, for ARMv8 64-bit. It has been made available in the official CMS software package repository and via the CVMFS distributed file system used by Grid sites.

Our initial validation has demonstrated that APM X-Gene 1 Server-on-Chip ARMv8 64-bit solution is a relevant and potentially interesting platform for heterogeneous high-density computing. In the absence of platform specific optimizations in the ARMv8 64-bit GCC compiler used, APM X-Gene 1 shows excellent promise that the APM X-Gene hardware will be a valid competitor to Intel Xeon in term of power efficiency as the software evolves. However, Intel Xeon Phi is a completely different category of product. As APM X-Gene 2 is being sampled right now, built on the TMSC 28nm process, we look forward to extending our work to include it into our comparison.

You can read the full report “Heterogeneous High Throughput Scientific Computing with APM X-Gene and Intel Xeon Phi” for details.

Samsung Officially Announces Exynos 7 Octa big.LITTLE ARM Cortex A53/A57 Processor

October 16th, 2014 7 comments

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.

Exynos_7_OctaHere’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 for H.265/HEVC @ 60 fps
  • Camera – Up to 16 MP 30fps rear camera, Up to 5MP / 30 fps front-facing camera, with dual ISP allowing for simultaneous video recording.
  • Process – 20 nm HKMG

A57 cores are said to provide 57% more performance than the A15 cores found in Exynos 5 Octa processors, whereas. Mali-T760 GPU should deliver up to 74% enhanced graphics performance over Mali-T628 used in Exynos 5 Octa.

Samsung Exynos 7 is used in the international version of the Galaxy Note 4 smartphone.

Rockchip RK3126, RK3128, and “MayBach” Octo-core Cortex A53 Processor Could Be Found in Tablets in Q4 2014

September 24th, 2014 4 comments

T-chip, the company behind Firefly-RK3288 development board and HPH NT-V6 media player, has sent me their latest company brochure this morning. The brochure mentions the company history since 2005, various tablets solutions they have done over the year, and new and upcoming products. One of the slides particularly caught my attention.

Rockchip_RK3128_RK3126_MayBachRK3288 is pretty popular right now, but I had never heard about RK3126 and RK3128 SoC with four ARM Cortex A7 core with a Mali GPU supporting HEVC decoding up to 1080p resolution. Both processors are manufactured using 40nm technology, so I’d guess these target ultra low cost tablets, which should become available in October and November 2014.

Even more interesting is the mention of “MayBach” Tablets. I’ve been told MayBach, which could just be a temporary codename, is an upcoming Rockchip SoC. Based on the information in the slide, it should be an Octa-core Cortex A53 processor with an unnamed GPU supporting OpenGL ES 3.0. Supported features include 4K/H.265 video decoding, HDMI 2.0 / LVDS / DSI / eDP video outputs, and an ISP with CSI2 camera interface(s).

I could not find more information about a Rockchip Cortex A53 on the web, except that Rockchip licensed Cortex A50 cores in November 2013.

Separately, I’ve also asked T-Chip about Firefly-RK3288 availability, and that’s what I’ve been told:

Firefly demoboard won’t purchase online on foreign website and the time when it will purchase online inland is not determined.

Disappointing. This conflicts with new that the board would be listed on Taobao next week. so if you want the board, you may have to order by email ($129 + shipping), as mentioned by Charbax, or simply wait for Radxa Rock 2 instead.
