Qualcomm Showcases 4K LTE HDMI TV Streaming Dongle

October 21st, 2014 5 comments

There are now many wireless display adapters supporting Miracast, EZCast, DLNA, Airplay…, and streaming videos from your smartphone to the TV over Wi-Fi in 720p or 1080p resolution. Qualcomm recently unveiled a prototype called “4K Stream Adapter (4SA)” that does about the same but instead support 4K UHD resolution, and allegedly supports LTE thanks to its Qualcomm Snapdragon 800+ processor.

According to a PCWorld report, Qualcomm mainly expects the device to be used to stream 4K video captured with a phone to a 4k UHD television, but it might also ending up supporting online video services such as Netflix, and mirroring your mobile device’s display onto the big screen. It’s also said to use a “basic Universal Plug and Play protocol” to connect with other devices, and the company is working to support communication with media apps such as BubbleUPnP, VLC and MXPlayer. Currently 4SA is only a prototype to demonstrate its capabilities to hardware OEM/ODM and software companies.

SemiAccurate also mentions the device supports LTE, and while it’s unlikely consumer ever use LTE to stream 4K video at home, it could be used in location where other network connectivity are not available, for example for digital signage players in remote locations. The player would probably download content over LTE, store it in a large enough flash, and play the content for a while, instead of simply continuously streaming content due to cost considerations.

Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

September 27th, 2014 No comments

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4.

Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month.

Here are the highlights of this release:

  • Linux Linaro 3.17-rc4-2014.09
    • GATOR version 5.19
    • updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT
    • updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT.
    • updated Versatile Express patches from ARM LT
    • updated LLVM topic (follows the community llvmlinux-latest branch)
    • Big endian support (the 2014.05 topic version rebased to 3.17 kernel)
    • config fragments changes – added gcov config fragment, disabled DRM_EXYNOS_IOMMU to work around boot failure on Arndale
  • Linaro Toolchain Binaries 2014.09
    • based on GCC 4.9 and updated to latest Linaro TCWG releases: Linaro GCC 4.9-2014.09, Linaro binutils 2.24-2014.09, and Linaro GDB 7.8-2014.09.
    • This will be the last release done with cbuild1 and crosstool-ng. Next releases will be done with cbuild2. Official support for very old host environments will be dropped.
  • Linaro builds of AOSP 14.09 built with Linaro GCC 4.9-2014.09.
  • Linaro OpenEmbedded 2014.09
    • integrated Linaro GCC 4.9-2014.09, Linaro binutils 2.24-2014.09, integrated Linaro GDB 7.8-2014.09.
    • imported Linaro eglibc 2.19 into meta-linaro after OE-core switched to glibc 2.20
    • fixed shadow securetty for Qualcomm and STMicroelectronics SoCs
    • upstreaming – fixed libpng on aarch64 (neon symbol), updated PM QA to 0.4.14, updated libunwind to include aarch64 support
  • Linaro Ubuntu 14.09
    • added linux-tools (perf standalone, splitted from kernel build)
    • updated packages: Juno firmware 0.8.1, LSK 3.10.55/3.14.19 and linux-linaro 3.17-rc4 kernels.
  • A gcov enabled build has been added
  • Linaro builds of the Android NDK have been updated to current upstream sources and current Linaro toolchain component releases.
  • Standalone Android toolchain binary builds now use Linaro binutils for improved armv8 support.

ARM and Qualcomm Release a New Guide About 32-bit to 64-bit SoCs

July 30th, 2014 1 comment

ARM and Qualcomm have been pretty successful with ARMv7 SoCs in the mobile space in recent years, and while 32-bit ARM (Aarch32) processors certainly have a few more years, both companies are now moving to 64-bit ARM (Aarch64 / ARMv8), and they released a document showing what has been achieved with ARMv7, the differences between ARMv7 and ARMv8, and new capabilities that will be attainable with 64-bit processing.

Aarch32 vs Aarch64

Aarch32 vs Aarch64

The document covers the following:

ARM vs x86 vs Architecture Indepent Code for 100 Top Apps in Google Play (US)

ARM vs x86 vs Architecture Independent Code for 100 Top Apps in Google Play (US)

  • Introduction
  • ARM Business Model
  • The Mobile Computing Revolution (Tablets replacing Laptops)
  • Android on ARMv7-A and ARMv8-A
  • ARMv8-A Architecture
  • Backward Compatibility to ARMv7-A
  • ARM Cortex A-53 and Cortex-A57
  • ARM big.LITTLE Technology

Intel Atom Z3580 MooreField SoC Shown to Outperform Qualcomm Snapdragon 801 in Graphics Benchmark

June 6th, 2014 1 comment

This is not exactly an independent benchmark, as Intel provided the results showing an Intel Atom Z3580 SoC with PowerVR G6430  @ 533 MHz outperform a Snapdragon 801 with Adreno 330 GPU @ 578 MHz (Galaxy S5) in FutureMark’s 3DMark benchmark by 20997 to 18144, or a little over 15%.  We’ve seen several CPU benchmarks before where Intel often has a edge over ARM based solution, but the previous generation with Intel Graphics was a bit weak on the graphics side, and this test seems to confirm, the new Intel smartphone SoC should provide very good graphics performance.

Intel_MooreField_Snapdragon_801

It appears Atom Z3580 might have also outperformed Snapdragon 805 with Adreno 420, as Anandtech reported an overall score of 19,698 in 3Dmarks with Qualcomm Snpadragon S805 mobile development platform (MDP), and noticed it was not the most GPU intensive test there is. So it’s still possible the higher score found on Intel’s smartphone reference design may be highly CPU bound, and more graphics benchmark are needed to really get a grasp on the upcoming Intel Moorefield 3D graphics performance.

Part of the setup at Intel’s booth at Computer 2014, was also an Intel Z3480 SoC (Merrifield) with a PowerVR G6400 GPU @ 533 MHz getting 16,407 points in the same benchmark.

Actual products based on Intel Merrifield and Moorefild SoC are expected to start shipping later this month. You can find more details and benchmarks results, released by Intel, for CPU and GPU on an earlier post about Intel Atom Z3460 & Z3480 (Merrifield) and Z3560 & Z3580 (Moorefield) Mobile SoCs.

Meetion MT-WF910 Wi-Fi Player Streams Audio from your Mobile Device to your Hi-Fi System

June 2nd, 2014 4 comments

There are several ways to play music wirelessly from your devices on decent speakers. One the best way might be one of the Sonos Wi-Fi speakers, but they costs a few hundred dollars. You could also use a ChromeCast or EZCast / Miracast / DLNA dongle, both of which are very cheap ($20 to $35), and would allow you to stream music to your TV from your Android or iOS mobile device, Windows PC or Mac OS computers, but these require you leave your TV on, unless you use a DLNA dongle with an AV port. Another option would be to use a dedicated Wi-Fi player such as Meetion MT-WF910 which can receive audio from mobile devices or computers via Wi-Fi, and output it to a 3.5 mm stereo jack or S/PDIF port.
Meetion_WiFi_Player Meetion Wi-Fi player specifications and key features:

  • SoC – Qualcomm Atheros AR9331 processor for Wi-Fi and audio processing
  • System Memory – 32MB DDR2
  • Storage – 8MB Internal Flash + micro SD card
  • Audio Output – 3.5mm stereo jack, optical S/PDIF
  • Connectivity – 802.11b/g/n standard (Max 150Mbps) with WPA/WPA2 encryption
  • Wireless Standards – DLNA and Airplay
  • USB – 1x USB port for mass storage or 3G dongle, 1x micro USB for power
  • Misc – Power and Wi-Fi LEDs, reset button
  • Power – 5V DC, 0.5 to 2.1A
  • Dimensions – 85mm x 85mm x 24.7mm.
  • Weight – 40 grams

Devices running iOS such as iPhone, iPad, and iPod touch, you simply stream audio using Airplay, but Android devices require WiFiPlayer app from Meetion, although I’d assume other DLNA apps might just work. To stream audio files using a Mac or PC, simply install iTunes, and select “WiFiPlayer” as external equipment. You can connect to the device either via Wi-Fi Direct or through your home’s Wi-Fi router, and both local and online music are supported. The device can also play music directly from a micro SD card or a USB flash drive.

Charbax interviewed the company, and they showcased their device in the video below.

Meetion sells the device for $15 in quantities (1K), but the retail price including shipping is close to $40 on Aliexpress [Update: $35 here]. You can find instructions explaining how to use the device on the Aliexpress link, or visit Meetion MT-WF910 for more details.

Thanks to Oliveira for the tip. Via armdevices.net.

[Update: More technical details are available on OpenWRT forums]
