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

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]

May 28th, 2014 5 comments

prplIn what looks like an answer, albeit fairly late, to Linaro, the non-profit organization working on open source software for ARM based SoCs, a consortium of companies composed of Imagination Technologies, Broadcom, Cavium, Lantiq, Qualcomm, Ingenic, and a few others, has funded Prpl (pronounced Purple), “an open-source, community-driven, collaborative, non-profit foundation targeting and supporting the MIPS architecture—and open to others—with a focus on enabling next-generation datacenter-to-device portable software and virtualized architectures”.

The Prpl foundation will focus on three key objectives:

  • Portability – To create ISA agnostic software for rapid deployment across multiple architecture
  • Virtualization & security – To enable multi-tenant, secure, software, environments in datacenter, networking & storage, home, mobile and embedded
  • Heterogeneous Computing – To leverage compute resources enabling next generation big data analytics and mining

Initially there will PEG (Prpl Engineering Group) to take of the following projects for 4 market segments (datacenter, network & storage, connected consumers, and Embedded & IoT):

  • Linux -  Optimizations for enterprise, home and embedded Linux.
  • Android – Getting started with Android, and Android source code
  • Developer Tools – Used in conjunction with Android and Linux OS
  • Virtualization & Secure Supervisor – Secure multi-container frameworks
  • OpenWRT – Enabling carrier-grade features to complement OpenWRT
Arduino Yun

Arduino Yun

It also appears some low cost MIPS32 & MIPS64 development board and reference designs will be supported such as Newton wearable platform, Microchip chipKit WF32 board, and Arduino Yun.

Companies can join Prpl as Board Members or Contributors Members, and individuals can join the foundation for free to engage with the community and access source code and tools.

Since the the Prpl foundation has just been launched, there aren’t any tools or software available right now, but if you are interested in MIPS development, and possibly other architecture which may be part of Prpl later on, you can get more information and/or join the foundation on Prpl Foundation Website.

Snapdragon 600 based IFC6410 Development Board is Available for $75 For a Limited Time

May 9th, 2014 12 comments

Despite their popularity with tablets and smartphones, I don’t see much developer community around Qualcomm Snapdragon processor, and only a few low cost development boards. One of them is Inforce Computing IF6410 pico-ITX board powered by Qualcomm Snapdragon 600 (APQ8064) quad core processor with 2GB RAM, 4GB eMMC flash, Gb Ethernet, Wi-Fi, Bluetooth, SATA,  micro HDMI and LVDS video outputs, etc.., that normally sells for just $149.

But the company is having a promotion for $75 with the coupon code “makerfaire” until May 18, or until the 500 units they’ve reserved are sold out. Shipping is not included in the price, and you’ll have to add about $50 for Fedex delivery (It may be cheaper in the US) for a total of about $125, which still probably makes it the cheapest “Cortex A15 class” board that you can get. The board appears to only officially support Android, and if you want to run a Linux distribution you may need to so so within Android (TBC).

Thanks to adem for the tip.
