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.

Android 5.0 Lollipop Coming to Allwinner A33 & A80, Rockchip RK3288, and More…

November 17th, 2014 7 comments

I can often see questions requesting whether SoC XYZ will support Android 5.0 Lollipop. The good news is that last week, I’ve read lots of news about Android 5.0 support on various devices including Nvidia Shield tablet, Motorola G & X smartphones, and of course the Google Nexus devices. A developer (Nanik T.) also ported Android Lollipop to ODROID U3 development board based on Exynos 4412, and he mentioned that “porting was pretty straight forward as KK and 5.0 does not have a lot of differences in terms of HAL”, which means there’s hope for more recent devices and SoCs getting the update.

Rockchip_RK3288_LollipopChinese SoC vendors are also getting the word out that they are working on Android 5.0. Rockchip announced Lollipop support for RK3288 processor (original news in Chinese) probably coming to tablets first, and Android TV boxes later. They used their reference platforms in the provided pictures, and did not publish ETA for public availability.

Allwinner also showcased Android 5.0 on an Allwinner A33 tablet (see embedded video below), and I’ve been told Android 5.0 and Chrome OS would soon be released for Android A80 too.

XDA Developers also reported some other smartphones got the Lollipop treat.

Imagination Technologies Introduces PowerVR Series7 GPUs with Up to 512 Cores, Virtualization Support

November 10th, 2014 3 comments

Imagination Technologies has announced a new PowerVR Series7 GPU architecture that will be used in their high end PowerVR Series7XT GPUs delivering up to 1.5 TFLOPS for mid range and high-end mobioe devices, set-top boxes, gaming consoles and even servers, as well as their low power lost cost PowerVR Series7XE GPUs for entry-level mobile devices, set-top boxes, and wearables.

PowerVR_Series7XT_Block_Diagram

PowerVR Series7XT GPU Block Diagram

PowerVR Series7 GPU, both Series7XT and Series7XE GPUs, can achieve up to a 60% performance improvement over PowerVR Series6XT/6XE GPUs for a given configuration. For example a 64-core PowerVR7XT GPU should be up to 60% faster than a 64-core PowerVR Series6XT clocked at the same frequency, with all extra performance due to a different and improved architecture.

Some of Series7 architectural enhancements include:

  • Instruction set enhancements including added co-issue capability, resulting in improved application performance and increased GPU efficiency
  • New hierarchical layout structure that enables scalable polygon throughput and pixel fillrate improvements in addition to increased clock frequencies
  • GPU compute setup and cache throughput improvements resulting in up to 300% better parallel processing performance

The new GPUs can also optional support 10-bit YUV color depths, security (e.g. DRM), and hardware virtualization, as well as other feature specific to some market segments:

  • Android Extension Pack (AEP) – Full hardware tessellation and native OpenGL ES 3.1 support. Compatible with Android 5.0 ‘Lollipop’ release.
  • DirectX 11 Feature Pack – Full DirectX 11.2 feature set for Microsoft operating systems.
  • OpenCL FP64 Feature Pack –  Scalable 64-bit floating point co-processor per cluster for high-performance server compute. Series7XT only.
PowerVR Seris7XE Block Diagram

PowerVR Seris7XE Block Diagram

The PowerVR Series7XT family scales between 100 GFLOPS to 1.5 TFLOPS, and is designed to provide the best possible performance. It features AEP and 10-bit YUV support by default, and supports between two to sixteen clusters with 32 multi-threaded multi-tasking ALU cores each. Current Series7XT GPUs include the GT7200 (64 cores),  GT7400 (128 cores), GT7600 (192 cores),  GT7800 (256 cores), and GT7900, the most powerful PowerVR GPU to date with 512 cores.

On the other hand, Series7XE GPUs are optimized for area, efficiency, and cost thanks to feature configurability, with let SoC manufacturers choose whether they want options such as 10-bit YUV support for HEVC, virtualization, or AEP support. Beside low cost mobile devices and media player, Series7XE GPU are also expected to be used in photocopiers, printers, consumer and other enterprise devices which may require 3D user interfaces at a lower price point. There are two GPUs part of the Series7XE family: GE7400 with 16 cores, and the GE7800 with 32 cores.

The company will provide their usual free PowerVR SDK for 3D graphics and GPU compute application development. Hypervisors will be able to utilize the virtualization in the GPUs to implement true heterogeneous security in any of the PowerVR Series7 GPUs (if virtualization is enabled).

PowerVR Series7XE and Series7XT GPUs are available for licensing now, and Imagination Technologies has already started implemention their new GPU IP into SoCs from licensing partners. More technical details about be found on two blog post: New PowerVR Series7XE family targets the next billion mobile and embedded GPUs and PowerVR Series7XT GPUs push graphics and compute performance to the max.

THL T6 Pro and AXGIO Neon N2Q Octa-core Android Smartphones Sell for $117

November 6th, 2014 13 comments

I’ve just noticed some Mediatek MT6592 octa-core Android smartphones are selling for a little over $100. The cheapest phones seem to be THL T6 Pro and AXGIO Neon N2Q both selling for exactly $116.99, the former on sites like GeekBuying or BuyInCoins, and the latter only selling on Tinydeals, so AXGIO may be a re-branded phone. Let’s compare both phones.

Since most phones now look pretty much alike, we’d better look at the hardware specifications instead to eventually decide is better value for money.

Accessories Battery, earphones, USB cable, power adapter, back case, and user’s manual Battery, earphones, USB cable, power adapter, protective case, protective PU leather case, and user’s manual

Both phones runs Android 4.4.2, but the AXGIOS Neon N2Q has an option to run “Neonato UI with OTA support, multiple themes, and more personalized features”, which could mean you are more likely to get firmware update for Neon N2Q, although I would not hold my breath for long term updates… Any both phones are pretty similar, but ThL has a better display, and possibly a better camera (TBC), whereas Neon N2Q has a slightly larger battery and somehow is about 24 grams lighter.

Sellers may also offer some gifts with the phone, but I still find the better 720p display should mean ThL T6 Pro is a better product, at least on paper. Having said that, I’ve owned a ThL smartphone, namely ThL W200, for over a year, and I’ve been disappointed with GPS and the camera not working reliably over time. But maybe that’s something to expect with lower cost phones.

Thanks to Onebir for the idea.

Add Wireless Charging to (Almost) Any Smartphone or Tablet

October 27th, 2014 5 comments

Flagship mobile devices often come with wireless charging capability, but there’s an easy way to add (Qi) wireless charging to almost any smartphone, or possibly tablet, thanks to wireless charging receivers that simply connect to the micro USB port of your mobile device, and can be purchased for as low as $7 on Aliexpress, Ebay, DX.com, etc… I’ve also seen Adafruit made a Qi Wireless Receiver module for Arduino with a 2.54mm pitch connector.

Qi_Wireless_Charger_ReceiverThey come in various sizes and shapes, but they’re all extra thin (1 mm), with a micro USB connector oriented upwards or downwards depending on your mode, and a thin cable, that allows you to place it inside your phone between the battery and the phone cover as shown in the picture below. It’s not always possible however, as for example the receiver would cover my phone’s rear camera lens, but you could always attach it to a protective cover, or a car phone holder.

Wireless_Charger_Receiver_Phone

Once the installation is complete, you are ready to charge your phone with a wireless charger.

Specifications ARE different between modules, but typically look like:

  • Dimensions – 62 x 45 x 1.1mm
  • Net weight – 2.5g
  • Input Power – 3.5W
  • Output – DC5V/650mA (Average)
  • Charging current – DC5V/500mA (Average)
  • Working life – 4000 charges

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.
