Samsung Wide IO Memory Interface for the faster and lower power ARM Processors of the future

Posted by – November 21, 2013

Memory bandwidth is one of the most important features in an SoC to get performance. Here presenting Samsung’s new memory architecture, possibly (my guess) to be used in Exynos6 (64bit) possibly at 20nm or perhaps even 14nm even, Samsung talks about their upcoming Wide-IO faster Memory Interface architecture for future ARM Processors to input and output much faster memory bandwidth. To run the same workload, it can use 60-70% less power of the memory plus memory interface power within the SoC, which is a large part of the power consumption within an ARM SoC, Samsung is ready with the technology. The business is about the timing, they are aiming for the best timing to introduce this technology. Provides for example 17gbit/s memory bandwidth, allowing to increase memory bandwidth possibly above 100gbit/s, to be confirmed as better technology is implemented. The history of LP-DDR is to increase the frequency to increase memory bandwidth, but with Samsung’s Wide-IO memory design, they can increase the memory lines instead and thus achieve much better memory bandwidth, possibly running 2-3x faster memory bandwidth at the same frequency, perhaps something like 50gbit/s easily. The demand for the memory bandwidth for smartphone devices will surpass memory bandwidth for the traditional desktop PC.

Samsung Exynos5420 HMP big.LITTLE demo

Posted by – November 21, 2013

Samsung shows HMP big.LITTLE mode working on the Exynos5420, Heterogeneous Multi Processing means that you can manage the 8 big.LITTLE cores independently and use them all at the same time. Showing HMP mode achieving a higher benchmark result over IKS process switching mode on the same CPU and on the same exact tablet hardware. Even being able to do full Octa Core Exynos5420 CPU and the full 6-core Mali-T628 GPU performance using renderscript at the same time heterogeneously achieving the maximum performance and at the same time also improving battery life when doing the same task. Showing here some advanced photo editing app using renderscript to optimize performance of that type of app.

HP Chromebook 11 unboxing and first boot

Posted by – October 29, 2013

I decided to buy a $279 ($303 with taxes) HP Chromebook 11 with the Exynos5250 Dual-core ARM Cortex-A15 with Mali-T604 inside, even though it would have been nice if it already would have been shipping with the newer Exynos5420 Octa Core ARM Cortex-A15/A7 with Mali-T628. I guess that Samsung doesn’t yet provide their latest big.LITTLE yet for third parties to ship in devices? As soon as a good cheap 13.3″ Exynos5420 Chromebook is available I’ll probably switch to that latest ARM Chromebook as my main video-blogging laptop.

$65 VIA8880 10.1″ Laptop, $41 RK3026 7″ Tablet and more from Wabook

Posted by – October 20, 2013

Wabook shows their latest range of low priced tablets, now featuring Rockchip RK3026 and Allwinner A23 to lower prices and to increase the performance at lower power consumption, also showing RK3188 and A31S tablets, then also showing Wabook’s new and improved ARM Powered Laptop design now using the new VIA WM8880 dual-core ARM Cortex-A9 processor, now with a better chiclet keyboard, a better larger mousepad, better mouse buttons, better USB Host port designs and more, priced at $65 in bulk. Wabook now says Chrome OS on that is a possibility.

AmLogic M802 2Ghz Quad-core ARM Cortex-A9, TSMC 28nm, 8-core Mali-450 GPU, supports 4K

Posted by – October 19, 2013

AmLogic shows their new M802 Quad-core ARM Cortex-A9 (28nm TSMC) with 8-core Mali-450 GPU, showcased in the new Geniatech ATV580 4K Set-top-box, 7.85″ Tablets, 9.7″ Retina tablets, 13.3″ Laptops and more, all running Android 4.3 with mostly 2GB RAM and 4K video playback support. AmLogic claims to provide higher benchmark scores than competing quad-core Rockchip and Allwinner solutions on the market. The AmLogic M802 has dual-channel DDR3 RAM for 4K and Retina screens while the AmLogic M801 has a single-channel DDR3 RAM support for lower resolution devices without 4K support.

Allwinner A80 Octa ARM Cortex-A15/A7 big.LITTLE, A70 quad A15/A7, A90 ARMv8 64bit, A23 Dual A7

Posted by – October 14, 2013

Allwinner announced their upcoming Allwinner A80 Octa-core with four ARM Cortex-A15 cores and four ARM Cortex-A7 cores configured in a big.LITTLE configuration, the release to happen around Q1 2014. As well as the Allwinner A70 Quad-core (2x Cortex-A15 and 2x Cortex-A7), and for later, Allwinner already announces that they will release a 64bit ARMv8 ARM Cortex-A57 and ARM Cortex-A53 big.LITTLE processor, perhaps for later in 2014 or for early 2015. For the first time, Allwinner shows the Chrome logo, Windows 8 (probably meaning Windows RT), this means the Allwinner A80 may be good to use in mass market affordable Chromebooks, cheap Windows RT laptops and desktops and more. This video also features the Allwinner A23 PCB, implemented in affordable 7.85″ tablets and more, manufactured now by Pegatron and Foxconn, Ramos, Onda, Winn and many more. Allwinner is the leading Quad-core and Single-core chip provider for tablets worldwide.

Planned Obsolescence and IEEE’s new P1874 standard presented by William Lumpkins of IEEE

Posted by – October 13, 2013

IEEE launches the P1784 Standard for Documentation Schema for Repair and Assembly of Electronic Devices for users and the industry working together to make all devices easily repairable by people themselves by just looking up how to fix everything online. Standard for documentation for showing how to take devices apart and fix it one self, without needing to send devices back for repair, but also enabling more repair centers to be opened up everywhere.

HP Chromebook 11 launched $279, Exynos5250 (dual-core ARM Cortex-A15, Mali-T604)

Posted by – October 8, 2013

Yes! The Second ARM Chromebook is now released for $279, made by HP. But wait, still same Exynos5250? Why no Octa? Isn’t that the exact same Exynos5 Dual processor Samsung used in Samsung Chromebook released a year ago? Maybe it’s tweaked. This HP Chromebook 11 sounds to have a better IPS display, better build quality perhaps, MicroUSB charging (is it a 5A or at least 2A MicroUSB charger?) The really good news is that Samsung is providing its Exynos5 for ARM Chromebooks by third parties, such as the huge HP. It would be nicest to see Exynos5420 in there though. 28nm vs 32nm, Octa big.LITTLE vs Dual, Mali-T628 vs Mali-T604, 1.9Ghz vs 1.7Ghz, etc.
