Octa-Core CPU Performance/Power Tuning on the Allwinner A80T

Posted by – July 18, 2014

This video shows one of the automated performance testing tools used during A80’s big.LITTLE tuning process. big.LITTLE is an innovative technology used to balance Cortex-A7’s low power with Cortex-A15’s high performance. An important part of the tuning process is frequent regression testing – that is, checking how performance and power consumption are affected by firmware updates. In this video, a simple automated benchmark test is running after a firmware update.

Quick-and-dirty tests like these allow software engineers to more efficiently check system performance and power consumption after low-level parameter changes.

PowerVR G6230 64-Core GPU Tuning on the Allwinner A80T

Posted by – July 18, 2014

This video shows one of the GPU tuning tools (PVRTune) used during A80 development. To run the tests, an A80T tablet is hooked up to a host computer running PVRTune. A tester can then operate different use cases on the tablet (scrolling through the GUI, playing games, etc) while seeing how GPU load is affected on the host computer’s PVRTune display window. In this video, we see how the GPU’s 3D engine is loaded while scrolling through Android’s stock GUI. When performance bottlenecks are spotted, this tool can help engineers better distinguish CPU/GPU root causes, increasing debugging efficiency.

Allwinner A80T Onda V989 Tablet now shipping! new Smart features!

Posted by – July 17, 2014

The first tablet based on the Allwinner A80 is now shipping out of China! It’s the Onda V989, using the nice ultra slim iPad Air display, this tablet looks extremely sleek and nice. Here Allwinner is showing off some of their new Smart features, including the cool “always on” sensor that wakes the device up with just a double-touch of the display (similar to LG knock-on feature, and similar somewhat to previous Moto X sensor fusion stuff), they also have a few head-tracking Smart functions that they added in settings, taking advantage of their hardware accelerated head-tracking feature: Smart Pause pauses video when you look away from the screen, Smart Rotate does not rotate the screen when you for example lie down on the bed, Smart Stay means the screen always stays on if you are still looking at it when the dimming setting kicks in (it overrides screen dimming). More specs, pricing, and other stuff to follow, let me know what you might like me to test on this tablet in a next video about it.

Onda V989 Specs, Price:
Ultra-light, extremely narrow bezel 9.7” 2048×1536 IPS LCD
OctaCore A7/A15 CPU
64-Core PowerVR G6230 GPU

MediaTek LinkIt Aster MT2502, new SoC for entry-level Smartwatches

Posted by – July 12, 2014

MediaTek launches the Linkit platform called Aster MT2502, combining the MCU, PMIC, Bluetooth, Memory and Modem all into one chip. Lowering the power consumption, lowering the size, and even lowering the cost, MediaTek also introduces the Tiny System that kicks-in to standby mode on a lowered 26Mhz CPU frequency, down from a peak of 260Mhz that this MT2502 is designed to run at. When the Smartwatch is in use, it runs on RTOS Nucleus OS, running basic Smart functions with built-in Bluetooth 4.0 Low Energy. Thus lower power (runs up to 4 days) compared to the existing MediaTek MT6260 platform which already runs a whole range of sub-$30 Smartwatches on the market. Supports QVGA 320×240 displays only, MediaTek is working with all kinds of different display providers including also E Ink. To accelerate development on their Linkit, MediaTek launches the MediaTek Labs providing a development board with SDK, find more information at http://www.mediatek.com/en/labs/

My father’s funeral – part 3 of 3

Posted by – July 6, 2014

A year ago, my father was buried here. This has been the hardest year of my life, without him guiding me, without his comment and without him telling me what to do. Nobody to sit in his chair, nobody to see what he would have seen, a mystery of his past.
