This is shown by the darkest color on the graph (Cluster Off). When a CPU has been idled for a long enough period, the system power control software may take a core to a full shutdown to save leakage power. The light blue regions in the graph indicate this idle time (WFI and OFF). In addition to the DVFS states, the OS power management can idle a CPU. In the diagram, the red color indicates the highest frequency operating point, while the green colored regions indicate the lowest frequency operating point, and colors in between represent intermediate frequencies. The graph above shows the percentage of time spent in DVFS states, and in idle and full shutdown states, by two cores in a currently shipping Cortex-A9 based mobile device. One of the characteristics that makes big.LITTLE advantageous is the varied performance requirements of typical mobile workloads. More information on A80 octa core will be disclosed during CES. In addition, A80 packs a cutting-edge OpenGL ES 3.0 compliant, GPU compute optimized graphics processor to deliver the best performance while keeping the smallest area and lowest power consumption. Touted as Ultra Octa Core, Allwinner A80’s CoolFlex TM – powered multi-CPU architecture enables low power, high peak performance devices.

Expo visitors are welcome to visit at LVCC-South Hall S-2, MP25563. As the leading mobile application processor design company, Allwinner Technology will showcase during CES its latest flagship Ultra Octa Core A80 development board, named OptimusBoard, 4G tablets powered by Allwinner A31/A31s, and dual-SIM phablets sporting A23 dual core. The 2014 International Consumer Electronics Show (CES) will take place in Las Vegas from January 7 to January 10. This the first product to be delivered on schedule from the announced earlier roadmap of Three octa-cores and two more quad-cores to enhance the Allwinner SoC portfolio in the next two and one year respectively : Allwinner “Ultra Octa-Core” A80 OptimusBoard to be Unveiled at 2014 CES

Allwinner is shipping these boards in Q1 2014, if anyone is interested to start developing with A80, they should contact Allwinner here: With potential support for Chrome OS, ultra-fast Ubuntu, advanced ARM projects to use extreme parallel processing. Allwinner launches A80 Octa Core ARM Cortex-A15 with ARM Cortex-A7 in big.LITTLE MP OctaCore configuration with the PowerVR6 series GPU with OpenGL 3.0 with GPU Compute.
