H88 HummingBird Development Board Powered by Allwinner A80 Comes with 4GB RAM, Built-in GPS, 4G LTE Support

Merrii Technology is having some fun churning out Allwinner A80 development boards, and after A80 OptimusBoard, H8 Hummingbird, here comes H88 HummingBird. The new board is somewhat similar to H8, but is quite larger, and features 4GB RAM, built-in GPS, and a few other goodies. H88 HummingBird specifications: SoC – AllWinner A80 octa-core processor with 4x Cortex 15, 4x Cortex A7 cores in big.LITTLE configuration with Imagination Technologies PowerVR GC6230 GPU compliant with OpenGL ES 3.0/2.0/11, OpenCL 1.1, and DirectX 9.3 System Memory – 4GB DDR3 Storage – 8GB internal storage (Hynix H27UCG8T2BTRBC), micro SD slot up to 32 GB Video Output/ Display Interfaces HDMI 1.4 up to 4K UHD resolution RGB/LVDS interface EDP LCD + TP interface MIPI LCD interface VGA output Audio – HDMI, headphone jack,LINE-IN, Camera I/F – Parallel and MIPI CSI interface. Integrated 16MP camera Connectivity – Gigabit Ethernet (Realtek RTL8211D/E), dual band Wi-Fi 802.11 b/g/n […]

Fujitsu MB86S70 and MB86S73 ARM Cortex A15 & A7 Processors Run Linux for the Embedded Market

I like to check the ARM Linux kernel mailing list from time to time, as you may discover a few upcoming ARM processors. This week I found out Exynos 5433 and Exynos 7 are actually two different processors (thanks David!), and that AMD had submitted code for their 64-bit ARM Opteron A1100 SoC for servers. I also noticed a patchset for Fujitsu MB86S7X SoCs, and since I don’t often mention Japanese silicon vendors, probably because they now mainly deal mostly with the embedded market that gets very little press, and most information is in Japanese, I decide to have a look. There seems to be four SoC parts in MB86S7x family with MB86S70 quad core processor with two ARM Cortex A15 and two ARM Cortex A7 cores in big.LITTLE configuration, and MB86S73 with two ARM Cortex A7 cores only, as well as MB86S71/72 with 2x A15 and 2x A7, with […]

AllWinner A80 Octa Core big.LITTLE Processor CPU Usage Under Various Loads in Android 4.4 (Video)

Allwinner A80 is one of the few octa core processors featuring ARM’s big.LITTLE technology currently available on the market. The processor comes with four ARM Cortex A15 (big) cores, and four ARM Cortex A7 (LITTLE) core, and tasks will be scheduled to different processor depending on the load to optimize power consumption on mobile devices. However, earlier big.LITTLE processors like Samsung Exynos 5410 has some serious limitations, as they only supported “cluster migration” meaning you could only use the Cortex A7 cluster or Cortex A15 cluster at any given time, so Exynos 5410 could only make use of four cores at most due to hardware limitations. They also used to be two software implementations: In-kernel Switching (IKS) and Global Task Scheduling (GTS). The former could only handle one type of core at the same, and the latter, which I believe is now used in all new devices, can handle any […]

Tronsmart Draco AW80 is an Allwinner A80 Android mini PC with Up to 4GB RAM

An Allwinner A80 board for TV boxes / mini PC started to show up in the upcoming Z8C Alice TV box a few weeks ago, and the board, or another one with exactly the same layout, made it into Tronsmart Draco AW80 Meta and Telos mini PCs with respectively 2GB RAM/16GB eMMC, and 4GB RAM/32GB eMMC, and selling for $149.99 and $199.99 on GeekBuying. Tronsmart Draco AW80 Meta/Telos specifications: SoC – AllWinner Ultra Core A80 4x Cortex 15, 4x Cortex A7 big.LITTLE processor with Imagination Technologies PowerVR GC6230 GPU with support for OpenGL ES 1.1/2.0/3.0, Directx 9.3 System Memory – 2GB (Meta), or 4GB (Telos) DDR3 Storage – 16 GB (Meta) or 32GB (Telos) eMMC + SD card slot + SATA port (via a USB 2.0/3.0 bridge) Video Output – HDMI 1.4b + AV port Audio – HDMI, AV, and optical S/PDIF (Main) Video Codecs – H.265/VP9 up to 1080p […]

Samsung Officially Announces Exynos 7 Octa big.LITTLE ARM Cortex A53/A57 Processor

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. Here’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 […]

Allwinner A80 Android TV Boxes Coming Soon, Starting with Zero Devices Z8C Alice

Allwinner A80 based tablets such as Onda V989, and development boards such as A80 OptimusBoard started to ship one to two months ago, but there was absolutly no news about Android mini PCs / media player based on the latest Allwinner processor. This is about to change as ZeroDevices twitted about their Z8C Alice TV Box, apparently designed by Sunchip, and in collaboration with a UK based digital signage company called Eclipse Digital Media. Preliminary technical specifications that we can infer from the picture above: SoC – AllWinner Ultra Core A80 4x Cortex 15, 4x Cortex A7 big.LITTLE processor with Imagination Technologies PowerVR GC6230 GPU with support for OpenGL ES 1.1/2.0/3.0, Directx 9.3 System Memory – N/A Storage – ?? GB eMMC + SD card slot + SATA port (most probably via a USB 2.0/3.0 bridge) Video Output – HDMI + AV port Audio – HDMI, AV, and optical S/PDIF […]
