The Allwinner A1X, known under Linux as sunxi, is a family of single-core SoC devices designed by Allwinner Technology from Zhuhai, China. Currently the family consists of the A10, A13, A10s and A12. The SoCs incorporate the ARM Cortex-A8 as their main processor and the Mali 400 as the GPU.
The Allwinner A1X is known for its ability to boot GNU/Linux distributions such as Debian, Ubuntu, Fedora, and other ARM architecture-capable distributions from an SD card, in addition to the Android OS usually installed on the flash memory of the device.

Storage and boot devices
Many manufacturers have adopted the Allwinner A1X for use in devices running the Android operating system and the Linux operating System. The Allwinner A1X is used in tablet computers, set-top boxes, PC-on-a-stick, mini-PCs, and single-board computers.
- PengPod, Linux-based 7 and 10-inch tablets.
- Vivaldi Tablet, a tablet computer based on the Allwinner A10. The project is being conducted by Aaron Seigo and it's operating system features the KDE Plasma Workspaces
- Gooseberry, a board based on the A10 SoC similar to the Raspberry Pi.
- Cubieboard, a board based the A10 SoC.
No factory sourced programmers manual is publicly available for the A10S CPU at this moment.
There is a work in progress on support Efika on FreeBSD. At the moment, not all on-board peripherals are working. http://lists.freebsd.org/pipermail/freebsd-arm/2012-December/004446.html
Apart from the single-core A1x (A10/A13/A10s/A12), two new more powerful Cortex-A7 Allwinner SoCs have been announced by Allwinner, the A10-pin-compatible dual-core Allwinner A20, and the quad-core Allwinner A31.
