Allwinner A1X

One of the many single-board computers based on the Allwinner A10 SoC.

The Allwinner A1X is a family of single-core SoC devices designed by Allwinner Technology from Zhuhai, China. Currently the family consists of the A10,[1] A13,[2] A10s[3] and A12. The SoCs incorporate the ARM Cortex-A8 as their main processor[4] and the Mali 400 as the GPU.

The Allwinner A1X is known for its ability to boot 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.

A1x Features

A generic tablet based on the Allwinner A13 core.

Video acceleration

  • HD video decoding (up to 3840x2160)
  • Supports popular video codecs, including VP8, AVS, H.264 MVC, VC-1, and MPEG-1/2/4[1]
  • HD Video Encoding (H.264 High Profile)

Implementations

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.

Linux support

The Allwinner A1X architecture is referred to as 'sunxi' in the Linux kernel source tree. The source code is available at GitHub.[9] At the moment, stable and full hardware support is limited to 3.0.x and 3.4.x kernels. Recent mainline versions of the kernel run, but do not offer NAND access and have only limited 3D-acceleration.[10]

FreeBSD support

There is a work in progress on support Efika on FreeBSD. At the moment, not all on-board peripherals are working.[11][when?]

OpenBSD support

As of May 2015, OpenBSD's armv7 port supports the Cubieboard and pcDuino boards based on the Allwinner A1X.[12]

NetBSD support

NetBSD contains support for the Allwinner A10.[13]

Documentation

No factory sourced programmer's manual is publicly available for the A10S CPU.

Allwinner A-Series

Apart from the single-core A1x (A10/A13/A10s/A12), two new more powerful Cortex-A7 Allwinner SoCs have been released by Allwinner, the A10-pin-compatible dual-core Allwinner A20, and the quad-core Allwinner A31.[14]
