Allwinner Technology is a China-based fabless semiconductor company that designs mixed-signal SoCs and provides total system solution. Headquartered in Zhuhai, Guangdong the company currently employs about 500 people – 80% of which are engineers. It has a sales and technical support office in Shenzhen, China, and logistics operations in Hong Kong.
Since its founding in 2007, Allwinner has released more than fifteen SoC processors that have been widely implemented in Android-based tablets, as well as in smartphones, Android internet boxes / set-top boxes, video camera systems, car DVRs, and car media players. In 2012, Allwinner was the number one supplier in terms of unit shipments of application processors for Android tablets worldwide.
From 2007 to 2011, Allwinner introduced its F-series processors, F10, F13, F18, F20, F1E200, F1C100, F20. This series runs Allwinner's self-developed operating system Melis2.0, which is now mainly used in vehicle multimedia system, E-ink reader, Visual intercom system etc.
In 2011, the company became an ARM processor licencee, and subsequently announced a series of ARM Cortex-A8 powered mobile application processors, including A10, A13, A10s and A12, which were used in numerous tablets, and also in PC-on-a-stick and media center devices. They have also been adopted in free hardware projects like the Cubieboard development board.
A2x and A3x family
In December 2012, Allwinner announced the availability of two ARM Cortex-A7 MPCore powered products, the dual-core Allwinner A20 and quad-core Allwinner A31. Production of the A31 started in September 2012 and end products, mostly high-end tablets from Chinese manufacturers, appeared on the market in early 2013, including the Onda V972. Allwinner was the first to make this ARM processor available in mass production.
In March 2013, Allwinner launched its quad-core Phablet processor A31s. Based on quad-core cortex-A7 CPU architecture, this processor allows 3G, 2G, LTE, WIFI, BT, FM, GPS, AGPS and NFC using a minimum of external components.
In October, 2013, Allwinner released its second dual-core A23, touted to be "The most efficient dual core processor" for tablets.[dead link] The A23 CPU frequency runs up to 1.5 GHz, and test data indicated that the power consumption of an A23-powered tablet is low, music playback power consumption (offscreen) can be as low as 48mA.
In June, 2014, AllWinner announced the A33 Quad Core SoC, that is Pin-to-Pin Compatible with AllWinner A23. The new soc features 4 Cortex-A7 cores with 256 KB L1 Cache, 512KB L2 cache and a Mali-400MP2. A new feature is the support of OpenMAX API. This chip doesn't support nativly SATA.
On Oct 10, 2013, Allwinner released its product roadmap in 2014 and 2015, indicating that octa-core and wearable processors were on the way.
The V-Series are video encoding processor targeting applications such as smart DVR, IP camera and smart home applications. It has a similar configuration of the A series SoC, but with extra feature such as Digital watermarking, Motion detection, CBR/VBR bit rate control mode. 
The Allwinner SoC family includes A-series, which is intended for Android OS, and F-series, which is intended for the company's self-developed Melis operating system.
The A-Series, including the A10, A20 and A31 SoCs, have a proprietary in-house designed multimedia co-processing DSP (Digital Signal Processing) processor technology for hardware accelerated video, image, and audio decoding, called CedarX (with subprocessing called "CedarV" for video decoding and "CedarA" for audio decoding), able to decode 2160p 2D and 1080p 3D video. The main disadvantages with CedarX technology and associated libraries is that Allwinner's own CedarX proprietary libraries have no clear usage license, so even if the source code for some versions is available the terms-of-use is unknown in open source software, and there is no glue code for any other multimedia frameworks on GNU/Linux systems that could be used as a middle-ware, like for example OpenMAX or VAAPI.

Free and open-Source support
Due to the cheap price of the A10 SoC, the fact that it has a special rescue mode, and the early availability of u-boot and linux kernel source (through several device makers), the Allwinner SoCs has been very popular with open source software developers. The linux-sunxi community is currently one of the most active ARM SoC communities, and the hardware has only very minimal dependence on firmware or binary blobs.
