== Chipset specifications == 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 [[Digital signal 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 Linux systems that could be used as a middle-ware, like for example [[OpenMAX]] or [[VAAPI]].

=== A-Series ===

The A-series are integrated application processors primarily targeting tablets as well as targeting mini PCs, development boards and TV boxes.<ref name="Allwinner homepage" />

== Allwinner processor ecosystem == {{Unreferenced section|date=July 2017}} [[File:Allwinner IDH List.jpg|thumb|Allwinner IDH List]] Allwinner Technology cooperates with around ten [[independent design house]]s (IDHs) based in Shenzhen, China, who develop solutions based on Allwinner processors. They include iNet Technology, Worldchip Digital Technology, Sochip Technology, Topwise Communication, ChipHD Technology, Highcharacter Science and Technology, WITS Technology, Ococci Technology, Next Huawen Technology, and Qi Hao Digital Technology.

Apart from the [[white box (computer hardware)|white-box]] market, Allwinner processors can also be found in many brand products, including [[HP Inc.|HP]], [[Micro-Star International|MSI]], [[ZTE]], NOOX, GoTab, Skyworth, MeLE, [[Polaroid Corporation|Polaroid]], Micromax, Archos, Texet, Ainol, Onda, Ramos, [[Teclast]], Ployer, Readboy, Noah, RF, Bmorn, Apical, Astro Queo, etc.

== Free and open-source software support == Due to the low price of the A10 SoC, the fact that it has a special rescue mode, and the early availability of [[Das U-Boot|U-Boot]] and Linux kernel source (through several device makers), the Allwinner SoCs have been popular among open-source software developers. Since at least 2012 the linux-sunxi community has been one of the most active ARM SoC communities, and the slightly older hardware has only very minimal dependence on firmware or blobs.<ref>[https://linux-sunxi.org/ Sunxi Community website]</ref><ref>[https://fosdem.org/2014/schedule/event/arm_allwinner_sunxi_socs/ FOSDEM talk about the Sunxi Community] on the FOSDEM website.</ref>

Since 2014, Allwinner is also an official member of the [[Linaro]] group, a nonprofit engineering consortium aimed at developing open-source software for the [[ARM architecture]].<ref>[http://www.linaro.org/news/linaro-announces-allwinner-technology-as-a-founding-member-of-the-new-linaro-digital-home-group/ Announcement of Allwinner membership] on Linaro news site.</ref> However, it has been noted that most of the contributions that Allwinner has made to the Linaro group has been in the form of binary blobs, which is in clear violation of the [[GPL license|GNU GPL license]] that the Linux kernel uses.<ref name=":3" />

Allwinner has been accused multiple times<ref name=":3">{{cite web |title=GPL Violations |url=http://linux-sunxi.org/GPL_Violations |access-date=2016-01-30 |publisher=linux-sunxi.org}}</ref> of violating the [[GNU General Public License|GPL license]] by not providing Linux/Android kernel source code or U-Boot source, and by using [[GNU Lesser General Public License|LGPL]]-licensed code within their binary blobs, etc.<ref>{{cite web |date=2015-03-19 |title=Allwinner Caught Obfuscating Their Improperly Licensed Code |url=https://www.phoronix.com/scan.php?page=news_item&px=Allwinner-Obfuscating-Code |access-date=2016-01-30 |publisher=Phoronix}}</ref>

Allwinner has also been accused of including a [[Backdoor (computing)|backdoor]] in its published version of the Linux kernel.<ref>{{cite news |last1=Gallagher |first1=Sean |date=11 May 2016 |title=Chinese ARM vendor left developer backdoor in kernel for Android, "Pi" devices |url=https://arstechnica.com/security/2016/05/chinese-arm-vendor-left-developer-backdoor-in-kernel-for-android-pi-devices/ |access-date=11 May 2016 |publisher=Ars Technica}}</ref><ref>{{cite news |last1=Chirgwin |first1=Richard |date=9 May 2016 |title=This is what a root debug backdoor in a Linux kernel looks like |url=https://www.theregister.co.uk/2016/05/09/allwinners_allloser_custom_kernel_has_a_nasty_root_backdoor/ |access-date=11 May 2016 |publisher=The Register}}</ref> The backdoor allows any installed app to have full root access to the system. While this may be a remnant of debugging during the development process, it presents a significant security risk to all devices using the Allwinner provided kernel.
