AllWinner Publishes A31 and A20 Processors Details

Several tablets based on AllWinner A31 quad core processor have been announced this week,  such as Onda V972, but we did not really have full details on the processor. We now know more since AllWinner added product pages for two new (sun6i architecture. [Edit: A20 is actually sun7i…]) processors: AllWinner A31 and AllWinner A20.

The platform supports Android 4.2 and Microsoft Windows RT, but there’s no word about Linux. More on that at the end of the post.

AllWinner A20 Specifications

AllWinner A20 is a dual core Cortex A7 processor with a dual core Mali-400 GPU.

  • CPU – ARM Cortex-A7 Dual Core with 512MB L2-Cache*/128KB L1-Cache (* As per AllWinner A20 page, but this should most definitely read as “512KB L2-Cache”)
  • GPU – ARM Mali400 MP2
  • Memory – LPDDR2/DDR3/DDR3L controller, NAND Flash controller and 64-bit ECC
  • Video
    • HD H.264 2160P video decoding
    • Full HD video decoding
    • BD Directory, BD ISO and BD m2ts video decoding
    • H.264 High Profile [email protected] encoding

    • Complies with RTSP, HTTP,HLS,RTMP,MMS streaming media protocol
  • Display
    • Support multi-channel HD display
    • Integrated HDMI 1.4
    • CPU/RGB/LVDS LCD interface 1920×1080 resolution
    • CVBS/YPbPr/VGA support
    • Integrated TV decoder
  • Camera
    • Integrated parallel 8-bit I/F YUV sensor
    • Integrated 24-bit parallel YUV 444 I/F
    • 5M/8M CMOS sensor support
    • Dual-sensor support
  • Audio
    • Integrated HI-FI 100dB Audio Codec
    • Dual MIC noise cancellation

AllWinner A20 supports Android 4.2 or above. AllWinner A20 is also pin-compatible with AllWinner A10, so existing products may soon be available for this low cost version. I still could not find any CPU clock details for either processor.

AllWinner A31 is clearly destined at higher products with both Android and Windows RT, whereas AllWinner A20 is a low cost version for Android tablets and set-top boxes.

Linux is not mentioned for any of sun6i processors, as AllWinner does not appear have Linux SDK, and Alejandro Mery – one of the main developers at sunxi-linux.org – said the community does not have any source for sun6i at the moment. Proper Linux support would be difficult for A31 due to the Power VR GPU, and it’s more likely work could be done on AllWinner A20, if GPL sources are made available.

Good start, bad paсe. Only linux support may save them.

Interesting that WinRT is mentioned, did they reveal something before they were supposed to as Microsoft has only certified something like only 3 or 4 SoC’s to run WinRT.

Hello CNX, “8 core Power VR SGX544 GPU” is depicted incorrectly
it should be “8 core of shader engine”, which is equal to dual core of sgx544 (mp2) or 1 single sgx544mp2

Sata support? And RGB video in the two models… no?

As can be seen from article, there’s no SATA interface: neither on A31, nor on A20. Good night, sweet Mele A1000 – no chance for reincarnation with dual or quad core CPU 🙁 🙁 🙁

512MB L2-Cache for AllWinner A20 seems a little bit much, doesn’t it?

This page [1] seems to suggest that the A20 has SATA, and the A31 does not have SATA, unless they are referring to SATA via USB.

Hi,

Looking on the A31 specification I wonder if it will be able to encode 4K video ? Or encoding profile will forbid that because it’s only 1080P? How it is with those profiles? They say only about ‘live’ encoding or generally that over 1080 resolution it will not encode ?

[…] Charbax is a CES 2013 now, and could ask a few questions about Rockchip upcoming SoC. RK3188 is a quad core Cortex A9 processor clocked up to 1.8-2.0 GHz, manufactured using 28nm HKMG process technology. The SoC features a quad-core Mali-400MP GPU,  1080p video decoder & encoder, and they can easily provide 4G/LTE support. RK3188 should be 20 to 30% faster than Nvidia Tegra 3, and have the same performance as Samsung Exynos 4412. Rockchip representative also stress that performance/cost ratio will be better than (Chinese) competitor basing their products on 4x Cortex A7. […]
