A31 Hummingbird Development System based on Allwinner quad core A31 processor. A31 processor enriched with interfaces, including CVBS input and output, HDMI, VGA, MIPI/CSI, dual-channel LVDS, dual-channel RGB/CPU LCD,SATA,USB, SPI and GMAC.

Specifications Of A31 SoC:

A31 processor applies the quad-core ARM Cortex-A7 CPU structure, including all characteristic of Cortex-A15, and the A31 processor is the most energy saving processor in present ARM platform. Equipped with PowerVR™ SGX544MP2 GPU, A31 not only improves the system performance, but also satisfy the excellent game compatibility. In addition, A31 supports 3840x1080 video encoding and decoding.

Highlights Of A31

The main specifications of A31 quad-core mobile application processor are as following:

• Quad-core Cortex™-A7 ARM CPU structure
• Equipped with a Power VR SGX544MP2 GPU and has eight logic cores.
• Support dual-channel DDR and NAND Flash.
• Integrated HawkView camera ISP, support HD image processing and fast image capture.
• Integrated MIPI DSI/MIPI CSI module
• Integrated audio codec module

Compare with Cortex-A8, the performance Cortex-A7 has increased up to 50% while the dimension is one-fifth of the A8, and its efficiency is five times of the A8. The A31 dual-core mobile application processor combines with the ARM high performance. It is not only satisfy website surfers, but those who streams video and play in 2D/3D games, at the same time it minimizes the power consumption.

Games

Game rendering quality is becoming better in the quad-core A31 SoC, the generated video output is more accurate with less lags. Meanwhile, A31 uses the same series GPU as Apple which is enhance game compatibility with more than 95% of applications on the market.

Vedio

A31 reflects the fourth-generation video processing technology of Allwinner, it supports 4Kx2K video decoding, Blue-ray 3D @ 30fps and four-way 720P video codecs simultaneously. The 4K player supports multiple video display outputs; video engine interface is more open, with supporting the OpenMax standarts.

Web surfing

Web browser supports playback video with hardware acceleration, web page can be loaded for less than 5 seconds with website optimizations and with sufficient Internet bandwith.

Camera

A31 integrated 4 lanes MIPI CSI interfaces, support up to 12 million pixel camera and 1080P @ 60fps video recording. You can use it in processor demanding applications such as face detection, panorama shot, auto focus, 3D camera and others.

Low power consumption

A31 power consumption was decreased by more than 20%, It supports up to 30 days of standby working from batteries, over 100 hours of music playback, over 10 hours of video playback and more than 8 hours of web browsing.

Storage

A31 supports 16-bit dual-channel NAND, read and write speed wasincreased up to 100%in comparison with A20.

Display

A31 SoC supports eDP or 4 lanes MIPI interface in order to use with retina displayswith resolution up to 2048x1536.

Tools

Allwinner-Technology launched two upgraded version of the firmware tools: Phoenixsuit and OTA, it supports firmware modification tool such as DragonFace, and mass production testing tools - DragonFire, DragonBoard and DDRTest.
