Most SoCs have a very limited amount of internal SDRAM just enough to load the bootROM code, but a few integrated a few MB of RAM on-chip such as Renesas RZ/A1H with 10MB on-chip DRAM, in order to reduce costs for some applications that may not require external RAM. Allwinner V3s, designed for dual camera solutions, appeared to be such an SoC with 64MB (512Mbit) on-chip DDR2 RAM, but the block diagram seems to imply it is a System-in-Package (SiP) instead. Nevertheless you still get a single chip with an ARM Cortex A7 processor, two ISPs, a video engine, 64MB RAM, and more. Allwinner V3s main features & specifications: CPU – ARM Cortex-A7 @ up to 1.2 GHz Memory – Integrated 64MB DDR2 DRAM Storage I/F – SD 2.0, eMMC 4.41, SPI NAND flash, SPI NOR flash Audio Codec – 92dB audio codec supporting 2x ADC channels and 2x DAC […]
$64 Allwinner V3 Action Cameras Support 4K Video Recording (or Not?)
An “Allwinner V3 4K Ultra HD DV Sport Camera” just appeared in GeekBuying product feed which the company sells for $84.39, and searching for alternative sellers led me to Soocoo F60 4K action camera sold for $63.34 on GearBest. Both cameras look the same, and the price appears amazing cheap as 4K cameras such as GoPro Hero4 or Sony X1000V normally sell for $500 and more. But one of the tricks is that both “4K” cameras are likely based on Sunchip 4K camera design, which does support 4K video recording, but only at 15 fps. Soocoo F60 camera specifications: SoC – Allwinner V3 ARM Cortex A7 processor @ 1.2GHz System Memory – N/A Storage – micro SD card up to 64GB Display – 2″ LCD Camera OmniVision OV4689 image sensor (4MP according to sensor page, but 16MP on camera description, probably achieved with extrapolation). 170-degree wide angle Recording time up […]
Allwinner V3 SoC Targets 1080p60 Action Cameras, Supports Linux or Camdroid OS
I’ve previously written about Allwinner V10 and V15 SoC for video applications such as cameras, digital video recorder, and so on. So far, I’ve not found devices based on these, but Allwinner already announced another V-series processor with Allwinner V3 designed for Action camera recording up to 1080p resolution at 70 frames per second. Key specifications are listed below: CPU – ARM Cortex-A7 @1.2GHz Memory 16-bit DDR3/LPDDR3/DDR3L SDRAM controller, up to 1333Mbps 16-bit DDR2 up to 800Mbps, 16-bit LPDDR2 up to 1066Mbps up to 2GB RAM Video / Picture Up to 1080p@60fps or 2-channel 1080p@30fps H.264 video encoding 8M JPEG encoding H.264 1080p@60fps decoding, MJPEG 1080@30fps decoding Integrated ISP up to 8M pixels (HawkView ISP) 2 channel outputs for display and encoding respectively Supports various input and output formats Supports AE/AF/AWB Saturation adjustment, 2D/3D noise reduction, defect pixel correction, and distortion correction Audio Codec Integrated 92dB audio codec 2x ADC […]
Allwinner CedarX Media Codec Library GPL/LGPL Compliance Update
Last month, I wrote about potential open source licenses and VP6 copyright infringement by Allwinner with their CedarX media codec library, and then since there’s been a few developments. First, Allwinner sent me an email saying they’ve now updated Cedarx library and referring my previous article. Here’s an extract: Here, I have some update of the Allwinner’s open-source status. We have done a lot of discussion with the developers from the linux-sunxi communication about the software license of CedarX. For each question or requirement asked by the developers, Allwinner has identify and try to give the best solution. Now, we believe Allwinner’s CedarX license is fully compliant and resolves concerns from the community. And you can take the announcement https://www.mail-archive.com/linux-sunxi@googlegroups.com/msg10597.html as a reference. Allwinner is always supporting the open-source, and try to do better and better. You can see some update on the github https://github.com/allwinner-zh, and some feedback from developers: […]
