Summary of LINUX-POWERED DEVELOPMENT KIT IS THE FIRST TO HAVE AN AI-ENABLED CORTEX-A7 CAMERA SOC
Sochip and Allwinner released a V831 development board featuring the Allwinner V831 IP camera SoC, the first Allwinner camera processor with an integrated NPU. The V831 is a single-core Cortex-A7 (up to 800 MHz) supporting H.265 up to 1080p@330fps, a 0.2 TOPS NPU for facial recognition/detection, advanced ISP features, EIS, audio codec, crypto engine, and multiple interfaces for camera, audio, storage, and I/O.
Parts used in the V831 development board:
- Allwinner V831 IP camera SoC (single-core ARM Cortex-A7, up to 800 MHz, 0.2 TOPS NPU)
- 64MB DDR2
- External eMMC 5.0 interface
- NOR flash
- SPI NAND flash
- 2-lane MIPI-CSI interface
- RGB output (up to 320 x 240 @ 60fps)
- 10/100 Mbps Ethernet port
- TDM interface for external audio codec
- 20-bit audio codec (audio input and output)
- Up to 54 GPIOs
- USB 2.0 OTG
- 4x UART
- I2S (listed as 12S in article)
- SPI
- RTC (1x)
- Power supply: Core 0.9V, I/O 3.3V
Sochip partners with Allwinner to launch a new V831 development board that showcases an Allwinner V831 IP Camera SoC, the very first to include an AI chip.
Allwinner has released quite a number of camera processors in the past, the V3, V316, S3, and many more, but none of them ever came with a built-in NPU aka AI accelerator. Things, however, have taken a new turn now as an Allwinner V831 AI full HD Camera SoC with NPU aka AI accelerator is used to power Sochip’s linux-driven V831 development board.
Allwinner’s high performance, low powered IP camera SoC integrates single-core ARM Cortex-A7 topping out at 800MHz frequency and supports H.265 video encoding of multiple streams up to 1080p @ 330fps. The SoC also features a 0.2 TOPS NPU for facial recognition and detection, Electronic image stabilization engine support, the latest generation of ISP image processor that supports up to 2688 x 2688 pixels, wide-angle distortion correction, PTZ calibration, SmartColor support for excellent display and other image correction algorithms that make it easy to achieve professional image effects.
It is further equipped with 20-bit audio codec for audio input and output, crypto engine, 64MB DDR2, external eMMC 5.0 interface, NOR and SPI NAND flash.
Other features include:
- 2-lane MIPI-CSI interface
- RGB output up to 320 x 240 @ 60fps
- 10/100 Mbps Ethernet port
- TDM interface for connecting to external audio codec
- Up to 54 GPIOs
- USB 2.0 OTG
- 4x UART
- 12S
- SPI
- 1x RTC
- Dimension: 9 x 9 mm
- Supply voltage: Core: 0.9V, I/O: 3.3V
