Technical content

R818 is a highly-integrated application processor designed for smart speaker with screen. It integrates quad-core 64-bit Cortex TM-A53 CPU and Imagination PowerVR GE8300 GPU to ensure response rapidity and running smoothness for daily application, such as on-line video, web browsing, and so on. It also integrates two ADCs for dual-mic voice solutions, DMIC and I2S for multi-mic solutions, two DACs for stereo audio speaker. Quad-Core Smart Device Processor The Highly competitive speaker with screen Analog audio interfaces support two ADCs, two DACs, and one stereo headphone. Digital audio interfaces support I2S, DMIC, and OWA. With the rich audio interfaces, R818 can meet the requirements of mainstream audio recognition solutions. Also, with the companion chip AC107, R818 supports up to 8 mic array to meet the needs of far field voice recognition solutions. Rich Audio Interfaces R818 integrates two MIPI CSI interfaces and one 13M ISP , which can input/process the data of two camera sensors at the same time and meet the requirements of binocular depth of field, binocular face recognition and other visual AI schemes, such as ToF and 3D-Structured Light. Dual Cameras R818 supports mainstream video decoding such as H.265 (maximum performance up to 4K@30fps), H.264 video encoding up to 1080p@60fps, display output up to FHD 1080p@60fps, and Allwinner SmartColor 2.0 display enhancement technology to provide excellent video experience for users. High Video Performance R818 adopts quad-core 64-bit Cortex TM-A53 CPU up to 1.5GHz, which has a more powerful performance to ensure response rapidity of daily application than A35 CPU. The CoolFlex low-power design architecture and dynamic power consumption management technology ensure excellent energy efficiency ratio for most scenes. The integrated Imagination PowerVR GE8300 GPU can easily meet the computing requirements of various mainstream graphics. Powerful Operation Capacity
