S912 is an advanced application processor designed for high performance 4k OTT/IP Set Top Box (STB) and gaming box applications. It integrates a powerful CPU/GPU subsystem, a secured 4K video CODEC engine and a best-in-class HDR image processing pipeline with all major peripherals to form the ultimate low power multimedia AP. The main system CPU is an octa-core ARM Cortex-A53 CPU grouped into two CPU clusters with large unified L2 cache. Each cluster, which consists of four Cortex-A53 cores with L1 instruction/data cache for each core, is controlled by DVFS software and can be independently clocked up to 2GHz. In addition, the Cortex-A53 cores include the NEON SIMD co-processor and I/D-cache to improve the overall system performance.

The graphic subsystem consists of two graphic engines and a flexible video/graphic output pipeline. The ARM Mali-T820MP3 GPU 3 shader engines, with 1 Arithmetic Unit (ALU ), 1 Load/Store Pipeline and 1 Texture Pipeline contained in each shader, handles all the OpenGL® ES 3.1/2.0/1.1, DirectX®11 FL9_3, OpenCL™ 1.1/1.2 full profile and Android™ RenderScript; while the 2.5D graphics processor handles additional scaling, alpha, rotation and color space conversion operations. Together, the CPU and GPU handle all operating system, networking, user-interface and gaming related tasks. The video output pipeline includes advanced HDR10, HLG and Dolby Vision HDR processing, REC709/BT2020 processing, motion adaptive edge enhancing de-interlacing, flexible programmable scalar, and many picture enhancement filters before passing the enhanced image to the video output ports.

Amlogic Video Engine (AVE-10) offloads the Cortex-A53 CPUs from all video CODEC processing. It includes dedicated hardware video decoder and encoder. AVE-10 is capable of decoding 4K2K resolution video at 60fps within Trusted Video Path (TVP) for secured DRM applications. It supports all major video formats including MVC, MPEG-1/2/4, VC-1/WMV, AVS, AVS+, RealVideo, MJPEG streams, H.264, H265-10, VP9-10 and also JPEG. The independent encoder can concurrently encode in JPEG, and H.264 up to 1080p at 60fps.

S912 integrates all standard audio/video input/output interfaces including a HDMI2.0a transmitter with 3D, HDR, CEC and HDCP 2.2 support, stereo audio DAC outputs, a CVBS output, PCM, I2S and SPDIF digital audio input/output interfaces, stereo PDM digital MIC inputs and DVP camera interface. S912 also integrates a set of functional blocks for digital TV broadcasting streams. The built-in two demux can process the TV streams from the serial and parallel transport stream input interface, which can connect to external tuner/demodulator and CI+ module. An ISO7816 smart card interface and a crypto-processor are built in to help handling encrypted traffic and media streams.

The processor has rich advanced network and peripheral interfaces, including a Gigabits Ethernet MAC with RGMII interface, 10/100M Ethernet PHY, triple USB 2.0 high-speed ports (one OTG and two HOSTs) and multiple SDIO/SD card controllers, UART, I2C, highspeed SPI and PWMs. Standard development environment utilizing GNU/GCC Android tool chain is supported.
