AMLOGIC S905X is an advanced application processor designed for OTT/IP Set an advanced application processor designed for OTT/IP Set Top Box (STB) and high-end media 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 a quad-core ARM Cortex-A53 CPU with L1 instruction/data cache for each core and a large unified L2 cache to improve system performance. In addition, the Cortex-A53 CPU includes the NEON SIMD co-processor to improve software media processing capability. The quad-core ARM Cortex-A53 CPU can be overdriven to 2GHz and has a wide bus connecting to the memory sub-system.

The graphic subsystem consists of two graphic engines and a flexible video/graphic output pipeline. The five core ARM Mali-450 GPU including dual geometry processors (GP) and triple pixel processors (PP).The multi-core GPU processor handles all OpenGL ES 1.1/2.0 and OpenVG graphics programs, 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 and HLG 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 4Kx2K resolution video at 60fps with complete Trusted Video Path (TVP) for secure applications and supports full formats including MVC, MPEG-1/2/4, VC-1/WMV, AVS, AVS+, RealVideo, MJPEG streams, H.264, H265-10, VP9-10 and also JPEG pictures with no size limitation. The independent encoder is able to encode in JPEG or H.264 up to 1080p at 60fps.

Amlogic S905X 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, a CVBS output, PCM, I2S and SPDIF digital audio input/output interfaces, and a stereo PDM digital MIC inputs.

The processor has rich advanced network and peripheral interfaces, including a 10/100M Ethernet MAC with FE PHY interface, dual USB 2.0 high-speed ports (one OTG and one HOST) and multiple SDIO/SD card controllers, UART, I2C, high-speed SPI and PWMs.

Standard development environment utilizing GNU/GCC Android tool chain is supported. The Amlogic S905X SoC is a good solution for Android TV Box.
