Amlogic S905D3芯片简介，可内置独立NPU,专为人工智能和物联网场景设计的通用型SoC。
S905D3 is an advanced application processor designed for hybrid OTT/IP Set Top Box (STB) andhigh-end media box applications. It integrates a powerful CPU/GPU subsystem, a powerful NPU(Neural Network Processing Unit)Optional,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-A55 CPU with unified L3 cache to improve systemperformance. In addition, the Cortex-A55 CPU includes the NEON SIMD co-processor to improve software media processing capability.
The graphic subsystem consists of two graphic engines and a flexible video/graphic output pipeline.The ARM G31 MP2 GPU handles all OpenGL ES 3.2 Vulkan 1.0 and OpenCL 2.0 graphic 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 Dolby Visionoptional, HDR10+, HDR10,
HLG and PRIME HDR processing, BT.709/BT.2020/BT.2100 processing, motion adaptive edge enhancing de-interlacing, flexible programmable scalar, and many picture enhancement filters beforepassing the enhanced image to the video output ports.
Amlogic Video Engine (AVE-10) off-loads the Cortex-A55 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 +, AVS2 RealVideo, MJPEG streams,H.264, H265-10, VP9 and also JPEG pictures with no size limitation. The independent encoder is able to encode in JPEG or H.265/H.264 up to 1080p at 60fps.
S905D3 integrates all standard audio/video input/output interfaces including a HDMI2.1 transmitter with 3D, Dynamic HDR(w/EMP), CEC and HDCP2.2, ALLM(Auto Low Latency Mode) support,stereo audio DAC, a CVBS output,4-lane MIPI DSI interface,2–lane MIPI CSI interface, multiple TDM, PCM, I2S and SPDIF digital audio input/output interfaces, and 8 channel far-field PDM digital microphone (DMIC) inputs. It also has build-in Voice Activity Detection(VAD)module for ultra-low power operations during system standby.
S905D3 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 paralleltransport stream input interface, which can connect to external tuner/demodulator. The processor has rich advanced network and peripheral interfaces, including a 10/100/1000M Ethernet MAC with RGMII, 10/100M Ethernet PHY,a set of multi-PHY for USB2, USB3 and PCIe,and multiple SDIO/SD card controllers, UART, I2C, high-speed SPI and PWMs. Standard development environment utilizing GNU/GCC Android tool chain is supported.
