Revision 0.7
AMLOGIC, Inc. Proprietary 4/32
1. General Description
S805 is an advanced application processor designed for Set Top Box(STB) and high-end media player applications. It integrates
a powerful CPU/GPU subsystem, and a secured FHD video CODEC engine with all major peripherals to form the ultimate low
power multimedia AP.
The main system CPU is a quad-core ARM Cortex-A5 CPU with 32KB L1 instruction and 32KB data cache for each core and a
large 512KB L2 unified cache to improve system performance. In addition, the Cortex-A5 CPU includes the NEON SIMD co-
processor to improve software media processing capability. The quad core ARM Cortex-A5 CPU can run up to 1.5GHz and has
a wide bus connecting to the memory sub-system.
The graphic subsystem consists of four graphic engines and a flexible video/graphic output pipeline. The four core ARM Mali-
450 GPU including dual geometry processors (GP) and dual pixel processors (PP) handles all the 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. The video output pipeline can perform advanced image correction and enhancements. Together, the CPU and GPU
handle all operating system, networking, user-interface and gaming related tasks.
One additional processor offload the Cortex-A5 CPUs by handling all the video CODEC processing – Amlogic Video Engine (AVE)
including dedicated hardware video decoder and encoder. AVE is capable of decoding 1080p resolution video with complete
Trusted Video Path (TVP) for secure applications and supports full formats including MVC, MPEG-1/2/4, VC-1/WMV, AVS,
RealVideo, MJPEG streams, H.264, H265 and also JPEG pictures with no size limitation. The independent encoder is able to
encode in JPEG and H.264 up to 1080p at 30fps.
S805 integrates all standard audio/video input/output interfaces including an HDMI1.4b transmitter with 3D support, CEC and
HDCP, a CVBS output, I2S and SPDIF digital audio input/output interfaces and a PCM audio interface.
S805 also integrates a set of functional blocks for digital TV broadcasting streams. The built-in three demux can process the TV
streams from the serial transport stream input interface, which can connect to external tuner/demodulator. An ISO7816 smart
card interface and a crypto-processor built in to help handling encrypted traffic and media streams.
The processor has rich advanced network and peripheral interfaces, including a Gigabit Ethernet MAC with RMII/RGMII
interface, dual USB 2.0 high-speed ports (one OTG and one HOST), three SDIOs with multi-standard memory card controller,
five UART interfaces, five I2C interfaces, one high-speed SPI interface and five PWMs.
Standard development environment utilizing GNU/GCC Android tool chain is supported. Please contact your AMLOGIC sales
representative for more information.
