Amlogic (USA) Ltd., also known asAmlogic, Inc. (sometimes stylizedAMLogic) is afabless semiconductor company that was founded on March 14, 1995, and is headquartered in Mountain View, California. It predominantly focuses on designing and selling system-on-a-chip (SoC) solutions. Amlogic has offices worldwide including Mountain View (HQ), Bangalore, Seoul, Singapore, Tokyo, London, Milan, Munich, Japan, Taiwan, and Novi Sad, Serbia, and offices in Hong Kong and China.[3]
It developedVideo CD player chips and later chips forDVD players and other applications involvingMPEG2 decoding.[4] Am logic was involved in the creation of the HVD (High-Definition Versatile Disc) standard promoted in China as an alternative to DVD video disks used in DVD players.[5] The company was a player in the developing Chinese tablet processor market since 2010–2013.[6][7]
Amlogic is anARM licensee[8][9] and uses theARM architecture in the majority of its products as of 2014[update]. According to a joint press release with ARM in 2013, it was the first company to use ARM'sMali-450 GPU in a configuration with six cores or more.[10]
Amlogic AML8726-M – Legacy single coreARM Cortex A9-based SoC withARM Mali-400 GPU released in 2011, with a 16-bit DRAM interface and manufactured on a 65 nm process.[6][11]

Am logic MX (also known asAML8726-M6) – Dual-core ARM Cortex A9-based SoC withARM Mali-400 MP2 GPU, released in 2012 on a 40 nm process.[13][14]
Am logic M802 (originally called AML8726-M8) – Quad-coreARM Cortex A9-based SoC withARM Mali-450 MP6 GPU[10][15] running at 600 MHz.[16] Supports 4 GBDRAM and4K2K display output. 64-bit DRAM interface, manufactured on a 28 nm HPM process.[17]
Amlogic M801 – Similar to M802 but with DRAM limited to 2 GB and display output limited to1080p.[13][17]
Amlogic M805 – Quad-coreARM Cortex-A5-based SoC with Mali-450 MP2 GPU in a reduced-size 12 mm x 12 mm LFBGA package.[13][17]
The M801/802 uses a new version of ARM's Cortex-A9 core (A9r4) that theoretically allows for higher clock speeds and lower power consumption compared to older versions of the Cortex A9 core such as the A9r3 used inRockchip RK3188.[17]
Originally scheduled to be in production as early as the middle of 2013[18] in the form of the AML8726-M8, as of April 2014[update], only one tablet (Onda V975M)[19] has been announced using a chip from the M8 family.
A few manufacturers have shown Android TV boxes using the M802 (Shenzhen Tomato Technology,[15] Tronsmart,[20] Eny Technology[20] and GeniaTech[21]). It has been noted that some devices using the M802 may run hot and use a heatsink for cooling.[15] This is common among other popular OTT set top boxes such as the Amazon Fire TV which uses a metal shell to disperse heat, much like a heatsink would.[22]
Amlogic also offers SoC products (S802,S805, andS812) specifically targeting Android TV boxes and OTT set-top boxes (which are variations of similar SoCs in the M series targeting tablets).[23]

Amlogic S905Z – Similar to S905X (VP9 hardware decoding, HDR, 4K@60fps ...), but no more details known about it, used in the third generation Amazon Fire TV and the Fire TV Cube.
Amlogic S912 – Octa-coreARM Cortex-A53-based SoC (Big.LITTLE configuration 4x1.5 GHz and 4x1.0 GHz) with aMali-T820 MP3 GPU running at 600 MHz.[16]
Devices based on them are already in the market running Android 5.1 to 7.1, they are usually paired with 1 GB, 2 GB or 3 GB RAM, 8 GB to 64 GB flash memory, they have features such as a Gigabit Lan and Dual band 2.4G/5G A/C WiFi.
S905X was scheduled to be released in Q1 2016 while S905D and S912 were scheduled for Q2 2016. All three of the SoCs haveAndroidMarshmallow andBuildroot Linux SDKs released.
At IBC 2018 Amlogic showed to the public for the first time their second generation SoCs for media players on reference boards running Android TV 9.[28]
Amlogic S905X2 – Quad-coreARM Cortex-A53-based SoC with aMali-G31 MP2 "Dvalin" GPU and adds to the first generation SoCs support to HDMI 2.1 at 4k60 and to the HDR formats ofDolby Vision and TCH Prime.[29]
Amlogic S905Y2 – Silmilar to the S905X2, built for smaller HDMI dongles and because of that it loses some features like Ethernet, DVP (Digital Video Port) interface,CVBS (Composite video).[29]

In the market for SoCs targeting Chinese tablet manufacturers and manufacturers of Android media players, TV boxes and media dongles, it faces competition primarily fromRockchip,Allwinner Technology,Actions Semiconductor,MediaTek,Intel andRealtek.[58][59][60][61] Amlogic was reported to be fourth largest application processor supplier for Chinese tablets in 2012.[7] For Q2 2014, Amlogic was reported to be the fifth largest supplier, afterRockchip,MediaTek,Allwinner andActions Semiconductor.[62]Chinese SoC suppliers that do not havecellular baseband technology are at a disadvantage compared to companies such as MediaTek that also supply thesmartphone market as white-box tablet makers increasingly add phone functionality to their products.[63]
In 2011, the AML8726-M was selected as one of the "hottest" processors byEE Times China,[6] while in 2012, the AML8726-MX wonEE Times-China's Processor of the Year award.[64]
Amlogic maintains a website[65] dedicated to providing source code for theLinux kernel andAndroid SDK supporting Amlogic chips and reference designs. The Linux kernel source code is freely available, and has recently (as of April 2014) been updated to support certain chips in the M8 family as well as the older MX family, with Android versions up to 4.4 (KitKat) being supported (based on Linux kernel version 3.10.x). However, the Android SDK requires a NDA and is only available to business partners. The source code includes Linux kernel 3.10.10,U-Boot,Realtek andBroadcomWi-Fi drivers,NAND drivers, "TVIN" drivers, and kernel space GPU drivers for theMali-400/450GPU.[66] XBMC/Kodi Amlogic S805 / M805 / S806 / M806 / S812 Android video decoding compatibility list:Android hardware - Official Kodi Wiki
