Amlogic Inc. (sometimes stylized AMLogic) is a fabless semiconductor company that was founded on March 14, 1995, in Santa Clara, California and is predominantly focused on designing and selling system on a chip integrated circuits. Like most fabless companies in the industry, the company outsources the actual manufacturing of its chips to third-party independent chip manufacturers such as TSMC. Its main target applications as of 2021 are entertainment devices such as Android TV-based devices and IPTV/OTT set-top boxes, media dongles, smart TVs and tablets. It has offices in Shanghai, Shenzhen, Beijing, Xi'an, Chengdu, Hefei, Nanjing, Qingdao, Taipei, Hong Kong, Seoul, Mumbai, London, Munich, Indianapolis, Milan, Novi Sad and Santa Clara, California.
It developed Video CD player chips and later chips for DVD players and other applications involving MPEG2 decoding. 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. The company was a player in the developing Chinese tablet processor market since 2010–2013.
Am logic is an ARM licensee and uses the ARM architecture in the majority of its products as of 2014. According to a joint press release with ARM in 2013, it was the first company to use ARM's Mali-450 GPU in a configuration with six cores or more.
Products
= Tablet computer SoC
=AML8726 family
Amlogic AML8726-M – Legacy single core ARM Cortex A9-based SoC with ARM Mali-400 GPU released in 2011, with a 16-bit DRAM interface and manufactured on a 65 nm process.
Amlogic AML8726-M3 – Legacy single-core ARM Cortex A9-based SoC with ARM Mali-400 GPU, released in 2012, with a 16-bit DRAM interface and manufactured on a 45 nm process.
Am logic MX (also known as AML8726-M6) – Dual-core ARM Cortex A9-based SoC with ARM Mali-400 MP2 GPU, released in 2012 on a 40 nm process.
M8 family (announced 2013)
Am logic M802 (originally called AML8726-M8) – Quad-core ARM Cortex A9-based SoC with ARM Mali-450 MP6 GPU running at 600 MHz. Supports 4 GB DRAM and 4K2K display output. 64-bit DRAM interface, manufactured on a 28 nm HPM process.
Amlogic M801 – Similar to M802 but with DRAM limited to 2 GB and display output limited to 1080p.
Amlogic M805 – Quad-core ARM Cortex-A5-based SoC with Mali-450 MP2 GPU in a reduced-size 12 mm x 12 mm LFBGA package.
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 in Rockchip RK3188.
Originally scheduled to be in production as early as the middle of 2013 in the form of the AML8726-M8, as of April 2014, only one tablet (Onda V975M) has been announced using a chip from the M8 family.
A few manufacturers have shown Android TV boxes using the M802 (Shenzhen Tomato Technology, Tronsmart, Eny Technology and GeniaTech). It has been noted that some devices using the M802 may run hot and use a heatsink for cooling. 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.

Markets and sales
Amlogic does not publish sales or financial information on its website.
The company is listed as a client of several venture capital firms.
In the market for SoCs targeting Chinese tablet manufacturers and manufacturers of Android media players, TV boxes and media dongles, it faces competition primarily from Rockchip, Allwinner Technology, Actions Semiconductor, MediaTek, Intel and Realtek. Amlogic was reported to be fourth largest application processor supplier for Chinese tablets in 2012. For Q2 2014, Amlogic was reported to be the fifth largest supplier, after Rockchip, MediaTek, Allwinner and Actions Semiconductor.
Chinese SoC suppliers that do not have cellular baseband technology are at a disadvantage compared to companies such as MediaTek that also supply the smartphone market as white-box tablet makers increasingly add phone functionality to their products.
In 2011, the AML8726-M was selected as one of the "hottest" processors by EE Times China, while in 2012, the AML8726-MX won EE Times-China's Processor of the Year award.
Open source commitment
Amlogic maintains a website dedicated to providing source code for the Linux kernel and Android 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 and Broadcom Wi-Fi drivers, NAND drivers, "TVIN" drivers, and kernel space GPU drivers for the Mali-400/450 GPU.

However an effort to push Linux upstream support for the GX ARM64 lineup is ongoing on Linux for Amlogic — Linux for Amlogic Meson https://gitlab.com/pages/sphinx documentation. Currently only the AML8726MX, S802, S805 and S905 SoC are booting headless on Linux 4.8. But S905X, S905D and S912 Headless support is expected for Linux 4.10.
