Amlogic (sometimes spelled AMLogic) is an American technology company that was founded in the US as Amlogic Inc.  and is predominantly focused on designing and selling SoC (System on 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 2014 are entertainment devices such as Android-based TV and IPTV/OTT set-top boxes, media dongles, smart TVs and tablets. It has offices in Shanghai, Beijing, Shenzhen, Taipei, Hong Kong, and Santa Clara, California.

Amlogic is an ARM license 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.

First 64-bit Amlogic Products lineup.

On August 28, 2016, all members of the S9 family were reported to be internally limited to 1.5 GHz instead of the advertised 2.0 GHz clock rate. As of that date, it was not clear if the limitation was due to hardware, firmware or software issues.

• S905 – Quad-core ARM Cortex-A53 (up to 2.0 GHz) with a Mali 450MP3 GPU, supports hardware decoding up to 4K@60fps for multiple formats including H.265 10-bit, H.264, AVS+.
• S905X – Similar to S905 except it supports up to 4K@60fps VP9 profile-2 hardware decoding, HDR, HDMI 2.0a and having a built-in DAC.
• S905L – Similar to S905X except it supports HDMI 2.0b but lack VP9 decoding, camera interface and TS inputs.
• S905D – Similar to S905X except it supports DVB interface.
• S912 – Octo-core ARM Cortex-A53 (Big.LITTLE configuration 4×2.0 GHz and 4×1.0 GHz) with a Mali T820 MP3 GPU.

S9**(*)-H models include Dolby/DTS licenses.

Devices based on them are already in the market running Android 5.1 or 6.0, they are usually paired with 1GB, 2GB or 3GB RAM, 8GB to 64GB Flash Mem, 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 SoCs have Android Marshmallow and Buildroot Linux SDKs released.
