Amlogic is Working on S905 and S912 64-bit ARM Cortex A53 Processors

The relatively popular Amlogic S805 and S812 Cortex A9 processors are soon going to be joined by Amlogic S905 and S912 processors, both featuring ARM Cortex A53 64-bit cores, with the former destined to entry-level media players, and the latter for higher end devices including 4K60 / HDMI 2.0 support, as well as H.265 and AVS+ hardware video codecs. The company is now showcasing its new processors at China Content Broadcasting Network Exhibition (CCBN) 2015 in Beijing until March 28.

Amlogic_S912Details are sparse, but we still know a few features for the new Amlogic 64-bit ARM processors:

  • CPU – Quad Core ARM Cortex A53 CPU @ 2.0 GHz with 512KB unified cache.
  • GPU –
    • S905: 5 core Mali-450MP to 750MHz with OpenGL ES 11./2.0 and OpenVG 1.1 support, unnamed 2.5D GPU
    • S912: TBD
  • Video – [email protected] Hz video decoding 10-bit HEVC and AVS+ codec support; H.264 up to 4K 30 Hz; 1080p60 H.264 encoding
  • Video Output – HDMI 2.0 + HDCP 2.2
  • Audio – DTS & Dolby support
  • Crypto engine for AES-128/192/256, SHA-1/SHA-2 engine
  • TrustZone support
  • Manufacturing Process – 28 nm

4K might only be supported in S912, just like S805 supports 1080p and S812 is capable of handling 4K video decoding and output. Both processors support 4K video output and deocding. Linux and Android 5.1 SDK will be released for both processors. S905 processor will allegedly be power efficient enough to make it into HDMI dongles too.

Mass production of S905 devices should start in Q2 2015, while high-performance media players based on S912 should become available in Q3 2015.

Information about the S905 and S912 is only available on Chinese websites such as DVBCN, which interviewed Gordon Pan, VP at Amlogic.
