It would be interesting to see if someone can break down processors from Samsung or Qualcomm ("Snapdragon") for us.

This might be interesting. It is AMDs heterogeneous architecture.

VP7

Qualcomm Snapdragon essentially consists of (summary based on Snapdragon 800*)

  1. CPU : Krait which is an quad core ARM Cortex Core-A* derivative

  2. GPU : Adreno an on chip GPU based on the assets acquired from AMD. (although I believe it is not readily programmable using OpenCL)

  3. DSP : Hexagon, a high performing DSP which makes qualcomm SoCs stand out in the crowd. (Probably inspired by Texas Instrument's DSPs on OMAP* SoCs). [VLIW with hardware multithreading] (https://developer.qualcomm.com/mobile-development/maximize-hardware/multimedia-optimization-hexagon-sdk/hexagon-dsp-processor)

  4. On Chip Modem/ Wireless Hardware: Gobi/ X7/ X11

  5. Codecs: ASIC for video encoding and decoding. (typically H264/AVC). I believe the audio codecs are implemented in software and runs on hexagon.

  6. ISP: They have a dual ISP (ASIC)

  7. ASIC to drive Display/ LCD which implicitly supports Miracast stack(a wifi-display specification)

It looks like they also have a module in hardware to deal with GNSS.

Can some one give a shot at breaking down Exynos into a few point?
