The parts in bold are likely supported by the Launch XB1 but have not been firmware updated yet.....they are the
ARM block accelerators that will be used by OpenVX which AMD just released version .9 for their APUs and dGPUs which are also used by UHD DRM and Player.
PS4 and XB1 are UHD Capable
Launch (2013) consoles are UHD Capable and will be firmware updated .........(
ARM TEE bus with Xtensa accelerators for PS4 in Southbridge and XB1 in the APU)
BDXL drives with 2010 specs can read UHD disks, BD-ROM Blu-ray drives are firmware updateable to read UHD Disks. (AACS 2 and BD+ still needed and they run in the TEE along with the Player and HEVC profile 10 codec).
AMD just released OpenVX beta (.9) for AMD APUs and dGPUs This is vision processing using Xtensa accelerators and OpenCV/OpenCL/GPU Compute.
Prior to OpenVX, everything uses OpenCV which uses GPU compute. With OpenVX properly supported by the vendor, Accelerators are added (Xtensa processors) and vision processing becomes more efficient.
Sony and Microsoft should be releasing OpenVX APIs for the PS4 and XB1. OpenVX is vision processing released by Khronos October 2014 and updated April 2016 to version 1.1.
Open VX extensions for HTML and tiling beginning of 2015. The description mentions Tiling extension deals with the CPU only. Micorosoft and Sony must write the extensions to use the Xtensa accelerators on the same ARM bus the TEE uses. The Xtensa accelerator is also used for the Codec which must be run in the TEE protected mode while the OpenVX can be run on the same bus without Trustzone protection.
Note: I in error assumed OpenVX would be supported by the PS4 soon after the October 2014 Khronos release of OpenVX 1.0. I should have understood that Sony would only release OpenVX when Game developers could use it on other Platforms (PC and XB1). OpenVX will be used by VR later this year so this release is timely.
OPENVX THE NEW KHRONOS API FOR COMPUTER VISION AND AR
=> Warping the video out for VR goggles, UHD Blu-ray digital bridge video conversion, VR.....
Edit: The Launch XB1 should get a bump in performance if AA is handled by the Accelerators rather than the GPU. This would require a minor rewrite and recompile of the XB1 launch games. Upscaling to 4k should also be handled by the Xtensa accelerators.
