HoloLens secrets revealed: Microsoft details its 24-core 'holographic processor'

The HoloLens’ HPU is a custom 28nm coprocessor designed by TSMC

The chip packs 24 Tensilica digital signal processor (DSP) cores. As opposed to more general-purpose CPU cores, DSPs are a specialized technology designed for rapidly processing data flowing in from the world—a no doubt invaluable asset while rendering augmented reality environments in real time. Microsoft’s HPU also contains roughly 65 million logic gates, 8MB of SDRAM, and 1GB of traditional DDR3 RAM. It draws less than 10W of power, and features PCIe and standard serial interfaces.

The HPU's dedicated hardware is up to 200 times faster than performing the same calculations via software on the less-specialized 14nm Intel Cherry Trail CPU. The HPU can perform roughly 1 trillion calculations per second, and the data it passes to the CPU requires little additional processing.

    Is Microsoft designing their own silicon these days ? 0.o

    Certainly sounds like they've got a solid headstart in AR tech here. I wonder if Hololens will turn out to be one of MS's major moneyspinners in the future ?

    Yeah I am really curious about this tech.

    This is where the future of AR & VR is!  Not in pokemon.

    This is something interesting.

    Imagine of MS does a deal with Pokemon Go on Hololens? Or even similar games?

    CASH! :proud:

    Wait, what?  Designed by TSMC, not merely fabricated by TSMC?  Since when did TSMC design processors?

    Since Microsoft built a machine to talk to god in order to make a device that defies the laws of physics.

    Hololens itself? Probably not, no. Later tech derived from it has a good chance though.

    Microsoft makes a lot of money from patents. Every cellphone sold sends their cut to Microsoft. Their OS business and office business is not doing as well because people are getting used to free options. So I expect Microsoft to gladly let others use the technology in HoloLens on their own hardware. Then make royalties.
