Hot Chips Microsoft today revealed a first look at the inside of its Holographic Processing Unit (HPU) chip used in its virtual reality HoloLens specs.
The secretive HPU is a custom-designed TSMC-fabricated 28nm coprocessor that has 24 Tensilica DSP cores arranged in 12 clusters. It has about 65 million logic gates, 8MB of SRAM, and a layer of 1GB of low-power DDR3 RAM on top, all in a 12mm-by-12mm BGA package. We understand it can perform a trillion calculations a second.
It handles all the environment sensing and other input and output necessary for the virtual-reality goggles. It aggregates data from sensors and processes the wearer's gesture movements, all in hardware so it's faster than the equivalent code running on a general purpose CPU. Each DSP core is given a particular task to focus on.
The unit sits alongside a 14nm Intel Atom x86 Cherry Trail system-on-chip, which has its own 1GB of RAM and runs Windows 10 and apps that take advantage of the immersive noggin-fitted display.
The details were revealed today at the Hot Chips conference in Cupertino, California. We grabbed a snap of the slides – apologies for the blurriness, we were sitting far back to get a decent Wi-Fi signal.

Thanks, Chuck.
10 to the -9 meters. 10^-6 meters is a micrometer (or micron).
Nanometre is one billionth of a metre.
About 36 billionth of an inch. :)
Nanometer, eh?
Well, I reckon that to be just about a hundredth of an RCH.
(Extremely Old School and seriously Non PC NavAir system of measure, also expressed as Not Even a Damn Skosh.)
“an RCH”
Now there’s a unit of measure I do recognize ;-)
“About 36 billionth of an inch. :)”
I figger that’s a skosh smaller than an RCH.
Zombie Apocalypse and SkyNet.
There is no future.
SkyNet.
Zombies.
wait until the CEO *forces* it to run windows, and it will slow down to the speed of a slug.
Microsoft screws up everything. “Secret Sauce” should be the software. But Msoft engineers can’t code their way out of a BSOD
