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. 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.

Microsoft today revealed HoloLens 2 at MWC 2019 in Barcelona. The headset features a laser-scanning display which brings a field of view that's more than 2x the original HoloLens and 47 pixels per degree.
HoloLens visionary Alex Kipman took to the stage in Barcelona to introduce HoloLens 2 which addresses many of the key criticisms of the original headset: field of view, comfort, and hand-tracking.
Kipman says that HoloLens 2 "more than doubles" the field of view of the original HoloLens, though hasn't yet specified exactly what the field of view is. The original HoloLens field of view was around 35 degrees, so HoloLens 2 is expected to be around 70 degrees.
[...] HoloLens 2 is also designed to be more comfortable, with much of the headset's bulk balanced in the back of the headset. Kipman said HoloLens 2 "more than triples the comfort" over the original HoloLens... though the exact weight, and how they came to that specific figure, is unclear. Still, the front portion of the headset is said to be made entirely from carbon fiber to cut down on weight and offers a convenient flip-up visor.
HoloLens 2 also brings hand-tracking which goes much further than the coarse gesture control in the original headset. Now with full hand-tracking, users can interact much more directly with applications by touching, poking, and sliding controls directly rather than using abstract gestures.
