Microsoft releases details on their HPU (Holographic Processing Unit), their custom chip for processing sensor data in their HoloLens headset.
Microsoft's HoloLens secret sauce: A 28nm 24-core DSP custom brain built by TSMC
Hot Chips Microsoft today revealed a first look at the inside of its Holographic Processing Unit chip used in its virtual reality HoloLens specs. The 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 1GB of low-power DDR3 RAM, all in a 12mm by 12mm BGA package.
Microsoft's HPU is the chip that makes the HoloLens possible. Rather than bogging down the CPU or GPU with the additional processing, Microsoft instead design a custom chip set they named the HPU. The tech behind HoloLens is really exciting and will completely change the way we think about computers with a completely new way to compute in out world.




Microsoft is pushing some really cool, really quality tech. I have really enjoyed working with the Surface line and am excited to see what will be possible with the new HoloLens.
Yes they are, they have totally reinvented themselves under the new CEO. I'm planning on getting a Surface 3 soon, and either the new Surface Pro 5 or the Surface Book 2 when they release next year.
I bought a refurb'd Pro 2 as a spare machine to have around at a steal for $330 and I use it more than any other machine in my house. I use it for sketching, and quick photo editing but with the i5 Haswell it runs Lightroom really well. Great machines that fit me perfectly... I'll be adding another one soon!
Yeah I want the Surface 3 to sketch and use as a notebook using OneNote.
