Many of us are excited about HoloLens. The Dev version costs $3000, so not everyone can afford one. Microsoft has decided to give everyone a first look at its Holographic Processing Unit anyway. As the Register reports, this is a custom-built 28nm coprocessor with 24 Tensilica DSP cores arranged in 12 clusters.
The HPU can perform a trillion calculations a second, including getting and processing data from sensors. There is also a 14nm Intel Atom x86 Cherry Trail SoC with 1 GB RAM and Windows 10 inside. More exciting HoloLens developments are expected in 2017.
