Headset HoloLens enables holographic computing unit, which includes 24 cores
Previously it was known that a headset-based augmented reality is the Intel Atom x5-Z8100 with four cores, clocked at a mere 1.04 GHz.
But now the developers talked about the fact that the bulk of the difficult work he did not, and the so-called holographic computing unit (holographic processing unit or HPU), which is carried out by TSMC on 28-nanometer process technology.
This holographic computing unit placed in the enclosure 12 x 12 mm, contains as much as 24 cores Tensilica DSP (Digital Signal Processing), which receive the data from all the sensors and doing the processing. According to developers, HPU can run up to a trillion operations per second. By the time when data is sent to the Intel Atom, it remains only to Refine them, although the main problem, as already noted, is performed by HPU.
HPU got 8 MB of embedded SRAM memory, and 1 GB of RAM LPDDR3. This is in addition to 1 GB of RAM, which is used in conjunction with a processor Intel Atom x5-Z8100. HPU consumes less than 10 watts of electricity.
Recently, it was reported that the HoloLens has become easier to buy.
