HoloLens have intelligent processor to avoid delays in the image – Globo.com

HoloLens , augmented reality device of Microsoft , will be equipped with a specific processor named HPU (acronym in English for Holographic Processing Unit), which runs the ordinary when compared to the CPUs used in mobile phones and tablets. In addition to the HPU, prepared to avoid delays in the image, the headset will Intel processor similar to smartphones, with RAM and a set of sensors that give the glasses the ability to track user’s movement.

Each of the Tensilica cores has a specific function, such as follow the readings of accelerometer or gyroscope HoloLens. These nuclei are of the DSP, a processor designed to work with specific functions, such as reading in real time of a large volume of data from the outside world.

HPU has sole memory of 8 MB of SDRAM and needs only 10 watt to process a volume of one trillion calculations per second. This is all essential to the intelligence of the processor, because otherwise the sensors of the information of the readings will be harvested late. If this occurs, the positioning of images projected by the glasses can display lag, affecting the decisive form of user experience.

In addition to the exotic processor, HoloLens is equipped with an Intel Atom, instead of DSP cores, it has Intel x86 cores, designed for processing general information. Unlike highly specialized operation of the HPU, the Atom CPU is ideal to effectively run the applications and Windows compatible games.

According to the statement from Microsoft, the HPU is 200 times faster than Atom CPU for processing the readings of the positioning sensors HoloLens.

Intel CPU also lies within the graphics processor Intel HD graphics. In addition to these elements, the HoloLens account with 1 GB of DDR3 RAM standard.
