First, you need (maybe more than one) a broken HoloLens
About five or six years ago, a friend lent me a first-generation HoloLens, and the experience is still unforgettable.
HoloLens：
HoloLens is a mixed reality headset developed by Microsoft. The glasses track your movement and gaze, generating appropriate virtual objects projected into your eyes. Because the device knows your position, you can interact with virtual 3D objects

Differences Between FPGA, ARM, ASIC, and SoC

Click on the blue text above to follow us
1. ASIC
ASIC, or Application-Specific Integrated Circuit, refers to integrated circuits designed and manufactured to meet the specific needs of a particular user and electronic system. Currently, using CPLD (Complex Programmable Logic Device) and FPGA (Field Programmable Gate Array) for ASIC design is one of the most popular methods. They share the common feature of being user-programmable
