ITPEC IP April 2022 Question 13
Which of the following is a chip that is used in image processing in devices such as PCs and smartphones, and is also used for large amount of calculation processing in AI?
Explanation
GPU — the Graphics Processing Unit handles image processing and the heavy parallel calculation of AI.
A GPU has a very large number of simple arithmetic units that apply the same operation to many pixels or data values at once. Built for drawing graphics in PCs and smartphones, the same parallel power suits the matrix calculations of machine learning, so GPUs are widely used for AI training and inference.
Answer (c)
Why not others:
- •(a) AR — Augmented Reality overlays computer-generated information on the real world; it is a technology, not a chip
- •(b) DVI — Digital Visual Interface is a standard for connecting a display to a computer
- •(d) MPEG — is a family of standards for compressing video and audio, not a processor
Key rule: A GPU accelerates work that repeats the same calculation on large amounts of data; the CPU stays in charge of general, sequential processing.
