IPA IP 2020 Question 65
A question IPA Japan published in 令和2年度 10月 ITパスポート試験 公開問題 問65, translated into English. ITPEC is based on the same exams.
Same question on ITPEC: Apr 2022 Q13
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.
