IPA FE Subject A 2026 Question 3
A question IPA Japan published in 令和８年度 基本情報技術者試験 科目A 公開問題 問3, translated into English. ITPEC is based on the same exams.
Which of the following is an appropriate characteristic of the GPU, which is one of the processors?
Explanation
Many parallel floating-point units for fast 3D computation — a GPU (graphics processing unit) is a processor built for massively parallel arithmetic.
A GPU contains hundreds to thousands of simple arithmetic units that apply the same operation to many data items at once. Rendering 3D graphics repeats the same floating-point calculations (coordinate transformation, shading) for millions of vertices and pixels, so this parallel design makes it fast. The same strength is why GPUs are used to train and run AI models.
Answer (b)
Why not others:
- •(a) — a security chip that works independently of the OS and other hardware and keeps encryption keys safe is a TPM (Trusted Platform Module)
- •(c) — a device whose internal logic circuits can be reconfigured for the purpose is an FPGA (field-programmable gate array)
- •(d) — computing with qubits that hold 0 and 1 in superposition describes a quantum computer
Key rule: GPU: many parallel floating-point units (graphics, AI); TPM: tamper-resistant key storage; FPGA: reconfigurable logic; quantum computer: qubits in superposition.
