ITPEC FE Morning October 2023 Question 13

Flynn's Taxonomy — SIMD — architecture where one instruction operates on multiple data simultaneously.

Flynn's four categories:
- SISD — Single Instruction, Single Data (classic single-core CPU)
- SIMD — Single Instruction, Multiple Data (GPU, vector processors)
- MISD — Multiple Instruction, Single Data (rare, theoretical)
- MIMD — Multiple Instruction, Multiple Data (multi-core, distributed systems)

Key phrase: "same instruction on multiple data" → SIMD

Why not others:
- (a) MIMD — multiple instructions on multiple data (multi-processor systems)
- (b) MISD — multiple instructions on single data (rarely implemented)
- (d) SISD — single instruction on single data (traditional uniprocessor)

Key rule: Decode the acronym — first letter pair = instruction count (SI/MI), second pair = data count (SD/MD).
