Explain GPU pipeline and execution hazards
Company: Arm
Role: Software Engineer
Category: Software Engineering Fundamentals
Difficulty: easy
Interview Round: HR Screen
Explain the following GPU architecture topics:
1. How a modern GPU renders a triangle from input vertices to final pixels.
2. How register read-after-write dependencies are handled in a pipelined processor or GPU execution pipeline.
3. What kinds of operations GPUs are especially good at, and why.
Focus on modern graphics hardware concepts, throughput, memory behavior, and execution scheduling.
Quick Answer: This question evaluates understanding of GPU architecture concepts including the graphics pipeline from vertices to pixels, register read-after-write hazards in pipelined execution, memory behavior, throughput considerations, and execution scheduling, reflecting competency in computer graphics and parallel processor design.
