|---|---|
| 궁금했던 점 | How should mobile GPU and NPU execution be combined under a shared memory-bandwidth limit? |
| 해본 것 | The study characterizes GPU/NPU behavior and builds HeteroInfer with heterogeneous parallelism and fast synchronization on Snapdragon 8 Gen 3. |
| 당시 조건 | Venue and publication year are pending verification.
Peak accelerator specifications obscure synchronization, operator support, and unified-bandwidth contention in real SoCs. Verification: arXiv abstract/full text, DOI metadata, and official SOSP listing; confidence=high. |
| 실제 결과 | workloads=mobile LLM inference on Snapdragon 8 Gen 3; baselines=GPU-only and NPU-only; metrics=inference speed; results=1.34–6.02x speedup |
| 왜 그랬는지 | SoC-wide bandwidth and synchronization, not isolated TOPS, determine usable heterogeneous speedup. |
| 다음에 기억할 것 | Profile shared bottlenecks and partition operators across accelerators jointly. |
| 언제 맞는지 | On-device LLM inference on unified-memory mobile SoCs.
Limits: Results are tied to one modern Snapdragon platform and its GPU/NPU software stack. |
| 신뢰도 | 낮음 |

Canonical title: Characterizing Mobile SoC for Accelerating Heterogeneous LLM Inference
Question: How should mobile GPU and NPU execution be combined under a shared memory-bandwidth limit?
Context: Peak accelerator specifications obscure synchronization, operator support, and unified-bandwidth contention in real SoCs.
Method: The study characterizes GPU/NPU behavior and builds HeteroInfer with heterogeneous parallelism and fast synchronization on Snapdragon 8 Gen 3.
Evaluation: workloads=mobile LLM inference on Snapdragon 8 Gen 3; baselines=GPU-only and NPU-only; metrics=inference speed; results=1.34–6.02x speedup
Interpretation: SoC-wide bandwidth and synchronization, not isolated TOPS, determine usable heterogeneous speedup.
Reusable lesson: Profile shared bottlenecks and partition operators across accelerators jointly.
Applicability: On-device LLM inference on unified-memory mobile SoCs.
Limits: Results are tied to one modern Snapdragon platform and its GPU/NPU software stack.
