| 概念 | 说明 |
|---|---|
| NpuArch | 芯片架构，定义指令集和微架构 |
| SocVersion | 片上系统版本，软件命名标识 |
| NpuArch | NPU_ARCH | 目录 | 芯片型号 |
|---|---|---|---|
| DAV_1001 | 1001 | arch32 | Ascend910 |
| DAV_2002 | 2002 | arch32 | Ascend310P |

| FP8 格式 | 8-bit 浮点 | 量化、动态量化 |
Profile PyPTO kernels in-core with the Ascend msprof op-simulator — cycle-accurate per-kernel traces. Use when the user wants to profile a built case, inspect kernel timing or instruction streams, or generate MindStudio Insight traces.
Tune cube/matmul tile sizes (row tile, N fragment, K fragment) for a PyPTO kernel — analytic hints, an on-chip buffer constraint model, and an empirical device sweep. Use when optimizing a matmul/cube's throughput, sizing the row / N / K tiles, resolving Mat (L1) / L0C / UB buffer overflows, or trading one tile dim for another.
Locate which pypto commit introduced a precision regression. Only pypto and its corresponding simpler (submodule) are tracked — ptoas and pto-isa versions are not part of the bisect. If the culprit is a simpler submodule bump, performs a second-level bisect within simpler.
Reproduce a reported problem, collect dependency versions, and create a GitHub issue. Use when the user wants to file a bug, request a feature, or create any GitHub issue.
Ascend C 开发资源索引（本地+在线）。提供：(1) 本地 API 文档索引、示例代码映射，(2) 在线文档搜索功能，(3) 资源查找优先级，(4) Explore Agent 使用指南。优先使用本地资源，仅在本地检索不到时使用在线搜索。
Complete git commit workflow including pre-commit checks, staging, message generation, and verification. Use when creating commits or preparing changes for commit.
