Qualcomm Hexagon 手册归档与版本索引
本页归档从本地 eperf-exporter/docs/references/hexagon-npu 同步的 Qualcomm Hexagon 手册与辅助素材。原目录含 25 个 PDF 文件、24 份不同的文档：V81 HMX 的官网版与镜像版逐字节相同，归档只保存一份，清单保留两种来源。
PDF 写入根级 assets/papers/，文件名以带年份的 BibTeX key 开头；元数据已登记在 content/references.bib。文件名、原始来源、大小与 SHA256 可见完整归档清单和校验和清单。
1. 先读哪些手册
表 1｜主要手册与阅读重点
| 手册 | 重点 |
|---|---|
| V79 core[1] | §1.1（PDF 第 5–8 页）核心结构；§3（第 12 页起）寄存器；§4.3（第 32–33 页）VLIW packet |
| V79 HVX[2] | §1.2（PDF 第 5–6 页）vector context 与 scalar thread；宽向量寄存器与访存规则 |
| V81 HMX[3] | §2.1–§2.2（PDF 第 4–5 页）scalar registers 配置、VTCM 操作数与矩阵乘加；手册只展开 FP16 |
V79 core 与 HVX 的官网在线入口分别为 80-N2040-60 和 80-N2040-61。下表的 PDF 获取链接指向 docs.alexrp.com 镜像；它不是 Qualcomm 官网。V81 HMX 另有源目录保存的官网下载副本，已在导入时验证与镜像的 SHA256 一致。

3. v73 / v79 的 HMX 编程介绍从哪里读
本次没有找到 v73 或 v79 的独立公开 HMX Programmer Reference Manual。 截至 2026-10-15，所核对的手册镜像目录中，v73 / v79 提供 core 与 HVX 手册，HMX PRM 则只有 v81hmx-manual-index。这说明本次取得的资料范围，不能据此断言其他渠道没有相关手册。
v73 / v79 的实用编程入口可以看 llama.cpp Hexagon 后端：其目标构建配置明确生成 v73、v75、v79 与 v81 版本，开发文档列出各架构的 DSP 库[25]。这类资料可以回答如何编排运算和数据，具体设备能否使用 HMX 仍取决于硬件与 runtime。
代码中的 HMX 指令封装覆盖 FP16 activation / weight 加载与乘加、bias 加载、累加器清零及结果写回；tile 内层计算展示多个 tile 的指令组织[25]。可以据此沿着 VTCM 操作数 → HMX 累加 → 参数/转换 → VTCM 写出 理解一个具体实现。
这些是开源实现与特定精度的代码证据，不是 v73 / v79 全部指令、内部阵列或数值行为的完整规范。V81 HMX 手册用于补充概念；跨代编码与结果一致性仍需按目标设备核对。
本节源码统一 pin 到 ggml-org/llama.cpp@c114bd4c58a9a39eeb50f115418389a195fdd697，链接已精确到行。
hmx-manual-index. Hexagon 手册镜像目录（2026-10-15 核对）：https://docs.alexrp.com/hexagon/ 。本地目录快照见原始归档索引。 ↩
4. 辅助素材与来源边界
- 导入源目录的说明、原始 SHA256 清单和镜像目录快照：保留导入时的来源记录。
手册按版本描述编程接口；设备的 context 数、VTCM 容量及运行带宽需要对应芯片与实验条件。V81 HMX 手册只覆盖 FP16，不能从其篇幅推断其他精度不存在，也不能直接把全部编码移用到 v79[3]。
