Manual kernels¶

This folder contains manual (hand-tuned) kernel examples that use explicit buffering, synchronization, and pipeline control for maximum performance on supported NPUs.

If you are new to PTO programming, start from the ISA and tutorials first:

• Programming tutorials: docs/coding/tutorial.md
• Optimization notes: docs/coding/opt.md
• PTO ISA reference: docs/PTOISA.md

Platforms¶

• a2a3/: Manual kernels for Ascend A2/A3 platforms.
• a5/: Manual kernels for Ascend A5 platforms.
• common/: Cross-platform manual kernels (shared examples).

How to run¶

Each subdirectory is a standalone example with its own build/run instructions. See:

• a2a3/README.md
• a5/README.md
• common/flash_atten/README.md
