# hsfzxjy/npunlock

> A toolkit for writing and running custom C kernels on Intel Core Ultra NPUs, bypassing the public graph-level-only stack. It reconstructs the path from C code to a runnable NPU kernel, verified on Windows x64 with Meteor Lake / NPU3720.

- Magnitude: 3.6 out of 10 — Early signal
- Stars: 37 total · +17 stars today, ≈ 32 by evening
- Star trust: star growth looks organic
- Category: Hardware, IoT & robotics · Language: C · License: Apache-2.0 · Created: 2026-09-20 · Last push: 2026-09-23
- GitHub: https://github.com/hsfzxjy/npunlock · Page: https://gitnova.dev/en/r/hsfzxjy/npunlock

## Useful for

- Run a custom FP32 GELU kernel on NPU3720 and verify against NumPy
- Embed a C kernel into an NPU graph via npunlock Python bindings
- Call libm functions such as tanhf inside a custom NPU kernel

## Why it’s here

- 17 stars so far today, about 32 expected by the end of the day.
- The spike has held for 2 days in a row — not a one-off blip.
- The repository is 3 days old and already has 37 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 0
- Issues and pull requests: 0
- Watchers: 1
- Average over the last week: 13 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 3

## Stars per day, last 4 days (oldest → newest, today is partial)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
