## Performance Analysis

### Measurement Notes

1. **Hardware-Synchronized Timing**: Direct FPGA event detection eliminates software scheduling jitter
2. **Sub-millisecond Precision**: \~10us resolution
3. **Frame-Accurate Triggering**: LED triggers synchronized to exact camera frame events
4. **Reduced System Interference**: Dedicated timing hardware independent of OS scheduling

### Key Metrics Explained

* **Average Latency**: End-to-end time from camera trigger to display detection
* **Standard Deviation**: Measurement consistency (lower indicates more predictable timing)
* **Max Jitter**: Peak-to-peak variation in timing measurements
* **Std Dev %**: Standard deviation as percentage of average latency
* **Jitter %**: Maximum jitter as percentage of average latency
