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
