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
