Real-Time Performance Evaluation
1. System Configuration
- Kernel Version: 6.6.73-rt47-v8-16k-RTLC+
- Scheduler Policy: SCHED_FIFO
- Test Tool:
cyclictest - Test Parameters:
- Priority: 95
- Interval: 1000 μs
- Duration: 1 minute
- Threads: 4
2. Test Results
| Thread | Min Latency (μs) | Avg Latency (μs) | Max Latency (μs) |
|---|---|---|---|
| 0 | 1 | 2 | 14 |
| 1 | 1 | 2 | 8 |
| 2 | 1 | 2 | 13 |
| 3 | 1 | 2 | 10 |
3. Analysis
- The maximum observed latency is only 14 μs, which indicates excellent real-time responsiveness.
- All threads reported very consistent low latencies, both in terms of minimum and average values.
- The low jitter suggests a stable real-time environment with efficient scheduling.
4. Conclusion
The system demonstrates outstanding real-time performance, with low, stable, and predictable response characteristics. It is well-suited for real-time embedded applications like FluxSand.
