Program narrative
Realtime does not mean “fast”; it means predictable. You will profile loop jitter, design small scheduling islands, and practice cooperative patterns between ISRs and foreground tasks. Labs include a motor angle loop with enforced deadlines and a soft failure mode when timing slips.
What ships in the syllabus
- Jitter capture harness with histogram review
- Control loop timing budget spreadsheet
- ISR length budgeting with annotated assembly snippets
- Soft degradation modes when sensors stall
- Cooperative FIFO design between ISR and worker
- Measurement protocol for thermal drift impact
- Mentor review of loop stability narrative
Outcomes we can observe
- Present a timing budget for a two-loop system
- Implement a graceful derate path when deadlines slip
- Document measurement method for jitter claims

Embedded lead on warehouse robotics loops; teaches boring-as-a-feature reliability.
Cohort murmurs
Quote-first
Jitter harness from Realtime Loops course caught a SPI preemption issue we blamed on hardware.

Still sketching loop diagrams on paper, but the soft derate path from week 5 stopped a field rollback once.

Straight answers
Bare-metal cooperative patterns first; we map concepts to a small RTOS profile in the final week.
