ISR Budget Recovery Sprint
Tightens interrupt service routines and DMA hand-offs when sporadic latency spikes appear under clinical workload simulations.
Intensive sprint with shared channel updates
Timeline: 3 weeks
Indicative pricing: 9,000,000 KRW
Lead consultant: Jonas Adeyemi
Real-time performance engineer focused on mixed bare-metal and RTOS medical controllers.
Schedule a callScope narrative
We pair trace capture with code inspection to separate measurement noise from real contention. The sprint ends with a stabilization plan that respects your quality standards trace matrix without rewriting unrelated subsystems.
What we examine
- ISR length histograms with annotated hotspots
- NVIC priority scheme sanity review
- DMA double-buffering and cache coherency checks
- SPI/I2C timing budget tables
- RTOS deferred interrupt path mapping
- Sensor fusion thread interaction review
- Optional MISRA-aligned patch guidance
What you can drop into a review deck
- A ranked backlog of ISR and DMA adjustments
- Updated timing assumptions for subsystem owners
- A concise risk note for verification leads
FAQ
We deliver patches as suggestions inside your version control conventions. Your team merges, tests, and signs releases.
Recent experience notes
ISR Budget Recovery Sprint caught a SPI re-entrancy issue our bench tests missed. The DMA hand-off notes were especially crisp.
