Performance Tuning
DSP pipeline throughput clinic
Optimizes filter chains and DMA staging for biosignal paths without sacrificing numeric stability.
Indicative fee: 4 500 000 Ft · informational only
Scope narrative
When sample rates climb, small inefficiencies compound. We benchmark your DSP chain on-target, propose numerically stable alternatives, and show how each step affects CPU load and memory bandwidth.
Included focus areas
- Cycle-accurate profiling hooks tailored to your SoC
- Filter coefficient stability checks with documented tolerances
- DMA burst tuning with oscilloscope correlation plan
- Optional NEON/DSP intrinsic pass where your toolchain allows
- Handover graphs for clinical algorithm owners
- Test vector pack for regression suites
Outcomes you can archive
- Higher stable throughput on the same silicon
- Cleaner collaboration between algorithm and firmware teams
- Evidence bundle for design reviews
FAQ
Do you rewrite algorithms?
We propose firmware-side optimizations first. Algorithm changes stay clinician-governed.
What if floating point is banned?
We document fixed-point paths with error budgets you can defend.
Can we pause mid-sprint?
Yes with written notice; we reconcile hours against the agreed checkpoint table.
Experience notes
The DMA burst tuning shaved 11% CPU without touching coefficients. We kept the scope honest when NEON was not worth it.
