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.
