Fixed-point DSP consulting

Bring Mantissa onto your team for the hard part of a signal-processing project — the fixed-point port, and the verification that proves it is right.

How we can help

Take a floating-point reference and produce a fixed-point implementation that meets your accuracy and headroom targets.

Profile an existing port to find exactly where dynamic range or precision is being lost, with measurements you can act on.

Set up golden-vector test harnesses and a reference flow so regressions are caught the moment they appear.

Track down fixed-vs-float divergence in running code across Visual Studio, VS Code, and GDB sessions.

Review of fixed-point arithmetic, plus workshops to level up your team's Q-format and quantization fluency.

Scope. A short call to understand the algorithm, the build, and what “done” looks like.
Plan. A focused proposal — deliverables, timeline, and how success is measured.
Work. Hands-on engineering, with the Mantissa app and methodology applied throughout.
Verify. Bit-exact results, a test harness you keep, and a written hand-off.

Tell us about the project — the reference code, the target, and the deadline. Engagements start with a short scoping call.
