What we do
Services
Mantissa works on fixed-point signal processing three ways. They share one goal — shipping code that stays bit-exact — and each one feeds the others.
Consulting
Fixed-point engineering, on demand.
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.
Explore consulting →- Fixed-point ports of floating-point reference code
- Precision audits — find where bits are being lost
- Bit-exact verification harnesses and golden vectors
- Live debugging of fixed-vs-float divergence
- Code review and team workshops
Mantissa App
The desktop suite for fixed-point work.
A Qt desktop application that makes fixed-point analysis and debugging a first-class workflow instead of a pile of one-off scripts.
Open the app →- Wave Compare — overlay float vs. fixed waveforms, MLD / MAD / SSNR
- Debugger — live fixed-vs-float values across VS, VS Code, GDB
- Precision diagnostics to locate the lossy buffer
- Free to download for Windows
Learning
Build real fixed-point intuition.
Practical, self-paced material that teaches the same methodology Mantissa applies on consulting work.
Start learning →- Step-by-step guides on Q-format and quantization
- Hands-on labs built on real fixed-point DSP code
- SFDR, FFT-bin planning, and watch-window techniques
- Free and self-paced
