Fixed-point DSP studio
Get fixed-point right.
Mantissa helps signal-processing teams port, verify, and debug fixed-point code — through consulting, a purpose-built desktop app, and practical training.
Three ways we help
Consulting
Hands-on help porting and verifying fixed-point DSP — codec bring-up, precision audits, and bit-exact debugging alongside your team.
Explore consulting → 02Mantissa App
The desktop suite: compare waveforms, debug live fixed-vs-float values across builds, and see exactly where precision is lost.
Open the app → 03Learning
Step-by-step guides and hands-on labs for fixed-point signal design — from Q-format basics to debugging a real codec port.
Start learning →Fixed-point ports are where codecs quietly lose quality — and where the bugs are hardest to see.
Mantissa is built around that problem: the tooling, the methodology, and the hands-on help to ship bit-exact code with confidence. Get in touch →
