Circuits computing just right
Try FloPoCo without installing it from our experimental web interface.Version 5.0 is taking shape in the git, version 4.1.2 is still the latest stable release. release notes
FloPoCo is a generator of arithmetic cores (Floating-Point Cores, but not only) for FPGAs (but not only).
The first motto of FloPoCo is that arithmetic on FPGAs should not mimick processor arithmetic. By designing radically new operators, one may obtain more accurate results with less hardware in less time. This thesis was first detailed in this document.
The second motto of FloPoCo is to enable computing just right. All FloPoCo operators are
FloPoCo is not a library of operators, but a generator of operators written in C++. It inputs operator specifications, and outputs synthesizable VHDL.
While waiting for the next release (we are working on it, honest) you may want to read the 2-page paper Reflections on 10 years of FloPoCo.
FloPoCo is open-source, contributions are welcome!
FloPoCo is distributed under the FloPoCo license. It is a modified AGPL, so that the code generated by FloPoCo is itself available under LGPL.
Do not hesitate to contact us to negociate a commercial license.
For some slides, see a FloPoCo tutorial at HiPEAC 2013.

Some of FloPoCo's operator code is based on FPLibrary and HOTBM code by Jérémie Detrey.
The following people have contributed to FloPoCo in some way (bug reports, porting, etc): Greg Davey, Mariusz Grad, Daniele Mastrandrea, Pedro Echeverría Aramendi.
FloPoCo uses Sollya, ScaLP, WCPGlib, and relies heavily on GMP and MPFR.
FloPoCo is essentially developed using Free Software. Special thanks to the NVC project for providing us a perfectly useable VHDL simulator.
