Welcome to FreeCores !
FreeCores is a project that was started to provide and foster a place for the sharing and development of hardware designs, in the spirit of freedom.
FreeCores was formed partially in response of the announcement that OpenCores may be going commercial. Other reasons include an apparently large difference in philosophy. We plan to eventually fork all of the current OpenCores designs, and hope that others will join us!
If you are an OpenCores developer and would like to join the FreeCores community, please contact the mailing list for assistance in porting over your project to our Subversion repository and getting commit access.
2007-06-08: This project has just started, and there is not much here yet. If you want to get involved, jump right in! Sign up on our freecores-devel mailing list, help get the wiki in shape, ask for commit access to subversion, etc.
(Note that to avoid the most egregious wiki spam, you need to be logged in to edit certain pages, like this front page.)
There is a mailing list available on the freecores sourceforge site. (2007-06-12: problems with mailing list seem to be resolved)
Subversion repository information. To get commit access to subversion, please ask on the freecores-devel mailing list.
A preliminary list of free cores follows.

- Gaisler Research Leon2 (SPARC v8, 32-bit, written in VHDL)
- Steve Rhoads's Plasma Core (MIPS-I, 32-bit, written in VHDL)
- Beyond Semiconductor OpenRISC 1200 (OR1K, 32-bit, written in Verilog)
- Simply RISC S1 Core (SPARC v9, 64-bit, written in Verilog)
- Thorn Aitch's Aquarius (SuperH SH-2, 32-bit, written in Verilog)
Other Free Cores
- Several high-quality free cores provided by ASICS.ws (written in Verilog)
- Nguyen, Mohor & Markovic's FastEthernet MAC (written in Verilog)
- Gorban, Mohor & Markovic's UART 16550 (written in Verilog)
ToDo List
- Put actual useful content here on the wiki. -- wjl
- Review the current Free Ant logo... This one is very ugly as well!!! -- fafa1971
- Start populating SVN in a meaningful way
- Start indexing and importing Cores.
