What is OpenCores?


The reference community for Free and Open Source gateware IP cores

Since 1999, OpenCores is the most prominent online community for the development of gateware IP (Intellectual Properties) Cores. It is the place where such cores are shared and promoted in the spirit of Free and Open Source collaboration.

The OpenCores portal hosts the source code for different digital gateware projects and supports the users’ community providing a platform for listing, presenting, and managing such projects; together with version control systems for sources management.

OpenCores is also the place where digital designers meet to showcase, promote, and talk about their passion and work. They do this through forums, news collectors, and much more!
