OpenCores is the world’s largest site/community for development of hardware IP cores as open source. host the source code for different digital HW projects (IP-cores, SoC, boards, etc) and support the users with different tools, platforms, forums and other useful information.

The aim of the OpenRISC project is to create free and open source computing platforms available under the GNU (L)GPL license. The platforms aim to provide: 1) a free, open source RISC architecture with DSP features, 2) a set of free, open source implementations of the architecture
a complete set of free, and 3) open source software development tools, libraries, operating systems and applications.
