Here’s for the hardware enthusiasts and open source advocates. 😉
OpenCores is a loose collection of people who are interested in developing hardware, with a similar ethos to the free software movement. Currently the emphasis is on digital modules called ‘cores’, since FPGAs have reduced the incremental cost of a core to approximately zero. Activity is centered around the opencores web site (http://www.opencores.org).
There is no formal affiliation between the people who make up opencores. They are a bunch of people who just happen to be walking in the same direction along a road. This is a dynamic group. People regularly join and leave. As a whole, the group progresses through the independent contributions of individuals.
Also, for those who might be interested in HDL codes for games they enjoyed as kids, do take some time to visit this site: FPGA Arcade
