Open Source Hardware

Frank Hannig, Jurgen Teich
2021 Computer  
The open source movement has brought open collaboration and open licensing into all kinds of domains, ranging from wikis and Wikipedia through open access to this month's column on open source hardware  ...  IP cores can be owned and used by an individ ual or licensed to others. Many com panies in the chip design business are fabless and solely focus on develop ing and licensing IP cores.  ...

From Open Source Software to Open Source Hardware [chapter]

Robert Viseur
2012 IFIP Advances in Information and Communication Technology  
We define the open hardware concept and determine intellectual property tools we can apply to open hardware, with a strong focus on open source licenses and practices.  ...  The open source software principles progressively give rise to new initiatives for culture (free culture), data (open data) or hardware (open hardware).  ...  That is a problem in the software developments based on reusable components and, by extension, with open source hardwares (e.g.: IP cores sharing).  ...
