| The [[http://www.gaisler.com/cms/index.php?option=com_content&task=view&id=13&Itemid=53|LEON3]] is a synthesisable VHDL model of a 32-bit processor compliant with the SPARC V8 architecture. The model is highly configurable, and particularly suitable for system-on-a-chip (SOC) designs. The full source code is available under the GNU GPL license, allowing free and unlimited use for research and education. LEON3 is also available under a low-cost commercial license, allowing it to be used in any commercial application to a fraction of the cost of comparable IP cores. | The [[http://www.gaisler.com/cms/index.php?option=com_content&task=view&id=13&Itemid=53|LEON3]] is a synthesisable VHDL model of a 32-bit processor compliant with the SPARC V8 architecture.
