OpenSPARC is an open source hardware project started in December 2005. The initial contribution to the project was Sun Microsystems' Register transfer level (RTL) Verilog code for a full 64-bit, 32-thread microprocessor, the UltraSPARC T1 processor. On 21 March 2006, Sun released the source code to the T1 IP core under the GNU General Public License.

On 7 August 2007, Sun announced that the UltraSPARC T2 processor's RTL will also be made available via the OpenSPARC project.
