- S1 Core
S1 Core (codename Sirocco) is an
open source hardwaremicroprocessor design developed bySimply RISC . Based onSun Microsystems 'UltraSPARC T1 , the S1 Core is licensed under theGNU General Public License , which is the license Sun chose for theOpenSPARC project.The main goal of the project is to keep the S1 Core as simple as possible to encourage developers. The major differences between T1 and S1 include:
* S1 Core only has one 64-bit
SPARC Core (supporting 1 to 4 independent threads of execution) instead of 8 cores;
* S1 Core adds a Wishbone bridge, a reset controller and a basicinterrupt controller ;
* the S1 Core environment can be run using only free tools on a common x86 Linux machine.ee also
