Why are you opening the source code for the UltraSPARC T1?
Sun’s 64-bit UltraSPARC processors have been an industry standard for more than a decade. Our goal is to expand the SPARC community and lay the groundwork for a new generation of 64-bit hardware and multi-threaded software products. Sun has a long history of being associated with open standards and specifications and opening up the UltraSPARC-T1 design point is part of our overall open source strategy.
