A Sun UltraSparc.

This page is going to discuss the upgrades in Ultra SPARC, and will discuss some issues thereof.

The UltraSPARC processors were designed by Sun Microsystems and implement the SPARC version 9 (sparcv9) architecture. This architecture natively supports 64 bit processing by extending the virtual address space to 64 bits and widening the general purpose registers to 64 bits.
