Sun UltraSPARC Microprocessor

The Sun Microsystems UltraSPARC is a 64-bit superscalar processor released in late 1995 with help from Texas Instruments, following the widely successful earlier SPARC (Scalable Processor ARChitecture) designs. Being a scalable chip, as the silicon semiconductor technology improves, the design rules may be tightened, resulting in a more compact layout that takes advantage of innovations without a total redesign of the architecture.
