Abstract :
UltraSPARC is the first microprocessor from Sun Microsystems´ SPARC Technology Business to implement the new 64-bit SPARC V9 architecture. ULtraSPARC is equipped with unique multimedia capabilities and is capable of 4-way superscalar instruction dispatch, with an emphasis on maximal system efficiency and throughput in the execution of complex, memory-intensive applications. UltraSPARC maintains a strict binary compatibility with the thousands of existing 32-bit applications developed for other SPARC processors. This paper describes the feature set and operation of UItraSPARC.
