SPARC64 V

The SPARC64-V architecture comes from a joint venture between Sun Microsystems and Fujitsu in 2004. It belongs to the so-called Advanced Product Line (APL) based on the SPARC processor. The SPARC64 V was designed by HAL Computer Systems together with Fujitsu in 1999 , but the 64-bit core now presented differs radically from the prototype at that time due to its sheer cache sizes . The SPARC64-V processors were originally manufactured using copper - conductor tracks with a structure width of 0.13 µm, newer processors are manufactured with smaller structure widths. Incidentally, Fujitsu's SPARC64 V are the first processors outside the mainframe area that check the validity of a data bus line address.

At the beginning of 2008 the SPARC64 VII appeared with 2.7 GHz. This is the four-core version of the SPARC64 V. The SPARC64 VII is bus- compatible with the SPARC64 VI. The 8-core processor SPARC64 VIII was introduced in 2009.
