The UltraSPARC is a microprocessor developed by Sun Microsystems and fabricated by Texas Instruments, introduced in mid-1995. It is the first microprocessor from Sun to implement the 64-bit SPARC V9 instruction set architecture (ISA).
It is a single UltraSPARC V9 core capable of 4-way SMT. Like the T1, the source code is licensed under the GPL. OpenSPARC T2, released in 2008, a 64-bit, 64-thread implementation conforming to the UltraSPARC Architecture 2007 and to SPARC Version 9 (Level 1). Source code is written in Verilog, and licensed under many licenses.
The UltraSPARC II, code-named "Blackbird", is a microprocessor implementation of the SPARC V9 instruction set architecture (ISA) developed by Sun Microsystems. Marc Tremblay was the chief architect. Introduced in 1997, it was further development of the UltraSPARC operating at higher clock frequencies of 250 MHz, eventually reaching 650 MHz.
The UltraSPARC III, code-named "Cheetah", is a microprocessor that implements the SPARC V9 instruction set architecture (ISA) developed by Sun Microsystems and fabricated by Texas Instruments. It was introduced in 2001 and operates at 600 to 900 MHz. It was succeeded by the UltraSPARC IV in 2004. Gary Lauterbach was the chief architect.
The T1 is a new-from-the-ground-up SPARC microprocessor implementation that conforms to the UltraSPARC Architecture 2005 specification [1] and executes the full SPARC V9 instruction set. Sun has produced two previous multicore processors (UltraSPARC IV and IV+), but UltraSPARC T1 was its first microprocessor that is both multicore and ...
The UltraSPARC IV was the first multi-core SPARC processor, released in March, 2004. [1] Internally, it implements two modified UltraSPARC III cores, and its physical packaging is identical to the UltraSPARC III with the exception of one pin. [2] The UltraSPARC III cores were improved in a variety of ways.
Visual Instruction Set, or VIS, is a SIMD instruction set extension for SPARC V9 microprocessors developed by Sun Microsystems. There are five versions of VIS: VIS 1, VIS 2, VIS 2+, VIS 3 and VIS 4. There are five versions of VIS: VIS 1, VIS 2, VIS 2+, VIS 3 and VIS 4.
The UltraSPARC T1 based Sun Fire T2000 and T1000 servers were launched in December 2005 and early 2006, respectively. [ 1 ] [ 3 ] They were later rebranded to match the name of the UltraSPARC T2 and T2 Plus based Sun SPARC Enterprise T5**0 servers.
