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).
Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 [2] which developed and sold computers, computer components, software, and information technology services.
UltraSPARC II dual-core. The Gemini was the first attempt by Sun to produce a multithreaded microprocessor. It had taped out, but was cancelled before it was introduced after the announcement of UltraSPARC T1 Niagara microprocessor in early 2004. It consisted of two UltraSPARC II cores and an on-die L2 cache on a single chip.
The Sun Microsystems UltraSPARC processor is a type of RISC microprocessor.. In electronics and computer science, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks.
The UltraSPARC III Cu, code-named "Cheetah+", is a further development of the original UltraSPARC III that operated at higher clock frequencies of 1002 to 1200 MHz. It has a die size of 232 mm 2 and was fabricated in a 0.13 μm, 7-layer copper metallization , CMOS process by Texas Instruments.
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.
Oracle Solaris is a proprietary Unix operating system offered by Oracle for SPARC and x86-64 based workstations and servers.Originally developed by Sun Microsystems as Solaris, it superseded the company's earlier SunOS in 1993 and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider.
