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).
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.
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.
Sun Microsystems' UltraSPARC T2 microprocessor is a multithreading, multi-core CPU. It is a member of the SPARC family, and the successor to the UltraSPARC T1 . The chip is sometimes referred to by its codename, Niagara 2 .
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 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.
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.
The SPARC T3 microprocessor (previously known as UltraSPARC T3, codenamed Rainbow Falls, [1] and also known as UltraSPARC KT or Niagara-3 during development) is a multithreading, multi-core CPU produced by Oracle Corporation (previously Sun Microsystems).
