UltraSPARC IV
The UltraSPARC IV ''Jaguar'' and follow-up UltraSPARC IV+ ''Panther'' are microprocessors designed by Sun Microsystems and manufactured by Texas Instruments. They are the fourth generation of UltraSPARC microprocessors, and implement the 64-bit SPARC, SPARC V9 instruction set architecture (ISA). The UltraSPARC IV was originally to be succeeded by the UltraSPARC V ''Millennium'', which was canceled after the announcement of the ''Niagara'', now UltraSPARC T1 microprocessor in early 2004. It was instead succeeded by the Fujitsu-designed SPARC64 VI. The UltraSPARC IV was developed as part of Sun's Throughput Computing initiative, which included the UltraSPARC V ''Millennium'', ''Gemini'' and UltraSPARC T1 ''Niagara'' microprocessors. Of the four original designs in the initiative, two reached production: the UltraSPARC IV and the UltraSPARC T1. Whereas the ''Millennium'' and ''Niagara'' implemented Multithreading (computer architecture)#Coarse-grained multithreading, block multithread ...

Transistor
A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electric power, power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminal (electronics), terminals for connection to an electronic circuit. A voltage or Electric current, current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest inventions. Physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transisto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun Microprocessors
The Sun is the star at the centre of the Solar System. It is a massive, nearly perfect sphere of hot Plasma (physics), plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. It is by far the most important source of energy for life on Earth. The Sun has been an The Sun in culture, object of veneration in many cultures. It has been a central subject for astronomical research since Ancient history, antiquity. The Sun orbits the Galactic Center at a distance of 24,000 to 28,000 light-years. Its distance from Earth defines the astronomical unit, which is about or about 8 light-minutes. Solar radius, Its diameter is about (), 109 times that of Earth. solar mass, The Sun's mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System.

MDR also hosted an annual conference, the Microprocessor Forum, and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireplane
Fireplane is a computer internal interconnect created by Sun Microsystems. The Fireplane interconnect architecture is an evolutionary development of Sun's previous Ultra Port Architecture (UPA). It was introduced in October 2000 as the processor I/O interconnect in the Sun Blade 1000 workstation, followed in early 2001 by its use in the Sun Fire and Sun Fire 15K series enterprise servers. These coincided with the popular expansion of the web in the dot com boom and a shift of Sun's main market from Unix workstations to datacenter servers such as the Starfire, supporting high traffic web sites. Peak performance (in the Sun Blade 1000) reached 67.2 GBytes/second or a sustained 9.6 Gbit/s (2.4 Gbit/s for each processor). Each generation of Sun architecture had involved upgraded processors and matching upgrades to the bus or interconnect architectures that supported them. By this time, fast access to memory was becoming more important than simple CPU instruction spee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Reduced Instruction Set Computing
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. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more code) in order to accomplish a task because the individual instructions perform simpler operations. The goal is to offset the need to process more instructions by increasing the speed of each instruction, in particular by implementing an instruction pipeline, which may be simpler to achieve given simpler instructions. The key operational concept of the RISC computer is that each instruction performs only one function (e.g. copy a value from memory to a register). The RISC computer usually has many (16 or 32) high-speed, general-purpose registers with a load–store architecture in which the code for the register-register instructions (for performin ...

Sun Fire
Sun Fire is a series of server (computing), server computers introduced in 2001 by Sun Microsystems (since 2010, part of Oracle Corporation). The Sun Fire branding coincided with the introduction of the UltraSPARC III processor, superseding the UltraSPARC II-based Sun Enterprise series. In 2003, Sun broadened the Sun Fire brand, introducing Sun Fire servers using the Intel Xeon processor. In 2004, these early Intel Xeon models were superseded by models powered by AMD Opteron processors. Also in 2004, Sun introduced Sun Fire servers powered by the UltraSPARC IV dual-core processor. In 2007, Sun again introduced Intel Xeon Sun Fire servers, while continuing to offer the AMD Opteron versions as well. SPARC-based Sun Fire systems were produced until 2010, while x86-64 based machines were marketed until mid-2012. In mid-2012, Oracle Corporation ceased to use the Sun Fire brand for new server models. Operating systems UltraSPARC-based Sun Fire models are licensed to run the Solar ...
