MicroSPARC IIep
The microSPARC (code-named ''Tsunami'') is a discontinued microprocessor implementing the SPARC V8 instruction set architecture (ISA), developed by Sun Microsystems. It is a low-end microprocessor intended for low-end workstations and embedded systems. The microprocessor was developed by Sun, but the floating-point unit (FPU) was licensed from Meiko Scientific. It contains 800,000 transistors. There are two derivatives of the microSPARC-II (code-named ''Swift''): the microSPARC-II and microSPARC-IIep. The microSPARC-II is used in the SPARCstation 5. The microSPARC-IIep is a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun, and used in their JavaStation Network Computer.

Sun products included computer servers and workstations built on its own RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPARC
SPARC (Scalable Processor Architecture) is a reduced instruction set computer (RISC) instruction set architecture originally developed by Sun Microsystems. Its design was strongly influenced by the experimental Berkeley RISC system developed in the early 1980s. First developed in 1986 and released in 1987, SPARC was one of the most successful early commercial RISC systems, and its success led to the introduction of similar RISC designs from many vendors through the 1980s and 1990s. The first implementation of the original 32-bit architecture (SPARC V7) was used in Sun's Sun-4 computer workstation and server systems, replacing their earlier Sun-3 systems based on the Motorola 68000 series of processors. SPARC V8 added a number of improvements that were part of the SuperSPARC series of processors released in 1992. SPARC V9, released in 1993, introduced a 64-bit architecture and was first released in Sun's UltraSPARC processors in 1995. Later, SPARC processors were used in symm ...

Microprocessor
A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system. The integration of a whole CPU onto a single or a few integrated circuits using Very-Large-Scale Integration (VLSI) greatly reduced the cost of ...

Instruction Set Architecture
In computer science, an instruction set architecture (ISA), also called computer architecture, is an abstract model of a computer. A device that executes instructions described by that ISA, such as a central processing unit (CPU), is called an ''implementation''. In general, an ISA defines the supported instructions, data types, registers, the hardware support for managing main memory, fundamental features (such as the memory consistency, addressing modes, virtual memory), and the input/output model of a family of implementations of the ISA. An ISA specifies the behavior of machine code running on implementations of that ISA in a fashion that does not depend on the characteristics of that implementation, providing binary compatibility between implementations. This enables multiple implementations of an ISA that differ in characteristics such as performance, physical size, and monetary cost (among other things), but that are capable of running the same machine code, so that ...

Workstation
A workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by a single user, they are commonly connected to a local area network and run multi-user operating systems. The term ''workstation'' has been used loosely to refer to everything from a mainframe computer terminal to a PC connected to a network, but the most common form refers to the class of hardware offered by several current and defunct companies such as Sun Microsystems, Silicon Graphics, Apollo Computer, DEC, HP, NeXT, and IBM which powered the 3D computer graphics revolution of the late 1990s. Workstations offer higher performance than mainstream personal computers, especially in CPU, graphics, memory, and multitasking. Workstations are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulations like computational fluid dynamics, animation, medical imaging, image rendering, and ...

Embedded System
An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is ''embedded'' as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems. In either case, the processor(s) used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floating-point Unit
In computing, floating-point arithmetic (FP) is arithmetic that represents real numbers approximately, using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. For example, 12.345 can be represented as a base-ten floating-point number: 12.345 = \underbrace_\text \times \underbrace_\text\!\!\!\!\!\!^ In practice, most floating-point systems use base two, though base ten (decimal floating point) is also common. The term ''floating point'' refers to the fact that the number's radix point can "float" anywhere to the left, right, or between the significant digits of the number. This position is indicated by the exponent, so floating point can be considered a form of scientific notation. A floating-point system can be used to represent, with a fixed number of digits, numbers of very different orders of magnitude — such as the number of meters between galaxies or between protons in an atom. For this reason, floating-poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meiko Scientific
Meiko Scientific Ltd. was a British supercomputer company based in Bristol, founded by members of the design team working on the Inmos transputer microprocessor. History In 1985, when Inmos management suggested the release of the transputer be delayed, Miles Chesney, David Alden, Eric Barton, Roy Bottomley, James Cownie, and Gerry Talbot resigned and formed Meiko (Japanese for "well-engineered") to start work on massively parallel machines based on the processor. Nine weeks later in July 1985, they demonstrated a transputer system based on experimental 16-bit transputers at the SIGGRAPH in San Francisco. In 1986, a system based on 32-bit T414 transputers was launched as the ''Meiko Computing Surface''. By 1990, Meiko had sold more than 300 systems and grown to 125 employees. In 1993, Meiko launched the second-generation ''Meiko CS-2'' system, but Meiko ran into financial difficulties in the mid-1990s. The Meiko technical team and technology was transferred to a joint venture co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPARCstation 5
SPARCstation 5 or SS5 (code-named ''Aurora'') is a workstation introduced by Sun Microsystems in March 1994. It is based on the sun4m architecture, and is enclosed in a pizza box form factor, pizza-box chassis. Sun also offered a SPARCserver 5 without a framebuffer. A simplified, cheaper version of the SS5 was released in February 1995 as the SPARCstation 4. Sun also marketed these same machines under the "Netra" brand, without framebuffers or keyboards and preconfigured with all the requisite software to be used as web servers. An estimated 400,000+ SPARCstation 5s were sold. Specifications Release Price Sun rolled out the SPARCstation 5 for .

Peripheral Component Interconnect
Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus and are assigned addresses in the processor's address space. It is a parallel bus, synchronous to a single bus clock. Attached devices can take either the form of an integrated circuit fitted onto the motherboard (called a ''planar device'' in the PCI specification) or an expansion card that fits into a slot. The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of several slow Industry Standard Architecture (ISA) slots and one fast VESA Local Bus (VLB) slot as the bus configuration. It has subsequently been adopted for other computer types. Typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LSI Logic
LSI Logic Corporation, an American company founded in Milpitas, California, was a pioneer in the ASIC and EDA industries. It evolved over time to design and sell semiconductors and software that accelerated storage and networking in data centers, mobile networks and client computing. On May 6, 2014, LSI Corporation was acquired by Avago Technologies (now known as Broadcom Inc.) for $6.6 billion. History 1981–2004 In 1981, Wilfred Corrigan, Bill O'Meara, Rob Walker and Mitchell "Mick" Bohn founded LSI Logic Corporation in Milpitas, California. Wilfred Corrigan served as the CEO from 1981 until 2005. LSI was initially funded by venture capitalists, including Sequoia Capital, with $6 million. A second round of funding from Sequoia Capital as well as a number of companies from England came In March 1982, bringing in another $16 million. The initial plan called for a line of CMOS gate arrays created from “masterslices” which were uncommitted transistors customized to a speci ...

JavaStation
The JavaStation was a Network Computer (NC) developed by Sun Microsystems between 1996 and 2000, intended to run only Java applications. The hardware is based on the design of the Sun SPARCstation series, a very successful line of UNIX workstations. The JavaStation, as an NC, lacks a hard drive, floppy or CD-ROM drive. It also differs from other Sun systems in having PS/2 keyboard and mouse interfaces and a VGA monitor connector. Models There were several models of the JavaStation produced, some being pre-production variants produced in very small numbers. Production models comprised: * JavaStation-1 (part number JJ-xx), codenamed ''Mr. Coffee'': based on a 110 MHz MicroSPARC IIe CPU, this was housed in a cuboidal Sun "unidisk" enclosure. * JavaStation-NC or JavaStation-10 (part number JK-xx) codenamed ''Krups'': a redesigned ''Mr. Coffee'' with a 100 MHz MicroSPARC IIep CPU and enhanced video resolution and color capabilities. ''Krups'' was housed in a striking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
