Tadpole SPARCle
Tadpole Computer was a manufacturer of rugged, military specification, Unix, UNIX workstations, thin client laptops and lightweight servers. History Tadpole was founded in 1994 and originally based in Cambridge, England, then for a time in Cupertino, California. In 1998, Tadpole acquired RDI Computer Corporation of Carlsbad, California, who produced the competing RDI PowerLite, Britelite and Powerlite portable SPARC-based systems, for $6 million. Tadpole was later acquired by defense contractor General Dynamics, in April 2005. Production continued until March 2013 but since then, they no longer sell any systems; and support for their products is provided by Flextronics. An anonymous US intelligence officer had stated to Reuters in 2013 that a decade earlier the US secretly created a company Reseller, reselling laptops from Tadpole Computer to Asian governments. The reseller added secret software that allowed intelligence analysts to access the machines remotely. Products Tadp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PowerPC
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple Inc., Apple–IBM–Motorola alliance, known as AIM alliance, AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. Originally intended for personal computers, the architecture is well known for being used by Apple's desktop and laptop lines from 1994 until 2006, and in several videogame consoles including Microsoft's Xbox 360, Sony's PlayStation 3, and Nintendo's GameCube, Wii, and Wii U. PowerPC was also used for the Curiosity (rover), Curiosity and Perseverance (rover), Perseverance rovers on Mars and a variety of satellites. It has since become a niche architecture for personal computers, particularly with A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Computers
This article specifically addresses U.S. armed forces military computers and their use. History Some of the earliest computers were military computers. Military requirements for portability and ruggedness led to some of the earliest transistorized computers, such as the 1958 AN/USQ-17, the 1959 AN/MYK-1 (MOBIDIC), the 1960 M18 FADAC, and the 1962 D-17B; the earliest integrated-circuit based computer, the 1964 D-37C; as well as one of the earliest laptop computers, the 1982 Grid Compass. Military requirements for a computer small enough to fit through a submarine's hatch led to the AN/UYK-1. Construction Typically a military computer is much more robust than an industrial computer enclosure. Most electronics will be protected with a layer of conformal coating. There will be more structure inside to support the components, the plug-in cards will be individually supported and secured to assure they do not pop out of their sockets, the processor and heat sink will be secured, mem ...

Tadpole ALPHAbook 1
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians, such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been pres ...

UltraSPARC III
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. History When presented at the '97 Microprocessor Forum, the probable introduction date for the UltraSPARC III was 1999, and it would have competed with Digital Equipment Corporation's Alpha 21264 and Intel's Itanium (Merced). This was not to be the case as it was delayed until 2001. Despite being late, it was awarded the Analysts' Choice Award for Best Server/Workstation Processor of 2001 by ''Microprocessor Report'' for its multiprocessing features. Description The UltraSPARC III is an in-order superscalar microprocessor. The UltraSPARC III was designed for shared memory multiprocessing performance, and it has several features that ...

UltraSPARC IIe
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). Marc Tremblay was a co-microarchitect. Microarchitecture The UltraSPARC is a four-issue superscalar microprocessor that executes instructions in in-order. It includes a nine-stage integer pipeline. Functional units The execution units were simplified relative to the SuperSPARC to achieve higher clock frequencies - an example of a simplification is that the ALUs were not cascaded, unlike the SuperSPARC, to avoid restricting clock frequency. The integer register file has 32 64-bit entries. As the SPARC ISA uses register windows, of which the UltraSPARC has eight, the actual number of registers is 144. The register file has seven read and three write ports. The integer register file provides registers to two arithmetic logic units and the load ...
