Castle Technology
Castle Technology Limited, named after Framlingham Castle, was a British computer company based in Cambridge, England. It began as a producer of ARM computers and manufactured the Acorn-branded range of desktop computers that run RISC OS. Following the break-up of Acorn in 1998, Castle Technology bought the rights to continue production of the RISC PC and A7000+ computers under the Acorn brand. Castle Technology later released the Iyonix PC in November 2002, the first desktop computer to use the Intel XScale microarchitecture and then bought the rights to the RISC OS Technology from Pace in July 2003. History After Acorn withdrew from the desktop computer industry in 1998, Castle Technology acquired the rights to produce the A7000, A7000+ and RISC PC using the ''Acorn'' brand. In 2001, development started on the Iyonix PC (codenamed ''Tungsten'') as a set-top unit (STU) in secret by engineers at Pace's Shipley campus along with a 32-bit version of RISC OS 4 (know ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Times Educational Supplement
''Tes'', formerly known as the ''Times Educational Supplement'', is a weekly UK publication aimed at education professionals. It was first published in 1910 as a pull-out supplement in ''The Times'' newspaper. Such was its popularity that in 1914, the supplement became a separate publication selling for one penny. ''TES'' focuses on school-related news and features. It covered higher education until the ''Times Higher Education Supplement'' (now ''Times Higher Education'') was launched as a sister publication in 1971. Today its editor is Jon Severs. Since 1964, an alternative version of the publication, ''TESS'', has been produced for Scotland. An edition for Wales, ''TES Cymru'', was also published between 2004 and 2011. The lack of content about Wales since its closure has been criticised by the Welsh Education Minister, Jeremy Miles. All are produced by London-based company TES Global, which has been owned by US investment firm Providence Equity Partners LLC since 2018. The ...

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a ''sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agree ...

Restriction Of Hazardous Substances Directive
The Restriction of Hazardous Substances Directive 2002/95/EC (RoHS 1), short for Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment, was adopted in February 2003 by the European Union. The initiative was to prevent an overabundance of chemicals in electronics. Thus, as a result electronics were restricted. The RoHS 1 directive took effect on 1 July 2006, and is required to be enforced and became a law in each member state. This directive restricts (with exceptions) the use of ten hazardous materials in the manufacture of various types of electronic and electrical equipment. In addition to the exceptions, there are exclusions for products such as solar panels. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC (now superseded) which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of ...

Lead
Lead is a chemical element with the Symbol (chemistry), symbol Pb (from the Latin ) and atomic number 82. It is a heavy metals, heavy metal that is density, denser than most common materials. Lead is Mohs scale of mineral hardness#Intermediate hardness, soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
32-bit
In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32- bit units. Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle. Typical 32-bit personal computers also have a 32-bit address bus, permitting up to 4 GB of RAM to be accessed; far more than previous generations of system architecture allowed. 32-bit designs have been used since the earliest days of electronic computing, in experimental systems and then in large mainframe and minicomputer systems. The first hybrid 16/32-bit microprocessor, the Motorola 68000, was introduced in the late 1970s and used in systems such as the original Apple Macintosh. Fully 32-bit microprocessors such as the Motorola 68020 and Intel 80386 were launched in the early to mid 1980s and became dominant by the early 1990s. This generation of personal computers c ...

Set-top Box
A set-top box (STB), also colloquially known as a cable box and historically television decoder, is an information appliance device that generally contains a TV-tuner input and displays output to a television set and an external source of signal, turning the source signal into content in a form that can then be displayed on the television screen or other display device. They are used in cable television, satellite television, and over-the-air television systems as well as other uses. According to the ''Los Angeles Times'', the cost to a cable provider in the United States for a set-top box is between $150 for a basic box to $250 for a more sophisticated box. In 2016, the average pay-TV subscriber paid $231 per year to lease their set-top box from a cable service provider. TV signal sources The signal source might be an Ethernet cable, a satellite dish, a coaxial cable (see cable television), a telephone line (including DSL connections), broadband over power lines ( ...

Microarchitecture
In computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as µarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. A given ISA may be implemented with different microarchitectures; implementations may vary due to different goals of a given design or due to shifts in technology. Computer architecture is the combination of microarchitecture and instruction set architecture. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the instructions, execution model, processor registers, address and data formats among other things. The microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XScale
XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture (version 5) instruction set. XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE (see more below), with some later models designed as system-on-a-chip (SoC). Intel sold the PXA family to Marvell Technology Group in June 2006. Marvell then extended the brand to include processors with other microarchitectures, like ARM's Cortex. The XScale architecture is based on the ARMv5TE ISA without the floating-point instructions. XScale uses a seven-stage integer and an eight-stage memory super- pipelined microarchitecture. It is the successor to the Intel StrongARM line of microprocessors and microcontrollers, which Intel acquired from DEC's Digital Semiconductor division as part of a settlement of a lawsuit between the two companies. Intel used the StrongARM to replace its ailing line of outdated RISC processors, the i860 and i960. All the generation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
