PortalPlayer, Inc.
PortalPlayer, Inc., founded in 1999, was a fabless semiconductor company that supplied system-on-a-chip semiconductors, firmware and software for personal media players. The company handled semiconductor design and firmware development, while subcontracting the actual semiconductor manufacturing to merchant foundries. It gained recognition as the company with which Apple contracted for development of the original iPod. The company went public with an IPO in November 2004 and traded on the NASDAQ under ticker symbol PLAY. Sales to Apple grew to 90% of the company's gross revenue, which ultimately hurt the company when Apple switched media processor chip vendors in its iPod lines. On January 5, 2007, Nvidia Corporation announced that it had acquired PortalPlayer, Inc. for about $357 million. Products PortalPlayer 5002 Dual ARM7TDMI cores with shared SRAM (3x 32KB banks). Errata in memory controller leads to halved data cache performance but fast SRAM. As the ARM7TDMI does ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiconductor
A semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be modified by adding impurities (" doping") to its crystal structure. When two regions with different doping levels are present in the same crystal, they form a semiconductor junction. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called " metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. Silicon is a critical element for fabricating most electronic circuits. Semiconductor devices can display a range of different useful properties, such as passing current more easil ...

EE Times
''EE Times'' (''Electronic Engineering Times'') is an electronics industry magazine published in the United States since 1972. EE Times is currently owned by AspenCore, a division of Arrow Electronics since August 2016. Ownership and status ''EE Times'' was launched in 1972 by Gerard G. Leeds of CMP Publications Inc. In 1999, the Leeds family sold CMP to United Business Media for $900 million. After 2000, ''EE Times'' moved more into web publishing. The shift in advertising from print to online began to accelerate in 2007, and the periodical shed staff to adjust to the downturn in revenue. In July 2013, the digital edition migrated to UBM TechWeb's DeusM community platform. On June 3, 2016, UBM announced that ''EE Times'', along with the rest of its electronics media portfolio ( EDN, Embedded.com, TechOnline, and Datasheets.com), was being sold to AspenCore Media, a company owned by Arrow Electronics, for $23.5 million. The acquisition was completed on August 1, 2016. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robe
A robe is a loose-fitting outer garment. Unlike garments described as capes or cloaks, robes usually have sleeves. The English word ''robe'' derives from Middle English ''robe'' ("garment"), borrowed from Old French ''robe'' ("booty, spoils"), itself taken from the Old Frankish">Frankish word *''rouba'' ("spoils, things stolen, clothes"), and is related to the word ''rob''. Types There are various types of robes, including: * A gown worn as part of the academic regalia of Faculty (teaching staff), faculty or students, especially for ceremonial occasions, such as a convocations, Wiktionary:congregation, congregations or graduations. * A gown worn as part of the attire of a judge or barrister. * A wide variety of long, flowing religious dress including pulpit robes and the robes worn by various types of monks. * A gown worn as part of the official dress of a peer or royalty. * Any of several women's fashions of French origin, as '' robe à l'anglaise'' (18th century), ...

String (computer Science)
In computer programming, a string is traditionally a sequence of character (computing), characters, either as a literal (computer programming), literal constant or as some kind of Variable (computer science), variable. The latter may allow its elements to be Immutable object, mutated and the length changed, or it may be fixed (after creation). A string is often implemented as an array data structure of bytes (or word (computer architecture), words) that stores a sequence of elements, typically characters, using some character encoding. More general, ''string'' may also denote a sequence (or List (abstract data type), list) of data other than just characters. Depending on the programming language and precise data type used, a variable (programming), variable declared to be a string may either cause storage in memory to be statically allocated for a predetermined maximum length or employ dynamic allocation to allow it to hold a variable number of elements. When a string appears lit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IPod Photo
The iPod Classic (stylized and marketed as iPod classic and originally simply iPod) is a discontinued portable media player created and formerly marketed by Apple Inc. There were six generations of the iPod Classic, as well as a spin-off (the iPod Photo) that was later re-integrated into the main iPod line. All generations used a hard drive for storage. The "classic" suffix was formally introduced with the rollout of the sixth-generation iPod on September 5, 2007. Prior to this, all iPod Classic models were simply referred to as iPods; the first iPod released in 2001 was part of this line that would be called "Classic". It was available in silver or black from 2007 onwards, replacing the "signature iPod white". On September 9, 2014, Apple discontinued the iPod Classic.

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary Processor (computing), processor in a given computer. Its electronic circuitry executes Instruction (computing), instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, CPU design, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic operation, arithmetic and Bitwise operation, logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the #Fetch, fetching (from memory), #Decode, decoding and ...

ARM Architecture
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer, RISC instruction set architectures (ISAs) for central processing unit, computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses semiconductor intellectual property core, cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktop computer, desktops and server (computing), servers, including Fugaku (supercomputer), Fugaku, the world's fastest supercomputer from 2020 to 2022.
