Risc PC
Risc PC was a range of personal computers launched in 1994 by Acorn, replacing the Archimedes series. The machines use the Acorn developed ARM CPU and were thereby not IBM PC-compatible. At launch, the original Risc PC 600 model was fitted as standard with an ARM 610, a 32-bit RISC CPU with 4 KB of cache and clocked at 30 MHz. CPU technology advanced rapidly in this period though and within only two years a DEC StrongARM could be installed at 233 MHz which was around 8 times faster. The machines were supplied with the RISC OS operating system which has a windowed cooperative multi-tasking design. Unusually for a PC of the period the O/S was stored in ROM, which enabled a relatively fast boot time. In addition Acorn sold a Virtual PC package that permitted x86 applications to be run in a virtual machine, they also supported the development of an ARM Linux distribution, from 1996. In contrast to most contemporary IBM clones, the machines supported multiple p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ARM System–on–Chip Architecture
''ARM System-on-Chip Architecture'' is a book detailing the system on a chip ARM architecture, as a specific implementation of reduced instruction set computing. It was written by Steve Furber, who co-designed the ARM processor with Sophie Wilson. The book's content covers the architecture, assembly language programming, support mechanisms for high-level programming languages, the instruction set and the building of operating systems. The Thumb instruction set is also covered in detail. It has been cited in numerous academic papers, and has been recommended to those working in the development of embedded system An embedded system is a specialized 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.

ARM7500
ARM7 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use. The ARM7 core family consists of ARM700, ARM710, ARM7DI, ARM710a, ARM720T, ARM740T, ARM710T, ARM7TDMI, ARM7TDMI-S, ARM7EJ-S. The ARM7TDMI and ARM7TDMI-S were the most popular cores of the family. ARM7 cores were released from 1993 to 2001 and no longer recommended for new IC designs; newer alternatives are ARM Cortex-M cores. Overview This generation introduced the Thumb 16-bit instruction set providing improved code density compared to previous designs. The most widely used ARM7 designs implement the ARMv4T architecture, but some implement ARMv3 or ARMv5TEJ. ARM7TDMI has 37 registers (31 GPR and 6 SPR). All these designs use a Von Neumann architecture, thus the few versions containing a cache do not separate data and instruction caches. Some ARM7 cores are obsolete. One historically significant model, the ARM7DI"ARM7DI Data Sheet"; Document Number ARM DDI 0027D; Issued: De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System On Chip
A system on a chip (SoC) is an integrated circuit that combines most or all key components of a computer or electronic system onto a single microchip. Typically, an SoC includes a central processing unit (CPU) with memory, input/output, and data storage control functions, along with optional features like a graphics processing unit (GPU), Wi-Fi connectivity, and radio frequency processing. This high level of integration minimizes the need for separate, discrete components, thereby enhancing power efficiency and simplifying device design. High-performance SoCs are often paired with dedicated memory, such as LPDDR, and flash storage chips, such as eUFS or eMMC, which may be stacked directly on top of the SoC in a package-on-package (PoP) configuration or placed nearby on the motherboard. Some SoCs also operate alongside specialized chips, such as cellular modems. Fundamentally, SoCs integrate one or more processor cores with critical peripherals. This comprehensive integration ...

RISC OS
RISC OS () is an operating system designed to run on ARM architecture, ARM computers. Originally designed in 1987 by Acorn Computers of England, it was made for use in its new line of ARM-based Acorn Archimedes, Archimedes personal computers and was then shipped with other computers produced by the company. Despite the demise of Acorn, RISC OS continues to be developed today by the RISC OS Open community on version 5.0 of the system that was open sourced in 2018. RISC OS is a Modular programming, modular operating system and takes its name from the reduced instruction set computer (RISC) architecture it supports. It incorporates a graphical user interface and a windowing system. Between 1987 and 1998, RISC OS shipped with every ARM-based Acorn computer including the Archimedes line, Acorn's R line (with RISC iX as a dual-boot option), RiscPC, Acorn A7000, A7000, and prototype models such as the Acorn Acorn Computers#NewsPad, NewsPad and Phoebe (computer), Phoebe computer.

Asynchronous Transfer Mode
Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by the American National Standards Institute and International Telecommunication Union Telecommunication Standardization Sector (ITU-T, formerly CCITT) for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and Real-time computing, real-time, low-latency content such as telephony (voice) and video.ATM Forum, The User Network Interface (UNI), v. 3.1, , Prentice Hall PTR, 1995, page 2. ATM is a cell switching technology, providing functionality that combines features of circuit switching and packet switching networks by using asynchronous communication, asynchronous time-division multiplexing.McDysan (1999), p. 287. ATM was seen in the 1990s as a competitor to Ethernet and networ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn User
''Acorn User'' magazine was founded by Acorn Computers in 1982, contract-published by Addison-Wesley, to coincide with the launch of the BBC Micro. It covered the range of Acorn home computers, the BBC Micro and Atom at first and later the Electron, Archimedes and Risc PC. History The first issue was dated July/August 1982. From the April 1984 issue, the magazine came under the control of Redwood Publishing, a company recently founded by Michael Potter (a former publisher at Haymarket Publishing), Christopher Ward (a former editor of the ''Daily Express'' and a non-executive director of Acorn) and Chris Curry (one of the founders of Acorn). In 1989, the name changed to ''BBC Acorn User'', reflecting the fact that the commercial arm of the BBC, BBC Enterprises, took control of Redwood to expand its publishing activities. The magazine lost the BBC branding when it was sold to Europress, publisher of rival title '' Acorn Computing'', coinciding with its January 1994 issue. The ma ...

Trade Show
A trade show, also known as trade fair, trade exhibition, or trade exposition, is an exhibition organized so that companies in a specific industry can showcase and demonstrate their latest products and services, meet with industry partners and customers, study activities of competitors, and examine recent market trends and opportunities. In contrast to consumer shows, only some trade shows are open to the public, while others can only be attended by company representatives (members of the trade, e.g. professionals) and members of the press, therefore trade shows are classified as either "public" or "trade only". A few shows are hybrids of the two; one example is the Frankfurt Book Fair, which is trade only for its first three days and open to the general public on its final two days. They are held on a continuing basis in virtually all markets and normally attract companies from around the globe. For example, in the U.S., there are currently over 10,000 trade shows held every ...
