Acorn Archimedes Acorn Archimedes Fuelled by Acorns innovative ARM RISC processor, the Archimedes or A series offer workstation power and spectacular graphics abilities at PC prices. With their place in education already assured, Dick Pountain believes their speed may also guarantee them entry into the business world. 98 PCW AUGUST 1987 Ever since Acorn first announced the details of its ARM RISC processor chip it has been quite obvious, despite rather feeble denials from the company, that ARM was intended to power the successor to the venerable BBC Computer. ARMs designers quite openly stated their goal, which was to produce a 32bit replacement for the 6502, all the major competitors having been rejected as inadequate. When last year Acorn launched the Master, a slightly repackaged Beeb, it was received in the press with something approaching scorn, and many people expressed scepticism about whether Acorn had the wherewithall to do anything useful with ARM. With the launch of the Archimedes or ' A series of computers, we can see that the Master was merely a stopgap measure, and that behind the scenes One concession to industry standards is the Archimedes keyboard, which Aeorn was giving everything it had to offers both IBM PC and BBC Model B compatibility. Like the Model 300 it ARM technology. It has been well worth has red function keys, presumably to persuade BBC Model B owners to upgrade the wait. The A series machines offer to an Archimedes. A threebutton mouse is fitted as standard workstation power at personal computer prices, and they deliver this power to the ecute in a single clock cycle. Like the old handle up to eight sound channels in programmer in an easytouse way, 6502 which partly inspired it, it gets its stereo. The sound generation facility resulting in truly spectacular graphics speed from short instructions rather than provided is rather simple compared with abilities. fast clocks (the 4MHz clock yields roughly dedicated synthesiser chips like the It would be as well to clarify the status four MIPS).

One of the most striking aspects of the new RISC PC is its case, designed under the auspices of Allen Boothroyd, who designed the original BBC Micro and was a force behind hi-fi manufacturer Meridian. It is made of tough Bayer Bayblend ABS/Polycarbonate, which is used to make riot shields. Internal surfaces are coated to reduce radio frequency interference (RFI) but the external surface is an unpainted light grey. There is provision for screw-mounted peripherals inside but devices like CD-ROMs and hard disks will be clip-mounted Apple-style. Two twist-locking pins need to be turned 90° to get the case lid off. These can be padlocked and the case tethered. It takes less than a minute to open the case, swap processor modules and refit the lid, without any tools.

  • Updated Virtualrpc Components for RISC OS 6
    ne of the main things that keeps me using my Risc PC is the versatility of the operating system - mainly due to it’s universal draw file format. For Oinstance I construct the centre pages in Artworks as this now has excellent PDF export facilities. However for proofing the magazine before it gets sent to the printers I like to do a printout to see if everything works properly. Because Artworks now can deal with multiple pages it is very easy to save each page either as an Artworks file or Draw file directly into the magazine’s Ovation Pro file by dragging and dropping. A two second job! Other computer platforms don’t generally have this facility of moving files directly into open application windows. Generally to move a file to another application you have to use the dreaded ‘save as’ filer window - choose a suitable format - navigate to where you need to save the file - save it - go to the other application - open a filer window - navigate to the saved file - open it in the new application. If you need to transfer a different file type you generally have to go through all that palaver again. Two seconds on RISC OS, thirty seconds on OS X or Windows. Draw is a great program with no real equivalent on a PC or Mac. For instance it can be put to good use in music for constructing objects the original program can’t do. I use the Sibelius music setting program on both RISC OS and Windows. The RISC OS still has one or two advantages over the PC version, one of which is it’s ability to export to Draw.

  • Acorn Springboard
    Acorn Springboard Powered by Acorns innovative ARM RISC processor, the Springboard coprocessor board turns your PC into a very powerful workstation, albeit minus the stunning graphics. Such numbercrunching power doesnt come cheap, however, as Dick Pountain discovered. The Acorn Springboard is a coprocessor board for IBM PC compatibles, powered by an Acorn ARM RISC processor. It contains either 1 or 4Mbytes of memory and communicates with the host PC through Acorns Tube parallel interface, originally developed on the BBC Micro. The Springboard is a selfcontained computer and can run programs quite independently of the host PC; this enables dual tasking, where the user runs an application on the PC while the Springboard runs its own program in the background. On the other hand, the Springboard Interface Software permits the board to swap data with the host PC using fast block transfers, to make DOS interrupt calls and use the host disks and filing system. The 8MHz ARM processor is one of the fastest microprocessors available today, capable of sustaining 4MIPS (million instructions per second). Adding a Springboard to a PC or AT gives you a workstation with computing power, for suitable tasks, that rivals that of a VAX control, which further reinforces this podule interface is not fast enough to support minicomputer. The sort of tasks that Acorn orientation toward the laboratory. the required level of VIDC/ MEMC has in mind for the Springboard are mainly One thing to be clear about right from the communication. If you need the graphics, buy numbercrunching ones, especially for start is that the Springboard will not turn your an Archimedes; Springboard is for CPU scientists and engineers; a Fortran compiler PC into an Acorn Archimedes, for the simple power only.

  • ACORN RISC MACHINE Jitendra Marathe ARM Is a Reduced
    SRJIS / BIMONTHLY/JITENDRA MARATHE. (581-585) ACORN RISC MACHINE Jitendra Marathe ARM is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by ARM Holdings. It was named the Advanced RISC Machine and, before that, the Acorn RISC Machine. The ARM architecture is the most widely used 32-bit instruction set architecture in numbers produced. Originally conceived by Acorn Computers for use in its personal computers, the first ARM-based products were the co-processor modules for the BBC series of computers. Features and applications: In 2005 about 98% of the more than one billion mobile phones sold each year used at least one ARM processor. As of 2009 ARM processors accounted for approximately 90% of all embedded 32-bit RISC processors and were used extensively in consumer electronics, including personal digital assistants (PDAs), tablets, mobile phones, digital media and music players, hand-held game consoles, calculators and computer peripherals such as hard drives and routers. Licensees: The ARM architecture is licensable. Companies that are current or former ARM licensees include Alcatel-Lucent, Apple Inc., AppliedMicro, Atmel, Broadcom, Cirrus Logic, CSR_plc, Digital Equipment Corporation, Ember, Energy Micro, Freescale, Intel (through DEC), LG, Marvell Technology Group, Microsemi, Microsoft, NEC, Nintendo, Nuvoton, Nvidia, Sony, NXP (formerly Philips Semiconductor), Oki, ON Semiconductor, Psion, Qualcomm, Renesas, Samsung, Sharp, Silicon Labs, STMicroelectronics, Symbios Logic, Texas Instruments, VLSI Technology, Yamaha, Fuzhou Rockchip, and ZiiLABS. In addition to the abstract architecture, ARM offers several microprocessor core designs, including the ARM7, ARM9, ARM11, Cortex- A8, Cortex-A9, and Cortex-A15. Companies often license these designs from ARM to manufacture and integrate into their own system on a chip (SoC) with other components like RAM, GPUs, or radio basebands (for mobile phones).

  • Arm System-On-Chip Architecture.Pdf
    Preface Aims This book introduces the concepts and methodologies employed in designing a system-on-chip (SoC) based around a microprocessor core and in designing the microprocessor core itself. The principles of microprocessor design are made con- crete by extensive illustrations based upon the ARM. The aim of the book is to assist the reader in understanding how SoCs and micro- processors are designed and used, and why a modern processor is designed the way that it is. The reader who wishes to know only the general principles should find that the ARM illustrations add substance to issues which can otherwise appear somewhat ethereal; the reader who wishes to understand the design of the ARM should find that the general principles illuminate the rationale for the ARM being as it is. Other microprocessor architectures are not described in this book. The reader who wishes to make a comparative study of architectures will find the required informa- tion on the ARM here but must look elsewhere for information on other designs. Audience The book is intended to be of use to two distinct groups of readers: • Professional hardware and software engineers who are tasked with designing an SoC product which incorporates an ARM processor, or who are evaluating the ARM for a product, should find the book helpful in their duties. Although there is considerable overlap with ARM technical publications, this book provides a broader context with more background. It is not a substitute for the manufac turer's data, since much detail has had to be omitted, but it should be useful as an introductory overview and adjunct to that data.
