ARM the Design became 1983 of the English computer manufacturer Acorn of computerLtd. as development project started. The team, under the direction of Roger Wilson and Steve Furber, began the development of an efficient processor for a successor up to then of the computers which are based on that 6502.
Instead of, to fall back as the competition, to processors of the companies Intel or Motorola,developed one its own processor, the ARM (Acorn Risc Machine), with 32 bits and a planned clock frequency of 4 MHz. The tests with the prototypes in such a manner successfully ran that the later series processors (ARM2), which were blocked in the again developed computers (Acorn Archimedes),directly with 8 MHz were clocked. Tests resulted in that these computers were about eight times faster with practically same clock frequency than the competitors Commodore Amiga and Atari pc.
After the ARM2 1989 to the ARM3 (with Cache and higher clock frequency) developed further was and ever moreCompanies interest in these processors had stated, created Acorn in the year 1990 together with Apple and VLSI Technology the company Advanced RISC Machines Ltd. (ARM) with seat in Great Britain.
the partial marks itself characteristics architecture by an efficient command sentence out,the 6502, permits a compact conversion in a ASIC is ajar - Design and is well suitable for optimizations in the range of the remark speed and the power input. An important implementation is the microprocessor well-known as StrongARM.
The manufacturer Intel is beside other market participants licensee of the company AdvancedRISC Machines Ltd. and may thus on arm architecture which am based processors manufacture. In addition Intel may (beside e.g.Motorola/Freescale or Philips), contrary to which most other licensees, changes and extensions at the ARM accomplish core. Thus Intel under the name XScale drives one outunder license manufactured arm CCU and further likewise than XScale designated and by bus tied up periphery semiconductors.
due to its low capacity arm processors come into many Embedded systems, like mobile telephones, PDAs and routing to the employment, e.g. in iPod of Apple or the newer PDAs of ASUS. The computers of the Acorn Archimedes and Risc PC - likewise arm CCUs used row of Acorn. Successors of these Desktop computers are among other things of the company CastleTechnology under the name IYONIX PC available.
