Acorn (or later Advanced) RISC Machine (ARM) uses a 32-bit RISC (reduced instruction set computing) processor architecture that is utilized within many different applications. ARM processors are widely circulated, since their design integrates novel power-saving consumption and high performance features that adapt as part of the application design.


These chips or this technology, in particular, is used by multiple manufacturers to develop specialized microprocessors. "The ARM chip has become one of the most used CPU designs in the world, found in everything from hard drives, to mobile phones, to routers, to calculators, to children's toys. Today it accounts for over 75% of all 32-bit embedded CPU's" ("ARM Processing", np). Prominent companies using this technology include: Texas Instruments, Nintendo, Philips, Sharp, and IBM.
These devices usually include a one time use, in-order RISC processors that have little cache. It maybe sold as a generic chip or with a customized pre-programmed layout. Their real-world applications require they be small, efficient, and pre-screened to be correct for the equipment in which they are installed. They can be custom-designed, but the most important features are performance, power allocation, and cost. The specifications includes a load store architecture, 16 registers (some for general purpose and others for a program counter), 32-bit architecture and 32-bit instructions, with all instructions assured to meet quality standards. This is known as predicated.
The ARM processor has evolved from its humble beginnings in the early 1980s. ...
