Knowra ARM architecture family ARM architecture family ARM is a family of processor architectures built around the Arm instruction set. Its designs span power-efficient mobile and embedded chips as well as processors for servers and other systems.
Arm instruction set : The defined machine instructions and architectural rules implemented by Arm-compatible processors. It specifies the operations that software can ask an Arm processor to perform.
Arm Cortex-A : A family of Arm processor cores designed for application processors running feature-rich operating systems. Cortex-A cores implement Arm architecture for phones, tablets, and other high-performance systems.
Smartphone : A mobile phone that combines cellular communication with general-purpose computing and applications. Arm processors became the standard foundation for most smartphone application processors.
x86 : A family of instruction set architectures originating with Intel's 8086 processor. x86 is the main competing architecture in personal computers and many server markets.
Acorn Computers : A British computer company that developed the BBC Micro and helped create the original Arm processor. Acorn's need for an efficient processor initiated the project that became Arm.
Reduced instruction set computer : A processor design approach emphasizing relatively simple instructions and efficient execution. Arm is historically associated with this design approach, though modern implementations are complex.
Arm Cortex-M : A family of small Arm processor cores designed for microcontrollers and embedded control. Cortex-M adapts Arm architecture to low-cost, low-power control devices.
Microcontroller : A compact computer on a chip, typically combining a processor, memory, and peripheral interfaces. Arm cores power many microcontrollers used in appliances, vehicles, and industrial controls.
RISC-V : An open standard instruction set architecture based on reduced instruction set principles. RISC-V offers an open alternative to Arm's proprietary architecture and licensing.
ARM1 : The first Arm processor prototype, completed in 1985 by Acorn's processor development team. ARM1 embodied the architecture's early design in working silicon.
