Architecture
From 1995, the ARM Architecture Reference Manual has been the primary source of documentation on the ARM processor architecture and instruction set, distinguishing interfaces that all ARM processors are required to support (such as instruction semantics) from implementation details that may vary. The architecture has evolved over time, and starting with the Cortex series of cores, three "profiles" are defined:
- "Application" profile: Cortex-A series
- "Real-time" profile: Cortex-R series
- "Microcontroller" profile: Cortex-M series.
Profiles are allowed to subset the architecture. For example, the ARMv6-M profile (used by the Cortex M0 / M0+ / M1) is a subset of the ARMv7-M profile (it supports fewer instructions).

Famous quotes containing the word architecture:
“No architecture is so haughty as that which is simple.”
—John Ruskin (1819–1900)
“The principle of the Gothic architecture is infinity made imaginable.”
—Samuel Taylor Coleridge (1772–1834)
“For it is not metres, but a metre-making argument, that makes a poem,—a thought so passionate and alive, that, like the spirit of a plant or an animal, it has an architecture of its own, and adorns nature with a new thing.”
—Ralph Waldo Emerson (1803–1882)
