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:
“I don’t think of form as a kind of architecture. The architecture is the result of the forming. It is the kinesthetic and visual sense of position and wholeness that puts the thing into the realm of art.”
—Roy Lichtenstein (b. 1923)
“Art is a jealous mistress, and, if a man have a genius for painting, poetry, music, architecture or philosophy, he makes a bad husband and an ill provider.”
—Ralph Waldo Emerson (1803–1882)
“It seems a fantastic paradox, but it is nevertheless a most important truth, that no architecture can be truly noble which is not imperfect.”
—John Ruskin (1819–1900)
