ARM family cores are used in a number of products, particularly PDAs and smartphones.

FactSnippet No. 1,645,904

ARM family chips are used in Raspberry Pi, BeagleBoard, BeagleBone, PandaBoard, and other single-board computers, because they are very small, inexpensive, and consume very little power.

Except in the M-profile, the 32-bit ARM family architecture specifies several CPU modes, depending on the implemented architecture features.

FactSnippet No. 1,645,906

Original ARM family implementation was hardwired without microcode, like the much simpler 8-bit 6502 processor used in prior Acorn microcomputers.

FactSnippet No. 1,645,907

ARM family includes integer arithmetic operations for add, subtract, and multiply; some versions of the architecture support divide operations.

FactSnippet No. 1,645,908

Almost every ARM family instruction has a conditional execution feature called predication, which is implemented with a 4-bit condition code selector.

FactSnippet No. 1,645,909

ARM family processor has features rarely seen in other RISC architectures, such as PC-relative addressing and pre- and post-increment addressing modes.

FactSnippet No. 1,645,910

Higher-performance designs, such as the ARM family9, have deeper pipelines: Cortex-A8 has thirteen stages.
