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

FactSnippet No. 1,598,861

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

FactSnippet No. 1,598,862

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

FactSnippet No. 1,598,863

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

FactSnippet No. 1,598,864

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

FactSnippet No. 1,598,865

Higher-performance designs, such as the ARM chips9, have deeper pipelines: Cortex-A8 has thirteen stages.
