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

FactSnippet No. 1,604,153

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

FactSnippet No. 1,604,154

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

FactSnippet No. 1,604,155

Higher-performance designs, such as the ARM architecture9, have deeper pipelines: Cortex-A8 has thirteen stages.

FactSnippet No. 1,604,156

The difference between the ARM architecture7DI and ARM architecture7DMI cores, for example, was an improved multiplier; hence the added "M".

ARM architecture provides a non-intrusive way of extending the instruction set using "coprocessors" that can be addressed using MCR, MRC, MRRC, MCRR, and similar instructions.

ARMv7 architecture defines basic debug facilities at an architectural level.

FactSnippet No. 1,604,159

The space saving comes from making some of the instruction operands implicit and limiting the number of possibilities compared to the ARM architecture instructions executed in the ARM architecture instruction set state.

FactSnippet No. 1,604,160

The VFP ARM architecture was intended to support execution of short "vector mode" instructions but these operated on each vector element sequentially and thus did not offer the performance of true single instruction, multiple data vector parallelism.
