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

FactSnippet No. 1,583,862

ARM NEON 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 NEON architecture specifies several CPU modes, depending on the implemented architecture features.

FactSnippet No. 1,583,864

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

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

FactSnippet No. 1,583,866

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

FactSnippet No. 1,583,867

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

FactSnippet No. 1,583,868

Higher-performance designs, such as the ARM NEON9, have deeper pipelines: Cortex-A8 has thirteen stages.

ARM NEON 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.

FactSnippet No. 1,583,871

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

FactSnippet No. 1,583,872

Some devices such as the ARM NEON Cortex-A8 have a cut-down VFPLite module instead of a full VFP module, and require roughly ten times more clock cycles per float operation.
