SIMD (ARM NEON

A 128-bit SIMD architecture extension that accelerates multimedia and signal processing by executing operations on multiple data elements simultaneously.

NEON utilizes 32 64-bit registers (D0-D31) or 16 128-bit registers (Q0-Q15) to process data in parallel across ARMv7 and ARMv8 architectures. It handles 8-bit, 16-bit, 32-bit, and 64-bit integer and floating-point types (including half-precision). Developers leverage NEON for high-performance tasks like YUV-to-RGB conversion, FFT calculations, and matrix multiplication in neural networks. It is a standard feature on Cortex-A series processors, providing significant throughput gains for video encoding and real-time signal processing.
