| The NEON allows the CPU to perform operations on multiple data items with a single instruction. Standard scalar instructions can handle only one scalar value in one register, but NEON registers are specially designed so that they can hold multiple values. And this is how Single Instruction, Multiple Data (SIMD) operations work: one instruction operating on several elements in parallel. This technique is widely used for image, signal, and multimedia processing, as well as for accelerating math-heavy tasks like machine learning, encryption or other Artificial Intelligence AI tasks. The processor used in the Raspberry Pi 5 supports the NEON and floating-point (FP) instruction sets. | The NEON allows the CPU to perform operations on multiple data items with a single instruction.
