NEON-Advanced SIMD vs. SIMD

Hello,

I’m new to ARM architecture and was looking to get a better understanding of how it works. Most notably, the Cortex-A series and its DSP functionality.

When reading through ARM’s webpage, it often refers to “NEON-Advanced SIMD”, “NEON”, and “SIMD” capabilities. Looking at the ARM processor architecture, it looks like SIMD is applied to ARMv6 architecture and NEON-Advanced SIMD is applied to ARMv7 architecture. From what I understand, NEON is an improved version of SIMD instruction used in ARMv6. If that is true, does this mean “NEON-Advanced SIMD” includes all the features of the previous SIMD included in ARMv6, such as the SIMD and DSP extensions? Or is it a different entity in its own?

Regards,

Kenrick
