Advanced SIMD is a 64-bit and 128-bit hybrid Single Instruction Multiple Data (SIMD) technology targeted at advanced media and signal processing applications and embedded processors.
Advanced SIMD is implemented as part of the ARM core, but has its own execution pipelines and a register bank that is distinct from the ARM core register bank.
Advanced SIMD instructions are available in both A32 and A64. The A64 Advanced SIMD instructions are based on those in A32. The main differences are the following:
