To both AArch32 and AArch64, Armv8-A makes VFPv3/v4 and advanced SIMD (Neon) standard. It also adds cryptography instructions supporting AES, SHA-1/SHA-256 and finite field arithmetic. AArch64 was introduced in Armv8-A and its subsequent revision. AArch64 is not included in the 32-bit Armv8-R and Armv8-M architectures.
