The ARM v8-A architecture provides load/store non-temporal pair instructions (LDNP/STNP) that provide a hint to the memory system that an access is non-temporal or streaming, and unlikely to be repeated in the near future. 也就是说在ARM v8-A架构里面LDNP/STNP指令是non-temporal的,也就是...
A load to the pc causes a branch to the instruction at the address loaded. In ARMv4, bits[1:0] of the address loaded must be 0b00. In ARMv5T and above: •bits[1:0] must not be 0b10 •if bit[0] is 1, execution continues in Thumb state •if bit[0] is 0, execution ...

This manual documents a substantially reduced version of the ARMv7 Microcontroller profile. This architecture variant aligns strongly with the ARMv6 Thumb instruction set and is known as ARMv6-M.
