LDNT1W (scalar plus immediate, single register) Contiguous load non-temporal words to vector (immediate index) Contiguous load non-temporal of words to elements of a vector register from the memory address generated by a 64-bit scalar base and immediate index in the range -8 to 7 which is multiplied by the vector's in-memory size, irrespective of predication, and added to the base address. Inactive elements will not cause a read from Device memory or signal a fault, and are set to zero in the destination vector. A non-temporal load is a hint to the system that this data is unlikely to be referenced again soon.
