Pack with rounding shift

Pack values from two vectors to one with rounding shift

Values from the input vectors will be shifted right by n bits with rounding, converted to narrower type and returned in the result vector. Variant with u suffix converts to unsigned type.

  • pack: for 16-, 32- and 64-bit integer input types
  • pack_u: for 16- and 32-bit signed integer input types
Note
All variants except 64-bit use saturation.

Pack and store

Store values from the input vector into memory with pack

Values will be stored into memory with conversion to narrower type. Variant with u suffix converts to corresponding unsigned type.

  • pack: for 16-, 32- and 64-bit integer input types
  • pack_u: for 16- and 32-bit signed integer input types
Note
All variants except 64-bit use saturation.

Pack boolean values
