s1 |
128-bit integer source vector used for the operation |
Performs a packed move with sign-extend operation to convert 16-bit [word] integers in the low bytes of the source vector, s1, to 32-bit [doubleword] or 64-bit [quadword] integers and stored as packed signed doubleword/quadword integers in the destination vector.
Result of the sign-extend operation.
