Performs packed move with sign-extend on 8-bit signed integers to 16/32/64-bit integers. The corresponding Intel® AVX2 instruction is
- 128-bit integer source vector used for the operation
Performs a packed move with sign-extend operation to convert 8-bit [byte] integers in the low bytes of the source vector,
s1, to 16-bit [word], 32-bit [doubleword], or 64-bit [quadword] integers, which are stored as packed signed word/doubleword/quadword integers in the destination vector.
Result of the sign-extend operation.
