Arguments

a

256-bit integer source vector

b

128-bit integer source vector

offset

an integer value that represents the 128-bit offset where the insertion must start

Description

Performs an insertion of 128 bits of packed scalar integer values from the second source vector b, into a destination at a 128-bit offset specified by the offset parameter. The remaining portions of the destination are written by the corresponding elements of the first source vector a.
