Vector Signed Dot Product and Add
The signed integer elements in vector b
(four signed 32-bit integer numbers)
are multiplied by signed integer elements in vector c
(four signed 32-bit integer numbers)
producing a result twice the size of the input operands. The multiplication results
of adjacent odd/even elements are added to the vector a
(two signed 64-bit integer numbers).
