Synopsis
int __smuad(int16x2 val1,
int16x2 val2);
Description
__smuad inserts a SMUAD instruction. __smuad returns the equivalent of
- res = val1[0] * val2[0] + val1[1] * val2[1]
where [0] is the lower 16 bits and [1] is the upper 16 bits.
This operation sets the Q flag if overflow occurs on the addition.
