IppStatus ippsMul_BNU4(const Ipp32u *a, const Ipp32u *b, Ipp32u *r);

a	Multiplicand, an integer big number of 4*32 bits.
w	Multiplier, an integer big number of 4*32 bits.
r	Multiplication result of 8*32 bits.

This function is declared in the ippcp.h file. The function multiplies two unsigned integers of 4*32 bit and returns the result of 8*32 bits.

The following pseudocode represents this function:

(*r) ← (*a) (*b).
