This function multiplies the two 32-bit inputs, x and y, and accumulates
the product with prod. The function takes care of saturating the result
in case of underflow or overflow.
<libq.h>
_Q16 _Q16mac(_Q16x, _Q16 y, _Q16 prod);
x
ranges from -2147483648 to 2147483647.
y
ranges from -2147483648 to 2147483647.
prod
ranges from -2147483648 to 2147483647.
This function returns the multiplied and accumulated value prod in
Q16 format. This value ranges from 0 to 2147483647.
This function multiplies the two 32 bit inputs, x and y and accumulates
the product with prod.This function only sets the _Q16macSatFlag
variable in case of an overflow or underflow and does not take care of
saturation.
<libq.h>
_Q16 _Q16macNoSat(_Q16 x, _Q16 y, _Q16 prod);
x
ranges from -2147483648 to 2147483647.
y
ranges from -2147483648 to 2147483647.
prod
ranges from -2147483648 to 2147483647.
This function returns the multiplied and accumulated value prod in
Q16 format. This value ranges from 0 to 2147483647.
This function negates x with saturation. The value is saturated in the
case where the input is -2147483648.
<libq.h>
_Q16 _Q16neg(_Q16 x);
x
ranges from -2147483648 to 2147483647.
This function returns the negated value of x in Q16 format. This value
ranges from -2147483648 to 2147483647.
