9/7/2007
This ARM DSP-enhanced operation performs a saturating add instruction. It adds registers Rm and Rn, and places the result in register Rd. It affects the sticky-overflow bit 'Q' if overflow occurs in the addition.
Syntax
int _AddSatInt(
int Arg1,
int Arg2
);
Parameters
- Arg1
[in] The contents of Rm, the first term in the sum.
- Arg2
[in] The contents of Rn, the second term in the sum.
Return Values
The result of the binary arithmetic.
Remarks
The compiler translates this instruction into the qadd assembly instruction.
