_AddSatInt (Windows Embedded CE 6.0)

1/5/2010

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.
