_SmulAddHi_SW_SL

  • 项目

An ARM DSP-enhanced, signed-integer multiply-accumulate operation that multiplies the top half of register Rm and the top half of register Rs, producing a 32-bit product. The operation then performs a 32-bit accumulation with Rn.

int _SmulAddHi_SW_SL(
  int Arg1, 
  int Arg2,
  int Arg3
);

Parameters

  • Arg1
    The contents of Rn, the value added to the product of Arg2 and Arg3.
  • Arg2
    [in] The contents of Rm, the first term multiplied
  • Arg3
    [in] The contents of Rs, the second term multiplied.

Return Values

The result of the multiplication and accumulation.

Remarks

The compiler translates this instruction into the smlatt assembly instruction.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Armintr.h.
