_SmulAddHi_SW_SQ (Windows CE 5.0)
This ARM DSP-enhanced, signed integer multiply-accumulate operation first performs a multiply on two 16-bit source operands from the top half of register Rm and the top half of Rs. This is followed with a 64 bit accumulate with the 32-bit registers RdLo and RdHi.
__int64 _SmulAddHi_SW_SQ(__int64Arg1,intArg2,intArg3);
Parameters
- Arg1
Pointers to a 64-bit accumulate that contains RdHi and RdLo. - Arg2
[in] The contents of Rm, the first term in the product. - Arg3
[in] The contents of Rs, the second term in the product.
Return Values
The long integer result of the multiplication and accumulation.
Remarks
The compiler translates this instruction into the smlaltt assembly instruction.
