_SmulAddLo_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 bottom half of register Rm and the bottom half of Rs. This is followed with a 64 bit accumulate with the 32-bit registers RdLo and RdHi.
__int64 _SmulAddLo_SW_SQ(__int64Arg1,intArg2,intArg3);
Parameters
- Arg1
A pointer to a 64-bit variable used to accumulate the contents of 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 result of multiplication and accumulation.
Remarks
The compiler translates this instruction into the smlalbb assembly instruction.
