_SmulWLo_SW_SL (Windows CE 5.0)
This ARM DSP-enhanced, signed-integer multiplication operation performs a 32x16 bit multiply on the 32-bit operand in Rm and the 16-bit source operand from the bottom half of register Rs. It then takes the upper 32 bits of the 48-bit product.
int _SmulWLo_SW_SL(int Arg1,int Arg2);
Parameters
- Arg1
