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 top half of register Rs. It then takes the upper 32 bits of the 48-bit product.
Syntax
int _SmulWHi_SW_SL(
int Arg1,
int Arg2
);
Parameters
- Arg1
[in] The first term in the product, the contents of Rm.
- Arg2
[in] The second term in the product | the contents of Rs.
Return Values
The integer result of the multiplication.
Remarks
The compiler translates this instruction into the smulwt assembly instruction.
Requirements
| Architecture | ARM10, ARM-DSP |
| Header | armintr.h |
| Routine | _SmulWHi_SW_SL |
