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.

Syntax

int _SmulWLo_SW_SL(
  int Arg1, 
  int Arg2
);

Parameters

  • Arg1
    [in] The contents of Rm, the first term in the product.
  • Arg2
    [in] The contents of Rs, the second term in the product.

Return Values

The integer result of the multiplication and accumulation.

Remarks

The compiler translates this instruction into the smlawb assembly instruction.

Requirements

Architecture ARM10, ARM-DSP
Header armintr.h
Routine _SmulWLo_SW_SL
