This ARM DSP-enhanced, signed-integer multiply-accumulate operation multiplies the bottom half of register Rm and the bottom half of register Rs, producing a 32-bit product. The operation then performs a 32-bit accumulation with Rn.

int_SmulAddLo_SW_SL(intArg1,intArg2,intArg3);

Parameters

  • Arg1
    Contents of Rn, the value added to the product of Arg2 and Arg3.
  • Arg2
