Use of intrinsic for SC3400 core

I am looking is the intrinsics which can help me in finding result cross product of two complex no and give me real and imag part in 32 bit registers. I require this for SC3400 core. For the TI processor the intrinsic available for this type of computation are _mpyh,_mpylh,_mpy and _mpyhl.

Now acc to AN3434.pdf it says the equivalent to those TI intrinsic are V_L_mult_ll , V_L_mult_lh V_L_mult_hh and V_L_mult_hl But when i use this intrinsic it gives me the reult which is scaled by 2. IS I am missing something or doing something wrong.

Can some one please point out this.

Regards Deepak
