Downgrade from DM8168 to L138

Hi,

I have to downgrade a  DM8168 SW that runs on both ARM and DSP to L138. What are the things that are different and I need to be care of when porting from DM8168 to L138?

(1) The clock speeds are different;

(2) DM8168 supports SYSBIOS while L138 supports DSPBIOS;

(3) DM8168 supports DDR3 while L138 supports DDR2;

(4) DM8168 has some on chip memory while L138 does not (not sure ?);

What else?

Thanks,

Zhao
