How to compile C51 assembly code for C55 ?

I am looking for any assembly language differences(between C55 and C51) or ways that C55 compiler can understand assembly code written for C51 processor. 

Any info is helpful.

Thank you.

    This processor is several generations old.  You would be much better off starting the design from scratch, and implementing in C, than trying to drag this implementation along.  Not only is the instruction set different, but the peripherals will have different behavior as well.
