hi all,

I ve one old board with NEC78C18 which is now obsolete. I ve software for i in assembly.

I want to port that code to NEC's 78KE2 series controller or Renesas H8/36084 controller. But few instructions are not compatible. Also Renesas doenot suggest any direct replacement for 78C18.

How this porting can be done in less time? Is there any tool like code parser or converter for such thing?
 

Porting the assembly code on different instruction set can't be done automatically, you need to understand existing code and re-implement everything. That's the reason people are using high-level languages like C more and more.
