6809 to 8051 assembly language converter

I have a potential customer that is interested in porting a 6809 application to the 8051. His 6809 code is all assembly. Does anyone know of any tools that can help him do this?

  • This will not be an exercise that deserves the name "porting". It's called "re-inventing the wheel" or "rewrite from scratch". The only tool I know that can do it is called a human brain, and it's quite expensive to use.

    I.e. you'll have to almost completely ignore that that you have the 6809 code, and start writing new code for the 8051 from scratch.

    To explain this in more figurative terms: what you want to do is turn a beef burger into chicken burger, and that simply won't work. You'll have to follow the processing chain of the beef burger all the way back to the ranch where the cattle was living and convince the rancher to raise chickens instead. Needless to say, you're gonna have lots of resistance to overcome doing this.
