Use tombstone notation. If your solution would require a particular thing to be coded, explain why and diagram it. You cannot assume you will be able to buy something.

You have machine M, and executable binaries for a C->M host compiler. You also have the source for Pascal->C compiler in C. Show what you have with tombstone diagrams

You write an application Prj in C. Show all steps until generative execution.

Redo showing all steps for interpretive execution (note you dont have an interpreter yet).

You then write the same application in Pascal. Show all that is needed for any execution.

After doing the above, you need to run both projects on small-resource machine N. Assuming that N is too small to run any translators, what you do? Show with diagrams.

Now your N is larger (maybe you bought more memory) and you can now start running compilation on N, and you want to implement a compiler somehow rather than buy (maybe no one sells compilers for N), what you do? Show all steps with diagrams.
