How to develop compiler without compiler writing tools

My teacher gave this question ( how to develop compilers without compiler writing tools ). I searched for it but I did not find anything. So, If anyone have any idea about this please help me. I found so many information about developing compiler with writing tools but I found nothing when I searched for without compiler writing tools.

Thank you in advance.

A compiler is basically a filter/converter. It reads text files and outputs data that happens to be identical to the instructions the given CPU understands.

So you need to find out:

  • what assembler code your source language‘s commands are equivalent to
  • what byte sequences each of these assembler commands are equivalent to

Then you can read the source file and output compiled code.
