micro_compiler

Implementation in Java of a micro compiler including:

• Constant and variable declaration.
• Simple expressions.
• Assignment instruction.
• If-then-else condition.

---

The micro_compiler consists of 2 phases:

1. Analysis phase, which includes:
   • Lexical analysis, using a pre-defined regular grammar.
   • Syntax analysis, using a context-free grammar.
   • Semantic analysis, using syntax directed translation.
2. Code generation phase: which was integrated in the parser and generates a set of assembly code instructions.
