Generate C code for a topology

[hidmic]

Description

To actually use and validate an optimized LTI system, it has to be translated into code that can be assembled or compiled for a given processor architecture. C is by far the most common language for that purpose. Thus, putting all together, ltitop must support C code generation for a given realization or diagram.

Definition of Done

In the following, it is assumed that #9 was implemented.

• Write a function to extract a Python AST for an entire diagram.
  • Collate block ASTs as function definitions.
  • Drop repeated function definitions.
  • Capture block connections via function calls.
• Write a function to transform a Python AST into a pycparse C-AST.
  • Use an ast.NodeTransformer subclass.
• Use pycparse.c_generator.CGenerator to generate C code.
  • Toss in all necessary C preprocessor directives for compilation.
