This directory contains a basic C compiler (BCC), developed as part of the
computer system course of the fourth year of computer and network studies at
INSA Toulouse.

This compiler supports a simplified syntax of the C language, including
mathematical operations, loops and functions. It makes it possible to produce
assembly code and/or a binary object executable by the associated FPGA. The
assembly instruction set used is specific to the project and is used by the
cross-assembler to produce the object code. The compiler is implemented in Lex,
Yacc and C; the cross-assembler is developed in Python. The cross-assembler also
performs code optimization operations in two passes and allows the use of
registers. An interpreter is available to execute the assembly code produced by
the compiler. A limited management of errors is also implemented, allowing a 
verbose output in most error cases.

To get started and compile one of the examples (see Makefile and examples/),
use:

$ make example

To compile a given source file use:

$ make
$ ./bcc <source_file>
$ ./ca.py <asm_file>

You can also use the given interpreter to run the compiled assembly code:

$ make demo

To test the error detection, use:

$ make error

The vhdl/ folder contains all the source code used on the target FPGA. This part
is independent of the compiler itself, but is the main target for the compiler.
