There are different architectures to describe the Forward-Backward algorithm. These architectures can be different according to several criteria. If it is the first time you visit the site, I advise you to read the readme.txt. This file explains the architecture names that you can choose bellow. Furthermore, for each architecture, there is an explication of the decoding process (The encoding process is not explained because it can be easily understood thanks to the comments inside the programs).

Notice:

• Na is the number of Forward Recursion units
• Nb is the number of Backward Recursion units
• M is the memory type
• Pt and type define respectivly the number and the type of used pointers.

1. Architecture Na=1, Nb=2, M=0
   
   • main.
   • fonctions.c.
   • fonctions.h.
   • makefile.


2. Architecture Na=1, Nb=2, M=1
   
   • main.
   • fonctions.c.
   • fonctions.h.
   • makefile.


3. Architecture Na=1, Nb=3, M=0, Pt=3, Type=1
   
   • main .
   • fonctions.c .
   • fonctions.h .
   • makefile.
