A retargetable compiler

Hello!


        I am a student of Electronic Engineering in the UPC (Polytechnic
University of Catalonian), and I am making the final working. I have
some problems and I would be very thank to you if somebody can help
me!


        I am making a parametrizable processor (with the philosophy of a
reconfigurable computer) in a Xilinx FPGA, with VHDL. It is Harvard
architecture and it has variable data wide [N bits] and variable
instruction wide [P+16 bits](and so variable addressing space for data
and instructions [2expP+16]).


        But we want that it could be programmed in anything more that
assembler, so we are trying to make a compiler. We have found
information about retargetable compilers like LANCE, that let have
source code in ANSI C and has all the work of analysis made, it is
architecture independent.


        In LANCE documentation speaks about the tools OLIVE and IBURG for
make the synthesis, the code generators. I have found IBURG, but I
found nothing about OLIVE.


        Could you tell me where can I found it?


        And, more general, do you thing those are the right tools I need?
Where can I found more documentation about how to use them?


        Well, thank you very much! Oh, and sorry for my horrible English!
