I am currently in the phase of looking at architectures or better
architectural features that are currently available and what compilers
and compiler environments do currently exist and how they are able to
address all this features. So to be more precise I am currently
analyzing the requirements.


What I found out so far is that based on our LISA description it is
possible to address all sorts of instruction set architectures for
simulator, assembler, linker and even the VHDL-controll path
generation: general purpose CPUs, DSPs, Microcontrollers with all
their features.


This seems to be no longer true for the compiler environment. What I
am looking for is a flexible, modular and fast way for someone that
has done his architecture description in LISA to come to a C-Compiler
for this architecture.


If you are interested I want to invite you to look at our LISA
homepage at: http://www.iss.rwth-aachen.de/lisa The LISA manual is
downloadable from this page. It explains how an architecture is
described and how the tools are retargeted by the description. The
description of the DLX architecture is given as an example.
