VLSI DESIGN COURSE
(c) 1995 M. Gumm University of Stuttgart

This directory contains the source code and an allready compiled (SPARC)
version of the DLXS assembler "dlx_asm".

The original code belongs to the ALLIANCE suite of MASI/IBP/CAO_VLSI
laboratory in Paris.

This version is completely restructred and extended for the use within 
the VLSI Design Course. New features are:

 + DLX Assembler for all instructions (signed/unsigned/floating point) as
   defined by Hennessy/Patterson

 + DLX Instruction coding as defined by Hennessy/Patterson
 
 + Synthetic instructions

 + New behavioural VHDL description of the generated ROM unit
  
 
Type "dlx_asm" without any further parameters to get the small man page:

usage : dlx_asm <-s|u|i|f> <assembly_file> <vhdl_file_ext>
 
options:
 -s   include only signed integer instructions
 -u   include "-s"-instructions and instructions for unsigned
       integer operations except multipl. and division operators
 -i   include "-s" and "-u"-instructions and
       multiplication and division operators
 -f   include "-s" and "-u"and "-i"-instructions and
       all floating point instructions
 
example: dlx_asm -u test.asm test
   -> the input file "test.asm" is read
   -> instructions for unsigned integer operations are allowed
   -> the output file "rom-behaviour_test.vhd" is generated


Have fun !
