MMU for Leon project (16.12.2002-16.3.2003):
12.2002 - 03.2003, Gaisler Research-Project 
Leon is a Open Source processor maintained by Jiri Gaisler. For information on Leon go to Gaisler Research. Here you can download a vhdl design of a Memory Management Unit that I made in the course of my Diploma Thesis and reimplemented in a 3 month project funded by Jiri Gaisler. When sufficiently tested this source will be added to the official Leon source distribution. Therefore help testing!
In addition there is a port of linux-2.5.59 onto the Leon-architecture that I have been developing recently. Have fun and enjoy!
Attention: Linux port is still a work in process. You can eather run on hardware or, using Leon's mmu enabled tsim sparc-simulator, you can symbolically debug the linux kernel with gdb. A nice way to get familiar with linux. Come and hack - help and hints are welcome. Please contact Konrad Eisele [eiselekd@web.de] .
