I think this is a good idea. I'll start with today:

- Generated binary for DES kernel and patched the instructions with NOPs
    - Tried to get code working there but couldn't because I didn't know
where data is supposed to be loaded from / how the kernel is supposed to be
initialized
- I experimented with the kernel initialization process:
    - Tried to remove various lines from the beginning to see if I get error
    - Unfortunately I got an error almost all the time
    - It is not clear when an error occured. When it happens you usually
get the results of the last execution (maybe due to a lack of clean-up
after the previous exec)
    - I didn't find any reference in any documents about the kernel's
initialization and what should be loaded from where - maybe I should look
further

For tomorrow:
- I will change the "binary_gen.c" so that it passes the same type and
number of kernel arguments as blowfish takes. This way we will be able to
copy the kernel initialization from the ISA file of blowfish and hopefully
get LDS instructions working.

Regards,
Daniel
