This lecture gives an introduction to processor design.
It is mostly interesting for people new to processor design and does not cover high performance pipelined structures.
Small knowledge on VHDL programming would be great but is not essential. A very small processor core will described here.
Demo:
Create a backdoor in the VHDL Code of a processor core.
Exploit this backdoor to get a root shell in the linux operating system.
Processors are getting more and more complex. Only a small part of the hacker comunity really understands what is going on in them.
This lecture introducess processor design for the normal C/Assembler programmer. During the lecture a very small self wirtten processor core is introduced.
Mentioned subjects:
- why build your own processor core
- Instruction Set Architecture
- Fenite State Machines
- Compiler
- RegisterFile
- Arithmetical and Logical Unit
- Fetch Unit
- Decode Unit
- Main Memory
- Processors and Security
Demo:
Create a backdoor in the VHDL Code of a processor core.
Exploit this backdoor to get a root shell in the linux operating system.

I am a computer scientist working on reconfigurable hardware and processors. I am visiting hacker camps since 2007 and i am a member of the famous geraffel villiage since Chaos Communication Camp 2011.
I already did a presentation on reconfigurable processors at CCC2011 and about processor desgin at OHM2013.
