Hello, Phillipp.
Thanks for your feedback.

Indeed, we can not speak about compression algorithms correctness without
assurance that the trace can be recovered. That is why I suppose to
implement compression (verilog RTL) + decompression (a C program) and debug
them in a stand-alone setup early in timeline. Apparently, this is not
clear from timeline.
I corrected timeline and added decompression details.

2) You state in your proposal:

That is correct. My estimation is based on the following: my current job
has a flexible schedule. So it is convenient for me to shift the working
day (it is obviously from 12 a.m to 8 p.m.). So I have about +2 or +3 free
hours in the morning on weekdays and Saturday (+ 8 hours). It gives about
+20 hours and Sunday for a day off. Besides this a 4 week vacation can be
allocated to focus on GSoC full-time.
I added a brief summary to proposal.
