CPU 1001 Simulator
This is a tool aiming to explain to general public how a processor
works. The tool accompanied the article in a newspaper. The story is
published in Daily News column 1001 in October 2014. The article in
Thai language is divided into two parts for a weekly consumption (I also
wrote it in English, see the link below). I will update this page
from time to time to refresh my general idea how to write for public
service.
