David Patterson is a Turing award winner and professor of
computer science at Berkeley. He is known for pioneering
contributions to RISC processor architecture used by 99% of new
chips today and for co-creating RAID storage. The impact that
these two lines of research and development have had on our world
is immeasurable. He is also one of the great educators of
computer science in the world. His book with John Hennessy
“Computer Architecture: A Quantitative Approach” is how I first
learned about and was humbled by the inner workings of machines
at the lowest level.
