#104 – David Patterson: Computer Architecture and Data Storage

Über diese Folge

<p>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 &#8220;Computer Architecture: A Quantitative Approach&#8221; is how I first learned about and was humbled by the inner workings of machines at the lowest level.</p> <p>Support this podcast by supporting these sponsors:<br /> &#8211; Jordan Harbinger Show: <a href="https://jordanharbinger.com/lex/">https://jordanharbinger.com/lex/</a><br /> &#8211; Cash App – use code &#8220;LexPodcast&#8221; and download:<br /> &#8211; Cash App (App Store): <a href="https://apple.co/2sPrUHe">https://apple.co/2sPrUHe</a><br /> &#8211; Cash App (Google Play): <a href="https://bit.ly/2MlvP5w">https://bit.ly/2MlvP5w</a><span style="font-size: 1rem;"><br /> </span></p> <p><span style="font-weight: 400;">This conversation is part of the Artificial Intelligence podcast.</span>&#160;If you would like to get more information about this podcast go to <a href="https://lexfridman.com/ai">https://lexfridman.com/ai</a> or connect with @lexfridman on <a href="https://twitter.com/lexfridman">Twitter</a>, <a href="https://www.linkedin.com/in/lexfridman/">LinkedIn</a>, <a href="https://www.facebook.com/lexfridman">Facebook</a>, <a href="https://medium.com/@lexfridman">Medium</a>, or <a href="https://www.youtube.com/lexfridman">YouTube</a> where you can watch the video versions of these conversations.
