Which should you choose?

Choose Code if you want

Readers with no technical background.

The strongest starting point here, building from simple circuits up to a processor with no prerequisites. It explains ideas broadly and offers little hands-on practice, so it ranks below the textbooks for working understanding.

Choose Digital Design and Computer Architecture if you want

Hardware design students learning HDL and logic.

A clear intermediate path from logic gates and HDL to a microprocessor design, with a hardware focus. It covers software and systems topics less than the computer systems textbook, so it ranks below that book for general readers.
