Summary

This is the first lecture of the Digital Design and Computer Architecture course at ETH Zurich, Spring 2026, taught by Prof. Onur Mutlu. The lecture introduces the course structure, teaching team, and the fundamental concepts of computer architecture. Prof. Mutlu emphasizes the importance of designing better computers, considering metrics like performance, energy, robustness, and sustainability. He discusses the transformation hierarchy from problems to electrons, and introduces the transistor as the basic building block of digital logic, comparing it to a wall switch. The lecture sets the stage for the course, which will cover topics from transistors to microprocessors, including memory-centric computing and processing-in-memory. The instructor also highlights the need for intelligent architectures and the impact of computing on sustainability. The lecture is aimed at undergraduate students and assumes no prior knowledge, but it also touches on advanced research topics like RowHammer and genome analysis acceleration.

Critical Evaluation

Value of the Information & Strength of the Argument

The lecture provides a high-level overview of computer architecture, emphasizing the importance of designing better systems. The argumentation is strong, as Prof. Mutlu connects fundamental concepts to real-world challenges like energy consumption and sustainability. He uses analogies (e.g., transistor as a wall switch) to make complex ideas accessible. The value lies in setting a solid foundation for the course, motivating students to think about design trade-offs and the broader impact of computing. The argumentation is persuasive, encouraging students to adopt a growth mindset and consider multiple metrics beyond just performance.

Scientific Rigor, Source Quality, Title Accuracy

The lecture is scientifically rigorous, with Prof. Mutlu citing his own research and providing links to papers on processing-in-memory, RowHammer, and genome analysis.
