Summary

CS 315: Processor Construction Overview

  • Greg introduced his background and enthusiasm for teaching computer architecture, highlighting past experience building a processor.
  • The course emphasizes understanding how computers work from the ground up, leading to building a simple processor by the end of the semester.
  • He discussed rapid advances in AI and coding assistance, noting a recent example where a language model helped migrate a website between static site generators.
  • The first lab is due next week; students were encouraged to share perspectives on AI and coding assistance during introductions.

AI’s Role and Ethical Considerations

  • Participants discussed AI’s benefits and risks, including probabilistic outputs, data sources, and bias.
  • Greg stressed responsible use: AI as a tool, not a replacement for human expertise.
  • Open questions included AI’s impact on professional roles, creativity, and data ownership.

Balancing AI in Education

  • Greg described balancing AI tool use (e.g., ChatGPT’s Study Mode) with the need to preserve critical thinking.
  • He shared that Study Mode can be effective for learning languages like Rust and noted features that remember user context.
  • He emphasized student responsibility for learning and outlined assessment approaches designed to reward understanding, not shortcutting with AI.

AI Evolution and Societal Impact

  • The group discussed AI’s rapid evolution and integration into workflows.
  • Multiple viewpoints were shared:
  • Optimism about productivity and new capabilities.
  • Caution about ethics, responsible use, and long-term implications.
  • Examples included AI for data organization and analogies comparing AI to powerful tools that require careful handling.
  • The conversation highlighted the responsibility of future technologists to shape AI’s impact on society.

AI’s Impact on Education and Access

  • Perspectives included:
  • Creative uses (e.g., building mini websites with AI).
  • Concerns about ethical issues and reduced critical thinking, especially among younger learners.
  • Inequities in access to AI tools between schools in different socioeconomic contexts.
  • Greg emphasized the enduring importance of human empathy and interaction, citing nursing as a role unlikely to be replaced by AI.
  • Professional experiences shared by participants reflected cautious optimism.

AI and Programming: A New Era

  • Greg underscored that understanding programming fundamentals is key to effectively using AI tools.
  • He described a potential shift toward “software designers” who focus more on theory and system design, with AI handling more implementation details.
  • Debugging and problem-solving remain essential, with AI increasingly helpful in those areas.
  • Participants shared experiences and concerns about privacy and data usage in AI-enabled coding.

AI Tools and Economic Impact

  • Greg noted that AI lowers barriers for non-coders to create complex applications.
  • He acknowledged concerns about job displacement, while also pointing to scenarios where AI’s 24/7 availability could make it more expensive than human labor.
  • He plans to reassess course capacity within 2–3 weeks and may add students.

Teaching and Integration Insights

  • Greg reflected on prior teaching feedback, highlighting the need for practical, real-world application of AI concepts.
  • He emphasized foundational knowledge and integrating AI into software development processes.
  • He compared this course to a complex, serialized narrative (more “Game of Thrones” than “The Love Boat”), underscoring cumulative learning.

C, Binary Representation, and Architecture

  • The C portion of the course is a vehicle for understanding data representation (especially binary), not for producing professional C developers.
  • After a brief C review, the class transitions to assembly language with a focus on the RISC-V architecture.
  • Greg discussed Apple’s move to its ARM-based Apple silicon and noted that companies may consider RISC-V in the future due to its open nature and potential cost savings.

Assembly Language and Computer Architecture

  • The course traces the path from high-level languages (e.g., Java, Python) down to assembly and machine code.
  • Assembly is presented as a human-readable form of machine code—simpler in structure but capable of complex problem solving.
  • Greg explained cache memory’s role in bridging processor–memory speed gaps.
  • Digital design fundamentals will be covered intensively over ~3 weeks to enable students to build a basic processor.

Advantages of C and Rust Programming

  • C remains foundational in operating systems and embedded systems.
  • Rust offers memory safety without garbage collection trade-offs, making it valuable for systems programming.
  • Students will practice terminal workflows and debugging, especially for assembly.
  • SSH and remote development are emphasized, including work on Beagle machines used in course projects.

AI Tools and Course Structure

  • Greg supports using AI study tools and will provide prompts to guide labs and projects.
  • Course structure:
  • Weekly labs or projects.
  • Attendance: 10% of the grade.
  • Exams: 50% of the grade; notes are allowed, and practice problems will be provided to reduce anxiety.
  • Absences: no excused absences except with medical documentation; consistent attendance is encouraged.
  • The upcoming lab will focus on development environment setup. The syllabus, website, and first lab assignment will be distributed this week.
