ISAs, registers, and instruction formats: Lab, Review, and Transfer

This is 55AA-006B, week 1, session 2. It focuses on "ISAs, registers, and instruction formats" and turns the weekly plan into discussable, practicable, and reviewable class artifacts.

Learning Objectives

  • Explain where "ISAs, registers, and instruction formats" fits in this course and what core problem it addresses.
  • Analyze a case or system related to "ISAs, registers, and instruction formats" using today's method.
  • Connect the session task to the course outcome: Read and write small assembly programs.
  • Complete the questions, notes, and synthesis required by workshop, exercise, and review.

Prerequisites

  • Computer organization fundamentals.
  • Have read the weekly task: Write and single-step a small RISC-V program.
  • Be able to record assumptions, evidence, risks, and questions to validate in class.

Preparation

  • Open the 55AA-006B course repository, readings, and this week's task brief.
  • Write two true/false claims or open questions about "ISAs, registers, and instruction formats" before class.
  • Be ready to show questions, lab notes, or project fragments from the previous meeting.

Class Flow

0-8
Review previous conclusions

Quickly review the concept framework and unresolved questions for "ISAs, registers, and instruction formats".

Question

When judging "ISAs, registers, and instruction formats", what fact should be confirmed first?

Expected answer: First confirm the object, boundary, attacker or user capability, observable evidence, and evaluation criteria.

Follow-up: If that fact is not directly observable, what minimal experiment would you design?

Script

Opening

Today's session focuses on "ISAs, registers, and instruction formats". We will not treat it as an isolated topic. We place it in the course workflow: define the object and boundary, gather evidence, and turn the result into engineering action.

Review

Return to the previous discussion. State one important conclusion in a sentence, then state one remaining uncertainty. We will carry those uncertainties into today's analysis.

Demo / Exercise

Question

Where is the weekly task "Write and single-step a small RISC-V program." most likely to fail?

Expected answer: Common failures include unclear goals, insufficient evidence, unreproducible environment, and conclusions without process.

Follow-up: What checklist item would reveal this failure early?

Script

Guided question

Here is the first judgment question: if we know only the conclusion but not the environment, inputs, or evidence, can that conclusion guide engineering decisions? Answer yes or no first, then name your assumptions.

Script

Explanation

For "ISAs, registers, and instruction formats", the key is not memorizing definitions but following an analysis order: define the object, list boundaries, state who can do what, find observable evidence, and turn the conclusion into a task or test.

Peer review

Exchange results and check reproducibility, explanation quality, and missed risks.

review
Question

What makes a lab result reviewable by someone else?

Expected answer: It needs environment, commands, inputs, outputs, failure conditions, screenshots or logs, and explanations for anomalous results.

Follow-up: How would you write this requirement into homework or project acceptance criteria?

Script

Practice transition

Now apply that order to the weekly task: Write and single-step a small RISC-V program. Do not write only the final answer; preserve how you ruled out alternatives.
