Computer Organization & Architecture (CY-504 (C)) - Important Questions

  1. Unit 17 Marks High Priority Asked: 2023, 2024

    Describe the general register organization in CPU architecture. Explain the role of registers like Memory Register, Instruction Register, and Program Counter.

    Core topic; high frequency in past papers (heatmap shows 6 occurrences).

  2. Unit 17 Marks Medium Priority Asked: 2024

    How does the CPU handle stack operations? Explain with an example.

    Single-occurrence explicit question in recent paper; important for register/stack operations understanding.

  3. Unit 17 Marks Medium Priority Asked: 2023, 2024

    With the help of a diagram, explain the basic structure of a computer system, highlighting the components of the CPU, memory and I/O subsystem.

    Combined entry (similar questions appeared in 2023 and 2024). Consolidates questions asking for the basic structure and functional units of a computer with diagrammatic explanation.

  4. Unit 13 Marks Medium Priority Asked: 2024

    Architecture of a multicore processor

    Short-question style seen in recent paper; tests awareness of modern processor organization.

  5. Unit 17 Marks Medium Priority Asked: 2023, 2024

    Explain with neat flow chart for addition and subtraction of floating point Numbers.

    Core arithmetic topic; appeared multiple times in past papers (floating point operations and normalization).

  6. Unit 17 Marks Medium Priority Asked: 2023, 2024

    Explain the concept of Memory Hierarchy in computer architecture. Why is cache memory considered crucial in improving system performance?

    Fundamental architecture topic frequently examined; addresses performance and memory design principles.

  7. Unit 17 Marks Medium Priority Asked: 2023, 2024

    Differentiate between a hardwired control unit and a micro-programmed control unit with suitable diagrams.

    Classic comparison question; tests understanding of control unit designs and micro-architectural trade-offs.

  8. Unit 17 Marks Medium Priority Asked: 2023, 2024

    Define Interrupts and explain their types. How are interrupts handled in a microprocessor (case study: 8086)?

    Interrupts are core to processor control-flow and I/O handling; often asked with microprocessor case-study.

  9. Unit 17 Marks Medium Priority Asked: 2024

    What is Instruction Set Architecture (ISA)? Explain the various types of addressing modes with examples.

    ISA and addressing modes are foundational for assembly programming and instruction-format questions.
