Anna University Computer Architecture Question Paper __top__ <2025-2026>

To effectively use the , you must know which topics dominate the exam hall. Based on analysis of the last 5 years (2019-2024), here is the high-probability radar:

For Regulation 2021 (e.g., CS3351 - Digital Principles and Computer Organization), the paper typically follows this 100-mark distribution:

Before we look at the questions, let’s look at the structure. The total mark is (External: 75, Internal: 25).

Don’t skip Part C. Even if you write the pipeline stages correctly without the solution, you will get 5 out of 15.

As the semester exams approach, the search term spikes across search engines. Students scramble to find previous year papers, model questions, and solved answers to secure a high GPA. However, merely downloading a PDF is not enough. To truly excel, one must understand the pattern, the repeating concepts, and the art of presentation.

This section contains five questions, usually split into two parts (a) and (b) per question, corresponding to the five units. Students must answer one from each unit.

1 comprehensive or application-oriented question designed to test higher-level analytical skills, such as analyzing pipeline hazards or designing a memory system. High-Weightage Topics

15. A computer has a 5-stage pipeline. Assume there is a branch instruction. Explain how data and control hazards occur. Design a solution to minimize the performance loss due to these hazards.

| Section | Format | Marks | No. of Questions | | :--- | :--- | :--- | :--- | | | 2 Marks (Definition/Short Note) | 20 | 10 (2 from each unit) | | Part B | 13 Marks (Explain/Derive) | 65 | 5 (1 from each unit) | | Part C | 15 Marks (Design/Scenario/Problem) | 15 | 1 (From Units 1-3 or 4-5) |
