About this previous year paper
This document is the B.Tech SEM–III Theory Examination 2018–19 question paper for COMPUTER ORGANIZATION AND ARCHITECTURE (Sub Code: RCS302) under Dr. A.P.J. Abdul Kalam Technical University (AKTU).
The uploaded file contains two pages, clearly divided into SECTION A, SECTION B, and SECTION C.
The exam carries 70 marks, and the duration is 3 hours.
The paper evaluates fundamental and advanced topics in computer architecture, including instruction sets, addressing modes, memory hierarchy, pipelining, Booth’s algorithm, microprogramming, interrupts, and control unit design.
SECTION A — Short Questions (10 × 2 = 20 Marks)
(Page 1 — partially visible but follows standard RCS302 pattern)
Section A contains ten 2-mark questions, usually covering:
Basic architecture of computer systems Instruction formats
Addressing modes Register types
CPU organization fundamentals Cache basics
ALU operations RISC vs CISC
Data transfer techniques Control signals
(Exact text not fully visible due to cropping, but Section A exists as per exam format.)
SECTION B — Descriptive Questions (4 × 5 = 20 Marks)
(Page 1 — standard long-theory section)
Students attempt any four of the 5-mark questions.
Topics typically include:
Hardwired vs Microprogrammed control Memory organization
Cache mapping Interrupt structure
Instruction cycle description DMA operation
Register transfer language examples Arithmetic pipeline concepts
(Section B questions are part of the printed page but not fully captured in the image. However, the section structure is confirmed from the exam header.)
SECTION C — Detailed / Applied Questions (7 × 3 = 21 Marks)
(Page 2 — fully visible)
This section contains three main questions (Q3, Q4, Q5).
Each question has two alternatives (a or b), and the student must attempt one from each pair.
Q3 — Instruction Pipeline / DMA & Interrupts
(a) Short notes on:
Instruction Pipeline
DMA-based Data Transfer
(b) Difference between vectored and non-vectored interrupts, with examples.
(All text visible in Page 2 image.)
Q4 — Booth’s Algorithm / Amdahl’s Law & Pipelining
(a) Draw the flow chart of Booth’s Algorithm and show multiplication using Booth’s method for:
(−7)×(+3)(-7) \times (+3)(−7)×(+3)
(b) Short notes on:
Amdahl’s Law
Pipelining
(Clearly shown in Page 2 image.)
Q5 — Microprogram Sequencer / Control Unit
(a) Explain microprogram sequencer with block diagram and working.
(b) Explain control unit design and functions.
(Visible on Page 2.)
