EE350 - COMPUTER ARCHITECTURE
Time: 3hrs Max Marks: 100
Answer all Questions
PART – A (10 x 2 = 20 Marks)
1. What is MAR and MBR? What will be the content of MAR and MBR for read and write operation?
2. Define stack. Following operations were performed on stack, which contains an integer item 10.
Push 20, Push 30, Pop, Push 40, Pop, Pop.
What will be the top element of stack after above all operations were completed?
3. Explain with an example, the 2's compliment subtraction.
4. Define Bit-slice processing. What is a bit slice?
5. RISC processors typically have instructions of equal size. What is advantage of such choice?
6. Define micro instruction and micro program.
7. What is the need for memory hierarchy?
