Computer Organization & Architecture

1.Design a single precision and a double precision floating point number for the provided decimal numbers (2 X 4)
(A) 0.0001
(B) 2345. 234

2. provided the subsequent memory values and one-address machine instruction with an accumulator, what values do the subsequent instructions load into the accumulator?
Word 20 contains 40
Word 30 contains 50
Word 40 contains 60
Word 50 contains 70
presume Accumulator begins always with the value 80
i) LOAD IMMEDIATE 20
ii) LOAD DIRECT 20
iii) LOAD INDIRECT 20
iv) LOAD IMMEDIATE 30
v) LOAD DIRECT 30
vi) LOAD INDIRECT 30
vii) ADD INDIRECT 70
viii) ADD DIRECT 40 (8 X 1)

3. explain the different addressing available for general computer giving an example for every. (8)

4. Write an 8086 assembly language program to calculate the sum of 2 arrays and to store the outcome in 3rd array, presume a word data. (8)

5. Perform P X Q using Booth’s algorithm and verify the identical using bit-pairing technique where P = 23 and Q = -15. (2 X 4)
