Please carefully read the following instructions before attempting assignment.

RULES FOR MARKING
It should be clear that your assignment would not get any credit if:
• The assignment is submitted after the due date.
• The submitted assignment does not open or file is corrupt.
• Strict action will be taken if submitted solution is copied from any other student or from the internet.

You should consult the recommended books to clarify your concepts as handouts are not sufficient.

You are supposed to submit your assignment in .doc or docx format.
Any other formats like scan images, PDF, zip, rar, ppt and bmp etc will not be accepted.

Objective:

Objective of this assignment is to increase the learning capabilities of the students about

• To understand the conversion of numbers in to binary by using arithmetic operations.
• To understand the basic concept of logical operations and how to use it to solve a problem.

NOTE

No assignment will be accepted after the due date via email in any case (whether it is the case of load shedding or internet malfunctioning etc.). Hence refrain from uploading assignment in the last hour of deadline. It is recommended to upload solution file at least two days before its closing date.

Question # 01 10 marks

In CPU all the arithmetic operations are performed in binary numbers (0 and 1). Suppose you have a small CPU which is designed to perform all arithmetic operations using addition only. You will explain how the following operations will be solved out by the CPU.
i) Multiplication of 6 and 2
ii) Addition of 7 and 3
iii) Subtraction of 5 and 4

Question # 02 10 marks

You have an image that can be represented in 8 bits. The image is given below:
(00110011)2
You are required to send this image to someone but not in original form. So, nobody can extract the features from the image.
So, we will perform following two operations on the image.

1. Masking
   You will apply an 8-bit (10101011)2 mask using AND logic operation.
2. Inversion
   You will invert the masked image using XOR logic operation.
