The value of this assessment is 30 marks.

**Answer the following questions**

**Q.1** a. Determine the value of base x if (211)_{x} = (6A)_{16} [5 marks]

b. Convert the followings: [3+3=6 marks]

0xBAD into a decimal number

588_{10} into a 3-base number

c. Given a (very) tiny computer that has a word size of 6 bits, what are the smallest negative numbers and the largest positive numbers that this computer can represent in each of the following representations? [3 +3 = 6 marks]

One's complement

Two's complement

**Q.2** a. Consider the following logic diagram of a combinational circuit where A, B, and C are inputs and Q is the output. Three 2-input AND gates and two 2-input OR gates are used in the circuit. It is possible to reduce some of the logic gates without changing the functionality of the circuit. Such component reduction results in higher operating speed (less delay time from input signal transition to output signal transition), less power consumption, less cost, and greater reliability. Construct a logic diagram of a circuit which does have the same function output with only two logic gates (instead of five). Please show the steps. [8 marks]

b. Using basic Boolean algebra identities for Boolean variables A, B and C, prove that ABC+ ABC' + AB'C + A'BC = AB + AC + BC. Please show all steps and mention the identities used. [5 marks]

1. a. The Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and are characterized by the fact that every number after the first two is the sum of the two preceding ones: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 114, … etc.

By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two. We define Fib(0)=0, Fib(1)=1, Fib(2)=1, Fib(3)=2

Fib(4)=3, etc. The first 22 Fibonacci numbers given below:

Fib(0) | Fib(2) | Fib(2) | Fib(3) | Fib(4) | Fib(5) | Fib(6) | Fib(7) | Fib(8) | Fib(9) | Fib(10) |

0 | 1 | 1 | 2 | 3 | 5 | 8 | 13 | 21 | 34 | 55 |

Fib(11) | Fib(12) | Fib(13) | Fib(14) | Fib(15) | Fib(16) | Fib(17) | Fib(18) | Fib(19) | Fib(20) | Fib(21) |

89 | 144 | 233 | 377 | 610 | 987 | 1597 | 2584 | 4181 | 6765 | 10946 |

Write a MARIE program to calculate Fib (n), where the user inputs n. For example, if the user inputs 7, the program output the value 13; if the user inputs 15, the program outputs the value 610; if the user inputs 20, the program outputs the value 6765 etc. You need to write and run the program using MARIE simulator. Please include appropriate comments to make your code readable.[10 marks]

b. For some values of n, your program will not produce correct results. You can check this by gradually increasing the values of n and checking for the correct outputs. What is the maximum value of n for which your program produces a correct result? Why? Please comment on this [5 marks].

2. You are designing an instruction set for your computer. All the instructions are of same size (11 bits long). The size of an address field is 4 bits. You have already designed 5 2-address instructions and 45 1-address instructions. How many 0-address instructions still you can fit? Justify your answer. [7 marks]

3. Write codes to implement the expression: A= (B + C * ) on 3-, 2-, 1- and 0-address machines. In accordance with programming language practice, computing the expression should not change the values of its operands. [8 marks]

The online quiz will be on all topics of the subject. Each time you will have 20 multiple choice questions and you will receive 20 minutes to finish it. Attempting online quiz many times will help you to prepare for the final exam too, as you will have similar type of multiple choice questions in the exam

Students face off various problems in completing this assessment such as understanding the complex problems of making references, lack of writing skills etc. Students can take help and guidance from our technical experts and get better grades in their assessments
