Homework Number: 1A Date of Submission: XX

Homework 1A

An alien species have landed on earth that have four hands with 9 fingers on each hand (36 fingers in total). They follow a base-36 number system. We will define variable 'X' and variable 'Y' in their number system. The first 3 letters of your first name is variable X, last 3 letters of your last name is variable Y, first letter of your last name is variable Z (For example for Mahbubur Rahman, X=MAH, Y=MAN, Z=R, X,Y,Z are in base-36)

Problem 1: Convert X and Y to decimal, binary, hexadecimal and octal number

Problem 2: In binary and decimal, compute X+Y, X-Y. Compute 2's complement of Y in binary and recompute X-Y

Problem 3: Represent the floating point number X.Y in IEEE single precision floating point number

Problem 4: Convert X to grey code and ASCII

Problem 5: Install Altera Quartus. Show the value of Z in Binary and hexadecimal. Attach a printed copy of the waveform with your file

Homework 1B

Problem 1: Convert Z from problem 1 into binary and take the first 8 bits from the MSB. Assume the function f(A,B,C) is defined as these first 8 bits denoted by 'G'. Write the truth table of the function, write the function in terms of Sum of Products and Product of Sum form, and draw a K-map of the function and reduce it to minimum form.

Problem 2: Write a verilog code that generates fibonacci sequence of a number. (

Fibonacci number, Fn = F(n-1) + F_(n-2); F_0 = 1; F_1 = 1

Input: clock Output: 16 bit fibonacci number

each time clock changes state from 0 to 1, the fibonacci number output is changed, showing from F_0, F_1, F_2 etc.

Case 1: F_0 = 1; F_1 = 1; (Regular fibonacci number) Case 2: F_0 = G; and F_1 = 1;

Show (print) output for both cases for 16 different clock changes
