Question 1

Design a memory interface system for the 8088 microprocessor in the address range

AFFFFh to AE000h, using 2k RAM chips. Draw a clear diagram and show all steps. When you finish your design, determine what address range will fall within the scope of the last page.

Question2

Write an assembly program that read two numbers from the user. Each number consists of two decimal digits (0-9). The program should then read an operation from the user, which can be one of the following: *, -, +. The program should then perform the chosen operation on the two input numbers and print the result in binary.

Question 3

Write an assembly program that reads a single digit number, n, and then calculates the value of the nth element in the Fibonacci series. Each element in the Fibonacci series is equal to the sum of the two previous numbers. The first two elements in the series are both 1.

Question 4

Write an assembly program that reads a string and a character from a user and then counts the number of times the character appears in the string. Store this number in DL.
