Comp 3350: Computer Organization & Assembly Language

HW # 5:  Theme: Data Definitions, Addressing Modes, Arrays

1. [Memory Map] Fill in the following memory diagram with the data provided below. Please assume that the data segment begins at 0x0040400A.

1. [Addressing Modes] Copy the following code into your assembly development environment and single-step through it.  For each single step execution, submit the screenshot.  For those instructions referencing memory, do the linear address computation (typewritten/handwritten). 

1. [Indirect addressing] Write a program that adds the corresponding elements of Array1 and Array2 and stores the results in Array3; e.g. for the 8th element, Array3 [7] ß Array1 [7] + Array2 [7].  Include commands to display the elements of all the arrays.  Submit screenshot of the displays of the elements of all the arrays.  You can use WriteInt or WriteHex to display the elements of the arrays.

1. [Loops] Write a program to compute the sum of first n odd integers.  Sum = 1 + 3 + 5…+(2n-1)  Your program must:

1. Prompt user for integer n, 
2. Read the value of n from user input
3. Calculate Sum, and; 
4. Print Sum on screen.
