Project Description

1. What is the address of element 36 (assuming you start counting at 1) of a 45-element array that starts at memory location 40 if the elements are:

a. characters b. integers c. 7-byte structs d. 10 character strings

2. A 12 by 11, 2-dimensional array, has its first row and column numbered 0,0. The base address is 1000, and each element is a word. What is the byte address of element [8,10] assuming row-major form? What is the byte address of element [8,10] assuming column-major form?

3. Using an array to implement a stack, write a SPIM program that reads a string and prints out its value if executed in postfix notation. Make sure to report if the input is not in correct postfic form. For example: 897*6-+, should return 65, (i.e. 8+ (63-6)), but 7**78+ is not in correct postfix form and should return a message rather than a value. The stack should make it easy to check whether or not the input is correct. You may assume that all numbers are single integers between 0 and 9, and that operations are either *, ??" or +. We will review the algorithm for this in class.

4. Write a SPIM program that takes a 6 by 8 two dimensional array of integers, stored in row-major form, and copies it to a 6 by 8 array stored in column-major form. Print the array in 6 rows separated by linefeeds, with each row containing 8 integers separated by spaces. Then print each array in the order it is linearly stored.
