Assembly Multiplication Table

Objective

introduce you to the MIPS ISA using MARS. You will create a block diagram by draw.io and pseudocode to help you design the structure of your program. Then you will write a program with a nested loop to print a multiplication table to the screen.

Functionality

This program will prompt the user twice for integers. The first integer entered must be in the range [1, 82] (smallest valid input: 1, largest valid input: 82). For the second user input, the smallest valid integer is one greater than the previous user input and the largest valid input is 83.

If the user enters an invalid integer, an error message will be printed and the user will be prompted again.

After user input is gathered, a multiplication table will be printed in the format shown below. The multiplication table will have 12 rows (for multipliers 1 through 12), not including the header row that lists the multipliers indicated by user input.

Specification

Example Outputs

User inputs 4 and 16

Enter a positive integer in the range [1, 82]: -9

Invalid entry!

Enter a positive integer in the range [1, 82]: 4

Enter a larger positive integer in the range [5, 83]: 4

Invalid entry!

Enter a larger positive integer in the range [5, 83]: 16
