Project Description This project will help you to familiarize yourself with MIPS assembly language and encoding of MIPS instructions to machine language. Write an assembly program threeTimes.asm that: 1. 2. 3. 4. Prompts the user to enter 3 integers Displays the 3 integers Prints the sum of these three multiplied by the number 3 Use the starter code file, threeTimes.asm, and make the necessary modifications for this project. Remember, to place YOUR name at the top of the code. An example dialog follows: This is Dianne Foreback presenting threeTimes. Please enter an integer: 5 Please enter an integer: -3 Please enter an integer: 12 The sum of your numbers multiplied by 3 is: 42 Aside: Notice 42 (5 + (-3) + 12) * 3 Project Description This project will help you to familiarize yourself with MIPS assembly language and encoding of MIPS instructions to machine language.
