MIPS Assembly Language Program in SPIM To Perform Some Math Operations Assignment Solution

Instructions

Objective

Write a MIPS assignment in SPIM to perform some math operations.

Requirements and Specifications

Write a SPIM program to calculate 2 * ( 111 + 333) - 12345.

Use R8, R9, and R10 to store the values 10, 20, and 15 respectively. Store the result in R12. Run the program and submit the screenshot (showing program code and register values).

Write a SPIM program to "prompt the user to enter" a radius of a circle (integer only), and to display the diameter (use add - do not use MUL). The radius and the diameter can be stored in the registers.

Write a SPIM program to prompt the user to enter two numbers x and y (integers only), and to display their sum z, z = x + y. All x, y, and z can be stored in the registers. Register Mapping: x: $t0 , y: $t1, z: $t2 (Use RAM to store those value).
