In this assignment, you will program a simple calculator for the Raspbian OS using ARM assembly. Your program, at a minimum, will consist of the following procedure calls SUM: Adds registers R1 and R2, returning result in register RO DIFFERENCE: Subtracts register R2 from R1, returning result in register RO PRODUCT: Multiplies registers RI and R2, returning the result in register RO MIN: Compares registers RI and R2, returning the minimum of the two values in RO Your main function will contain a loop that continuously checks for keyboard input in the following pattern: Where can be any of the four characters+*,m. Once the 3 lines of input are acquired, the operands should be loaded into the proper registers and the procedure corresponding to should be called. The procedure should return the result in register RO, and the main function should print the value to the console and skip to a new line You may ignore overflows, underflows, and improperly formatted input. All input test cases will consist of positive numbers only. Below are some example use cases: 50 200 100 20 100 20 30 20 Where can be any of the four characters+*,m. Once the 3 lines of input are acquired, the operands should be loaded into the proper registers and the procedure corresponding to should be called.
