Question
Computer Science
Using memory-mapped I/O and polling, write a function print_string that prints a string on
the display, without using any system call. The address of the string is passed in register $a0
and the string must be null-terminated. Test this function by calling it from the main function.
Make sure to activate the “Keyboard and Display MMIO Simulator”.

- you will use a link library procedure call to effect stdout display. Write a program that displays the same string in four different colors, using a loop. Call the SetTextColor procedure from the text link library. Any colors may be chosen, but you may find it easiest to change the foreground color. Store values into the EAX and EBX registers. Compile and run your program to validate that your program sequence of statements exchanges the original register values. Define a string to be displayed in the data segment that includes YOUR name. Example: str1 byte "This line is displayed in color selected by Ann Napa",0arrow_forwardImplement the code block for the for statement. Implement any other code necessary tocomplete the program. The final assembly code for this program should look similar to thefollowing..text la $a0, prompt jal PromptInt move $s1, $v0 li $s0, 0 li $s2, 0 # Initialize the total start_loop: sle $t1, $s0, $s1 beqz $t1, end_loop # code block add $s2, $s2, $s0 addi $s0, $s0, 1 b start_loop end_loop: la $a0, output move $a1, $s2 jal PrintInt jal Exit.data prompt: .asciiz "enter the value to calculate the sum up to: "arrow_forwardDesign a simple program that asks the user to enter a store's sales for each day of the week. The amounts must be stored in an array using a loop - see below. Use another loop to calculate the total sales for the week and display the result. Also calculate the average of the daily sales and report that. Notes A loop structure with a single input instruction must be used to populate the array with the user's entries for the daily sales amounts After the user has entered the daily sales amounts, a separate loop must be used to accumulate the daily amounts into the total sales for the week Report out an average daily sales amount in addition to the total sales for the week.

- Coin Toss, v.2.0 Purpose. Learn how to use count-controlled loops. Requirements. Rewrite your coinTossl.cpp from exercise 6.5 as coinToss2.cpp. Modify the program to allow the user to specify (via keyboard data entry) the number of coin tosses to perform. When you run the program, and it should say the result of each coin toss (that is, "Heads" or "Tails"). Supplemental. Read about "randomizing" in www.rdb3.com/cpp/exercises/Gaming.supplemental.pdf. Algorithm. Call srand Prompt the user to enter how many coin tosses to perform Input and store the user's selection Create a counter and set it to zero Start the loop here If the counter equals the number of tosses to perform Break from the loop Get and store a randomly-generated number in the range 0 to 1 If the randomly-generated number equals 0 Output "heads" If the randomly-generated number equals 1 Output "tails" Add one to the counter Loop back from here Example. with user input in blue Enter the number of tosses to perform: 3 Heads…arrow_forwardMatlab Questionarrow_forwardMUST BE WRITTEN IN C++ Write a program so that user can use it to compute and display various statistics for a list of at least 3 values and up to 20 positive real values. The main objectives of this project are to work with menu, arrays, file input, and modules/functions. A menu is available and user can select one of the 4 options from the menu. The program will continue until option 4 is selected. For option 1, process a predefined array in the code with 3 values (73.3 83.4 58.0). User will be able to input an array from the keyboard with a sentinel loop with option 2. Use the following values (73.3 83.4 58.0 11.9 25.1 69.9 45.7 95.0 44.4)as one of your test cases (use-1.0 as a sentinel value). When option 3 is selected, input data from a text file. Use the given p2input.txt Download p2input.txt as a test case. The values in the file are shown below. 73.399.0 83.4 58.0 25.1 69.0 11.9 95.0 74.8 55.0 43.5 47.4 95.6 58.9 52.6 37.7 93.8 19.9 23.9 77.2 You can assume that the user will…arrow_forward
