Question

Need to write a MIPS assembly program that finds the minimum and maximum and sum of a stored array. It also finds the locations of the minimum and maximum.

The interaction between the main program and the function is solely through the stack. The function stores $ra immediately after being called and restores $ra before returning to main.

The main program reserves a static C like array (index starts from 0) of 10 elements and initializes it. The maximum should be in locations 4 and 5 (same number) and the minimum in location 7. Locations 0, 1, 8, and 9 should contain the same value. Furthermore, the main program stores the base address of the array in $t0 and the array size in $s0 and has to use these registers after calling the function (you do not have to code the register usage).

The function receives the starting address of an array of 32-bit integers and the number of elements in the array from the main program, finds the maximum integer, the minimum integer within the array, and the average value of the elements in the array and returns the maximum, minimum, average, and the locations of the minimum and maximum values in the array to the main program. Further assume that the function uses $t0 as a pointer to array elements. Additionally, the function stores the index used to “navigate”through the array in $s0. Hence, both $t0 and $s0 are changed by the function.

After calling the function, and receiving the results, the main program prints these results to the screen and stops.
