This assignment will have you implement branching and loops by developing an assembly language program to find the largest and smallest values contained in an array.
This assignment will have you implement branching and loops by developing an assembly language
In the data segment of the program, define an array of 10 words. Arbitrarily assign values for each element of the array to include both positive and negative numbers. After the array, define two additional data values for the smallest and largest values, initialized to zero. Therefore, there will be three data definitions in the data segment.
In the text segment, code the sequence of instructions to iterate through the array, saving the smallest and largest values into two designated registers. One example
Initialize small = large = arr[0]
Repeat from i = 1 to n
if(arr[i] > large)
large = arr[i]
if(arr[i] < small)
small = arr[i]
As was demonstrated in the example programs in the lecture materials, make sure you perform all necessary and appropriate initializations prior to entering the loop.
The following high-level code represents the above logic:
large = a[0];
small = a[0];
for (i=1; i<n; ++i)
{
if (a[i] > large)
large = a[i];
if (a[i] < small)
small = a[i];
}
You will need to associate registers for the values represented by variables. Make sure you include the required register usage list in your program.
At the end of your text segment, just before the exit code, store the values for smallest and largest into the memory locations allocated for each in the data segment.
After successfully executing the program, create a memory dump and label the contents as was required in previous assignments. You will have three labels: the array, the smallest value, and the largest value.
Include comments throughout your program as appropriate.
