Nios/peak

Write a function that returns the peak-to-peak amplitude of a signal stored in an array of 32-bit signed words. This is the difference between the maximum and minimum samples.

The function has two parameters. The first parameter is the length of the array (at least 1). The second parameter is a pointer to the beginning of the array.

unsigned int peak(unsigned int length, int *array);

Sample Input

[1, 2, 3]

Sample Output

r2=2

# A test case to test your function with
Array: .word 1, 2, 3

.global _start
_start:
    movia r4, 3 
    movia r5, Array
    call peak
    br _start        # End of testing code

# Return the difference between max and min array elements
peak:
