Jun 7, 2024

Explanation

The student has provided an exam question about ARM assembly language programming. The task is to write two ARM assembly programs: one to find the maximum absolute value in an array, and another to shift bits in a register.

Step-by-step Instruction

▪

Choose to use ARM assembly language syntax and instructions

▪

Define concrete use cases and testing cases for the functions: for the first function, it should return the maximum absolute value; for the second function, it should shift the bits as described

Question 1: Find the Maximum Absolute Value

assembly

Main Function for Testing

assembly

Time Complexity

O(n), where n is the number of elements in the array

Space Complexity

O(1), as we are using a fixed amount of extra space

Question 2: Shift Bits in Register R9

assembly

Main Function for Testing

assembly

Time Complexity

O(1), as the operations are constant time

Space Complexity

O(1), as we are using a fixed amount of extra space
