Final answer:
The task involves writing ARM assembly code to count odd numbers in an array and copy them to another array. It requires programming loops, conditions, and subroutines. Proper stack frame management is also crucial.
Step-by-step explanation:
The subject in question involves using ARM assembly language to perform a specific task on an array of integers (words). The task requires writing an assembly program that will traverse through a 40-word array to count how many of those words are odd numbers, store that count in a register, and then place the odd numbers into a new array.
To accomplish this, you need to use loops to iterate over the array elements, conditional branches to test for odd numbers, a counter to keep track of the number of odds, and an index for inserting elements into the new array. Moreover, the use of subroutines can modularize the code, making it cleaner and more reusable.
An example of a subroutine might be one that checks if a number is odd and then increments a counter if it is. Another subroutine could be used to insert an odd number into the new array. Remember to set up the stack frame correctly if you're using local variables within your subroutines.
