Write an ARM assembly program in Keil to check whether an Nx N matrix is a magic square. A magic square is an Nx N matrix in which the sums of all rows, column, and the two diagonals add up to N (N2 + 1)/2. All matrix entries are unique numbers from 1 to N². Register r1 will hold N. The matrix starts at location 0x20000010 (Base address) and ends at location (Base address +3 -N²). Note: Here it is assumed as all numbers are bytes, you need to consider the 4-byte size of integers,

**ARM Assembly Program for Magic Square Verification** This educational resource provides guidance on writing an ARM assembly program using Keil to verify whether an N × N matrix is a magic square. **Definition of a Magic Square:** A magic square is an N × N matrix where the sums of all rows, columns, and both diagonals equal N(N² + 1)/2. All entries are unique and range from 1 to N². - **Register Details:** - Register r1 holds the value of N. - The matrix is stored in memory starting at address 0x20000010 (Base address) and ends at (Base address + N²). - Each number is stored as a byte, so consider the 4-byte size for integers. **Example:** Below is an example of a magic square: ``` 16 3 2 13 5 10 11 8 9 6 7 12 4 15 14 1 ``` The numbers are stored consecutively in memory: - 16, 3, 2, 13 occupy the first four addresses. - 5, 10, 11, 8 occupy the next four addresses, and so on. **Program Output:** - If the matrix is a magic square, register r8 will be set (value of 1). - If not, it will be cleared to 0. This information helps understand the structure and logic necessary for evaluating magic squares using ARM assembly language.
