Write ARM Assembly program to do: - ISBN Checksum Validator Use Keil uvision software to write and simulate an ARM assembly program that checks the validity of a given ISBN by verifying the checksum Helping Information to solve program : 1. An ISBN consists of nine digits plus a validation digit. 2. The digits are numbered from right to left as d1, d2 ... d10, with d1 being the validation digit. 3. You can define the ISBN number in a 10-byte array in the memory. Each digit is stored in a byte. 4. To check whether the ISBN is valid or not, the following calculations are performed: Result = (10 x d10 + 9 x d9 + ... + ix di + ... + 2 x d2) % 11 Calculate d1 = 11 - Result If the calculated d1 equal to the d1 in the input ISBN then it is valid If d1 = 10, it is written 'X' For example, given the following ISBN: ISBN = 5123487654 ISBN= 5 1 2 3487654 d10 d9 d8 d7 d6 d5 d4 d3 d2 d1 Result = x 10 + x 9 + x 8 + X 7 + x 6 + x 5 + x 4 + x 3 + x 2 mod 11 = 216 mod 11 =7 d1 = 11 - Result = 11 - 7 =4 then the input ISBN is valid, since the calculated d1 is equal to the d1 in the input ISBN. Some ISBN examples: The ISBN 5123487654 is valid The ISBN 5123487658 is not valid The ISBN 7465159237 is valid
