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 3 487654 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 ,…

Intro to software engineering: Q5- A company supplies a Tax Returns Automation process to its clients, visiting their sitesand inspecting their revenues for a given year, giving advice and completing the necessaryforms for Tax Returns purposes. Once the forms have been completed, they are saved aspaper copies; one is kept by the client, the other is filed locally within the company’s paper-based archives. The corresponding electronic copies are also saved in a word-processorformat and saved on a local computer.The company is seeking to develop a more fully automated process: the tax consultantvisiting the client's premises periodically would log-in to an on-line application (within thecompany website) and input the data to an on-line form. The data collected would be used tokeep the clients informed of the results of the consultant’s visits and the date of the next visit.Considering the above scenario:a) List and describe at least THREE possible risks that the company will be…
