Haley 22W CST8216 Lab Assignment 4 - Lab Week Twelve Instructions The Problem Details for this assignment are on the pages following this one. Lab Week 12 – Assignment 4 – Problem Details Congratulations! The CST8216 Book Publishing Company have contracted you to write a software application that automates the current manual process used to validate International Standard Book Numbers (ISBNs). These are unique IBSNs used by "thousands and thousands" of Book Merchants to validate the authenticity of purchased books. The uniqueness of these IBSNs that they are either 13 or 10 Digits in length; however, we have been contracted to validate only those ISBNs that are 10 Digits in length, noting that the length does not include any hyphens “-“ in the ISBN. For example, the Joyce Farrell text used in CST8116 has an ISBN-10 of “ XXXXXXXXXX”, which we treat as a String. For IBSN validation, we analyze the “digits” form of the ISBN, which in this case would be XXXXXXXXXX. In the case of the Almy text used for this portion of CST8216, it has an ISBN-10 of “ XXXXXXXXXX”, which we treated as a String. For IBSN validation, we analyze the “digits” form of the ISBN, which in the case of the Almy text would be XXXXXXXXXX. The Current Manual Process of ISBN-10 Validation Some of the sources of information used for this assignment were based loosely upon, and noting that these sources use a “10 to 1” Method of Validation, but we will use a “1 to 10” Method. Once the Book Publishing Company has received a shipment of textbooks, a manual check of the IBSN is conducted using a “pencil and paper” method to perform the calculations required to validate the authenticity of the ISBN. Here are the steps: Extract the Digits “Extracted Numbers” from the “ISBN to Validate”. For each Digit (D), multiply it by the Multiplier (M) to obtain (DxM). Then, Sum the Products (SOPs) of all the (DxM) values and divide the SOPs by 11 ($0B). If the Remainder = $00 (0), then the ISBN is Valid; otherwise, the ISBN is Not Valid. Joyce Farrell Text example – valid ISBN: Remainder is zero (0). Almy Text example – valid ISBN: Remainder is zero (0). If, for example, one of the numbers in the ISBN was incorrect, then the validation would produce the following example results: Non-Authorized Version of Joyce Farrell Text example – Invalid ISBN: Remainder is not zero (0).Confirmation of Valid ISBN <== Calculated Valid Results1 to 10 Method <== Change these values to get Valid/Invalid ResultsDigit (D XXXXXXXXXX5 Base 10: Sum of Products (SOPs) 176Multiplier (M XXXXXXXXXX10 Base 16: SOPs $B0Base 10: Product (DxM XXXXXXXXXX63 50 Base 10: SOPS/11 16.0Base 16: Product (DxM) $01 $06 $09 $1C $05 $00 $0E $00 $3F $32 Base 16: SOPs/$0B $10Remainder $00Result Valid ISBNISBN to Validate Extracted NumbersXXXXXXXXXX‐337‐10207‐5Confirmation of Valid ISBN1 to 10 MethodDigit (D XXXXXXXXXX1 Base 10: Sum of Products (SOPs) 198Multiplier (M XXXXXXXXXX10 Base 16: SOPs $C6Base 1: Product (DxM XXXXXXXXXX XXXXXXXXXXBase 10: SOPS/11 18.0Base 16: Product (DxM) $01 $08 $12 $0C $23 $12 $38 $28 $00 $0A Base 16: SOPs/$0B $12Remainder $00Result Valid ISBNISBN to Validate Extracted NumbersXXXXXXXXXX1 to 10 MethodDigit (D XXXXXXXXXX5 Base 10: Sum of Products (SOPs) 184Multiplier (M XXXXXXXXXX10 Base 16: SOPs $B8Base 10: Product (DxM XXXXXXXXXX63 50 Base 10: SOPS/11 16.7Base 16: Product (DxM) $01 $06 $09 $1C $05 $00 $0E $08 $3F $32 Base 16: SOPs/$0B $10Remainder $08Result Invalid ISBNXXXXXXXXXX‐337‐10217‐5CST8216 Processor Architecture Lab Exercises Last Revision Winter 2022 Page 3 of 4 © 2022 D. Haley 22W CST8216 Lab Assignment 4 - Lab Week Twelve Instructions The Future Automated Process of ISBN Validation In the business of Software Engineering many manual processes are automated to improve efficiency, risk management and customer satisfaction. In a fully implemented system, we could scan ISBNs using a device such as the one depicted to the right. However, before adding such a device to our system, we would first have to prove that the functionality of the software is correct. As such, we will simulate the actual reading of the ISBNs using an external data file that contains exactly six ISBNs, which we will read into our assembly language program. Note that the illustrated data file contains the ISBNs from a previous lab and is not the file you will use for your submission. Rather, each lab section will have its own data file for ISBN Validation. As we iterate through the values, we will keep track of the Number of Valid ISBNs and the Number of Invalid ISBNs. An example result, using the ISBN.txt file from a previous Assignment (illustrated to the right) is illustrated below. Development Requirements and Constraints – The Test Plan The first thing you should do is to create a test plan of your program run BEFORE ANY CODE IS WRITTEN. It must contain the calculations that prove the validity of your results using the provided ISBN-10 validation algorithm. Your test plan must be based upon the file of ISBNs for your lab section. Students having trouble with this assignment will be asked to provide their test plan prior to receiving any assistance. Here are some sample results of the validation of the ISBNs from a previous assignment – your assignment submission would use the lab section specific data file and you must validate all six ISBNs and summarize the results as shown below. Note that you have been provided with a 22W Assignment 4 - ISBN Validation - Blank Sheet.xlxs file to complete and hand in with your submission.SUMMARY OF TEST CASE CALCULATIONS (EXPECTED RESULTS) File Name Used:  ISBN.txt  (Use the name of your Lab Section’s file here) List the ISBNs in their String below fcc "0‐684‐84438‐5" fcc "9971‐5‐0210‐0" fcc "93‐80954‐21‐4" fcc "0‐584‐84328‐5" fcc "950‐425‐059‐0" fcc "960‐425‐059‐0" Expected Results from calculated values above: Number of Valid ISBNs:       2 Number of InValid ISBNs:  4 CST8216 Processor Architecture Lab Exercises Last Revision Winter 2022 Page 4 of 4 © 2022 D. Haley 22W CST8216 Lab Assignment 4 - Lab Week Twelve Instructions Development Requirements and Constraints – Coding You must use the supplied starter code for 22W_IBSN_Validation_Driver.asm as your starting point. As you will see, some of the code has been predefined for your mandatory use and annotated “Do NOT change” within that file. There is also an algorithm provided to assist you in coding your solution. Pay particular attention to the labels Number_Of_Valid_ISBNs and Number_Of_InValid_ISBNs and how they are used; otherwise, the supplied code that outputs the results to the HEX displays will not correctly function. Starter code is also supplied for the two subroutines that you must write – Sum_Products.asm and Validate_ISBN.asm, using the ISBN 1 to 10 Method for validation as outlined in this document and by following the instructions contained in the starter code files. In addition, you should review the Subroutines – Rule Set for CST8216 – 29 March 2022 Update.pdf document to ensure that you are conforming to best practices for coding subroutines. It is included in this assignment package Development Requirements and Constraints – Program Output Using the ISBN.txt file from an earlier lab, the test plan provide us with the following Expected Results: Number of Valid ISBNs:     2 Number of InValid ISBNs:  4 A screen shot of the program output on the HEX Displays is illustrated.  Your solution to your provided ISBNs should also display a certain Number of Valid ISBNs as well as a certain Number of InValid ISBNs.    Note that if the program is run more than once in the Simulator – e.g. File  Reset, then clicking on Go, the same valid results must be correctly calculated by your solution and correctly displayed on the HEX Displays. Approach to Development There are at least a couple of methods one can use in Software Development:  the “Big Bang” approach where all of the code is written at once and then “fingers are crossed” hoping that the code works first time; or  the “Incremental” approach where you “code a bit, test a bit.” That is, you start off with the starter code in the Driver program, then add functionality to it as you go along. o In this assignment, you may wish one group member to code Sum_Products.asm and write a small driver program to send it one array to test the subroutine’s functionality against the test plan.  o In parallel, you could have another group member code Validate_ISBN.asm and write another small driver program to send in a SOP value to test the subroutine’s functionality against the test plan.  o Once you have that functionality working you can incorporate it into the Driver program then start looking at the iteration portion of the Driver where it must loop through all of the ISBNs, updating the valid and invalid results as appropriate.
