Program Stored program concept iii. Instruction decoder
(b) Assume the following scenario:
In parallel with your OUSL studies, you wish to start a part time job in the IT field. Your interest is to the BPO industry, because your best friend is also working in a BPO company where jobs are available. According to your qualifications, you have the opportunity to join the same company. To start the job, your minimum requirement is a PC with reliable internet connection and a dot-matrix printer. You already own an Intel i5 processor and you wish to purchase the other hardware parts from the local market to assemble a PC to suit your requirement.
Explain the BPO job you plan to start. And prepare a budget for your requirement in PC hardware (H/W) and software (S/W) using the following table formats.

Q2. (a) Scenario:
Consider that you are working as a Programmer cum Systems analyst for an established computer training institute where hundreds of students are doing a one-year computer diploma programme. Students are having four continuous assessment activities during the year; two written tests and two practical tests. All four activities are evaluated separately and given percentage marks; t1, t2, p1,p2 respectively. Students are then grouped into three categories (of eligibility) based on their performance, and conduct the final examinations. You are assigned to build a computer program to analyse the activity marks and hence prepare the annual eligibility report. Eligibility criterion is given in the Table #1 below.
Criteria1: Average of best three marks (CA); CA>=40 |
Criteria2: Average of marks of two practical tests (PA); PA>=40 |
Status of Eligibility |
|
Yes |
Yes |
Eligible for the final examination |
|
Yes |
No |
P1>=50 |
Repeat the practical test2 only |
|
No |
P1<50 |
Repeat both practical tests |
No |
Yes/ No |
Repeat the full course next year |
Table #1: Eligibility Criterion
Assuming that the students’ index numbers and activity marks are available as a data file, construct an algorithm to demonstrate the logic of your program and show it in a flowchart using standard symbols.
Your program should output a record for each individual student in the following format.
Index number Status of eligibility CA mark (if applicable)
In your algorithm, it is compulsory to use the following pre-processor for one instance.
Reads the student’s index number and four activity marks from the data file (one student at a time) and stores in variables ind, t1, t2, p1, p2 respectively.
Hint: Assume the number of students be n and construct a loop statement.
(35 marks)
Consider the accumulator ISA of the Student Experimental Processor (SEP). According to the first digit of your registration number, select one of the following tasks with regrad to the algorithm in above (a). Write an assembly code for the selected
Task#1: To check whether CA>=40 and hence call one of the sub routines “check_criteria_2”
or “output_result” accordingly.
Task#2: To check whether PA>=40 and hence call one of the sub routines “check_p1” or
“output_result” accordingly.
