### Solution

__Title of the task:__ Computers, data and programming

__Subject code__: ITC544

__Objective of assignment__

This part of assignment requires students to apply practical and numerical skills to resolve radicals and conversion of different numerals hour into fractions.

__Overview of assignment__

This assignment comprises of different questions for the conversion of several bits into fractions. Students needs to convert hexadecimal values to decimal values and to attempt different questions present in the assignment for the provision of binary conversion. There is a need to include octal representation and Marie program. Output of each and every numerical is required to include.

__University: __CSU university

__Deliverables of the task__

Following are the main tasks which are required to be covered by the students approximately 1200 words.

Question 1: first of all, exponent is calculated and the fraction value is converted into the point value to get the right expression. After that hexadecimal value is converted to decimal value and decimal value to octal representation.

Question 2: it includes MARIE program which comprises of assessment code and description.

Question 3: it describes high order interleaving and low order interleaving with proper description. Proper description of asked question and screenshot is required in this question.

__Sample output__

__Suggested modifications in assignment__

Each and every numerical should be represented clearly in the assignment. Each and every question should be solved separately by the students. It is suggested to include the screenshot for showing the output of different questions in order to achieve higher grades. The proper clarity of different numerical is also required in the assignment add student should use tables represent particular numerical.

__Comments by experts__

The review of work of different student is not considered as easy task. there is a need to have proper knowledge on each and every aspect of numerical. Solving numerical is the most difficult part of assignment which requires proper technical knowledge. With the support students get experts for solving numerical.

Answer the following Questions
Question 1.
a) A Computer uses IEEE -754 single precision format to represent floating points. What value (in
decimal) the computer represents if the floating point is represented using the following binary
digits. Show al l the steps used in finding the answer.

0 01111110 10100000000000000000000
b) Convert the following numbers. (Please show all steps; no marks will be awarded if no steps are
shown) [1.5 x 4 = 6 marks]
i) 0xAD9 into 3 -base representation
ii) 4518 into 2 -base (binary) representation
iii) 123.35 into octal representation (up to 3 octal points)
iv) 14.358 into decimal representation
Question 2.
Write a MARIE program that accepts an integer from the user, and if it is a prime number the
program will output 1, otherwise, the program will output 0.
Examples:
If the user input is 17, the output would be 1
If the user input is 2, the output would be 1
If the user input is 15, the output would be 0
If the user input is -2, the output would be 0
You should write and run the program using MARIE simulator. Add enough comments to understand
your code.
You do not have to include the .mas file i n the submission. Instead, the code should be presented as
a word -processed section in the assignment, not as an image.
Insert images to show you have tested the code with several possibilities.
[10 marks]
Question 3.
a) Explain with an example of what is meant by high -order interleaving and low -order interleaving in
memory organisation.
[3 marks]
b) Suppose we have a memory consisting of 32 4Kx8 -bit chips.
Show the address structure and module organisation when
i. high -order interleaving is used
ii. low -order interleaving is used.

Criteria
HD (85% -100%) DI (75% -84%)
CR (65% -74%)
PS (50% -64%)
FL (0% -49%)
Comprehension of data representation and application of computer math calculations
All calculations were correct. Appropriate mathematical symbols were used, and all steps/workings
were shown.
Almost al l Calculations were correct except a minor error.
Most of the calculations are correct. However, few steps were omitted. The methods used to solve
the problem were correct, but there were one or two miscalculations.
At least half of the calculations were correct. Some incorrect answers were the result of errors at
some stage of the calculation, which propagated with the next steps. Some of the steps showed the
basic understanding the numbering system.
No attempt or most of the calculations were incorrect. Failed to show the steps of calculation. Either
the answers were incorrect or the steps were wrong.
Simulating and investigating of internal operations of CPU and it's instruction execution
(programming skills)
The code meets the specification. Code is well documented with comments. The program produces
correct outputs in every input situations.
Code meets specification and is well documented with comments. Minor errors in explanations.
Code meets specification. Most of the time produces correct results , however does not produce
correct results for special inputs. Little documentation and comments.
Code meets specification but has errors in operation. Little commenting. Basic idea is expressed by
the codes and explanations.
Code does not meet the specifi cation.
Comprehension of internal elements of computer organisation
Answers are corrects. All steps are correctly shown.
All codes are accurately written.
All answers are correct with a minor error. All codes are correct except a minor error.
Few minor er rors in calculating the address spaces. The steps show the clear understanding of the
address space calculation.
All codes written correctly however the order were not maintained correctly. The final result is not correct, however the calculations show th e basic understanding of the
instruction set architecture.
More than half of the codes are correct.
No attempt or incorrect calculations showing no or minimum understanding of the topic.
