Coursework Assignment
4CCS1CS1 Computer Systems
Introduction
This is a summative coursework for CS1. It counts for 15% of your final module grade. The assignment
provides you with the opportunity to apply your knowledge and skills that you’ve gained from previous
labs to some new tasks. You will need to write an assembly program, which will then be submitted to
KEATS as a single .s file.
You have just under two weeks to complete the assignment. The deadline for submission is Friday
24th November 18:00. The suggested time to spend on the coursework is 8–10 hours.
In the labs following submission of the coursework, you will review each others programs and provide
feedback to each other. This peer review is a mandatory part of the assessment, and non-participation
in the review activity will result in your coursework mark being capped at 40%.
1 Display your k-number (15 marks)
Using the circuit from Lab 5, you should write a program to display the digits of your King’s K-number
on the LEDs.
Have your program write out each digit of your K-number separately, writing the left-most numerical
digit first. For example, if your K-number is K1070542, then your program will first write out a 1,
followed by a 0, then a 7, then a 0, then a 5, then a 4, and finally a 2. Each number should be
displayed for 1 second.
2 Display your initials (20 marks)
You should now modify your program so that it also displays a binary encoding of your initials after it
has finished displaying your K-number.
There are many ways to encode alphanumeric characters in binary, the most common is ASCII. However,
we will use our own encoding of alphanumeric characters. We will assume an ‘A’ is the decimal value 1,
a ‘B’ is 2, a ‘C’ is 3 and so on. In this encoding, ‘Z’ would be 26. Again, you can use the look-up table
later in this document to find the equivalent binary values that you will display, and accompanying
hexadecimal values.
You should also display a full stop character ‘.’, which we will assume is encoded as the value 27,
between your initials.
For example, Ada Lovelace’s program would first display her K-number. The program would then
display the value 1 (00001, representing ‘a’), then the value 27 (11011, representing ‘.’), and then the
value 12 (01100, representing ’l’).

Display Morse Code (10 marks)
You will now extend your program to communicate Morse code on the LEDs.
What is Morse code? Morse code is a method of transmitting text information as a series of on-off
tones, lights, or clicks that can be directly understood by a skilled listener or observer without special
equipment. (https://en.wikipedia.org/wiki/Morse_code).
Below is the International Morse Code Roman alphabet.
Your base program will blink a 3 letter sequence in Morse code on the LEDs. You three letter sequence
is the first three letters of your first name.
• For example, Charles Babbage’s code would be CHA.
• If your first name is less than three characters, you should use the first 3 characters of your first
name concatenated with your surname. For example, Jo Rowling’s code would be JOR.

So that we can perceive the Morse code, we will use a unit length of 200 milliseconds (ms). This
means the duration of a dot is 200 ms, and a dash is 600 ms.
For example, if your sequence was ABC, then your program would run as follows:
1. Turn ON the LED for 200 ms for the first dot of the letter A
2. Turn OFF the LED for 200 ms for the inter-part space of the letter A
3. Turn ON the LED for 600 ms for the first dash of the letter A
4. Turn OFF the LED for 600 ms for the inter-letter space between the letters A and B
5. Turn ON the LED for 600 ms for the first dash of the letter B
6. ... and so forth
7. Until the last dot of letter C
8. Turn OFF the LED for 1400 ms for the inter-word space.
9. Loop back to the beginning of the Morse code sequence
3 Odd, Even, modulo 5 (15 marks)
Extend your program as follows.
• The Morse code sequence should loop 50 times (1–50).
• On odd iterations (1, 3, 5, ..., 49) your three characters should be displayed in their normal order.
– e.g. ABC
• On even iterations (2, 4, 6, ..., 50) your three characters should be displayed in reverse order.
– e.g. CBA
Using comments, you should explain how you have implemented the check of whether the iteration is
even or odd.
Once you have this behaviour working, you should again extend your program as follows.
• On iterations that are divisible by 5 (5, 10, 15, ..., 50) your program should display a ‘5’ after
what would normally be displayed on that iteration.
– e.g. ABC5 or CBA5
4 Ping-pong (20 marks)
Once the Morse code sequence has terminated, your LEDs should display a repeating pattern.
You should use the LEDs to display a ping-pong like pattern, where only a single LED is on at a time,
and it appears to move back and forth across the LEDS.
• 1000 → 0100 → 0010 → 0001 → 0010 → 0100 → 1000 → ...
It is left up to you to determine a suitable time to display each pattern for.

Submission instructions
• You should submit a single .s file named assignment.s via KEATS.
• DO NOT put your program in a .zip, .7z, or any other archive, DO NOT submit your program
as a .doc, .pdf, or any other format other than .s.
• This coursework uses ‘Model 4’ for use of generative AI. That is, you can use generative AI to
help you with the coursework. However:
– I have tried to use it myself for completing the coursework, it was not very helpful. Do not
expect generative AI to spit out complete assembly programs for you.
– You should make it clear in the comments where and how you have used generative AI.
– It is your responsibility to ensure any code produced by generative AI is ‘fair use’.
Mark scheme
• There are 100 marks available in total.
• Marks for correctness are awarded according to the number of marks for that task (80 marks).
• Marks for readability and style are also awarded (20 marks).
– Is your code structured and neat?
– Is your code commented well?
– Have you made use good use of the constructs we’ve covered in previous labs, e.g. functions,
conditionals, and loops.
