This is the cheatsheet that the author used for the final examination of the course COMP2120 Computer Organisation. Please note that this cheatsheet may not cover all the topics in the course, but only those that the author found useful for the examination. To suit your needs, you may modify the source code of the cheatsheet and compile it yourself.

Warning

You are responsible for checking the examination regulations in your year of study. This cheatsheet may not comply with the latest examination regulations. The author is not responsible for any consequences should you violate the examination regulations.

Instructions for Printing

The PDF provided takes up the whole A4 page. Therefore, if you print the PDF at 100% scale, some of the contents at the edges will be cut off. Please use the option "Fit to Page" in your system's print dialog to ensure that the whole cheatsheet is printed correctly.

Adding Figures to Your Printed Cheatsheet

The examination may contain questions that are easier to solve if you have access to certain figures (including but not limited to the figures in the COMP2120-Notes and those included in the course materials). However, the figures are too large to be automatically typeset by LaTeX. Therefore, you may consider drawing them on the printed cheatsheet.

Suggested figures to include:

1. Floating-point number arithmetic operations flowcharts.
2. The flowchart of paging operations (of virtual memory).
3. Diagrams about Direct Memory Access (DMA) (please refer to the course slides) (This was tested in the 2025 May examination.).
