This course provides a bottom-up overview of a modern computer system. It first unveils the inner workings of a general-purpose microprocessor building up from simple logic circuits. It then demystifies assembly code—the machine language spoken by the processor—and the mapping of assembly programs to higher levels of programming abstraction. With an understanding of how the microprocessor executes programs, the course then shows how a high-level programming language such as C makes those abstractions concrete, and exposes the static and dynamic structures of programs. Students learn the organisation principles of a simple microprocessor, how it can be realised in a simulator, and programmed in assembly. Students also build a non-trivial real-world application in the C programming language.

More specifically, the course covers:

·     Introduction to digital systems and logic, including Boolean algebra, logic gates, and combinational logic

·     Instruction set architecture (ISA) design principles with a specific focus on the ARM ISA

·     Microarchitecture of a simple ARM processor

·     Memory and I/O systems

·     C programming language, translation of C programs to ARM assembly, and C program runtime organization including call stack and heap

·     Basic I/O utilities in C and memory mapped I/O

·     Relationship between programming language abstractions and assembly code

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Explain the underlying structure and behavior of a microprocessor and the design principles of modern instruction set architectures
2. Illustrate the memory and storage hierarchy of a modern computer system
3. Discuss how computer systems perform simple input/output operations and interact with their environment and map assembly programs to/from a high-level programming language
4. Design a processor for a given instruction set architecture
5. Describe the runtime layout of C programs, including the address space, call stack, heap, and function pointers
6. Write C programs that manipulate the heap using pointers and explicit memory management
7. Compose non-trivial real-world applications in C using data structures allocated in the heap

Policies

ANU has educational policies, procedures and guidelines , which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Integrity Rule before the commencement of their course. Other key policies and guidelines include:

• Academic Integrity Policy and Procedure
• Student Assessment (Coursework) Policy and Procedure
• Special Assessment Consideration Guideline and General Information 
• Student Surveys and Evaluations
• Deferred Examinations
• Student Complaint Resolution Policy and Procedure
• Code of practice for teaching and learning

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the Academic Skills website. In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.

Participation

The assessments in this course demand hands-on training. Without attending tutorials and submitting and testing the laboratory exercises every week, the students will find it extremely hard to finish the assignments. Therefore, we expect high participation in the tutorials. Each lecture will offer an in-class quiz which will prepare students for the final exam. Therefore, attending the lectures and participating in the discussions and solving the quiz questions is extremely important.

Examination(s)

There will be a final exam worth 40%. The exam will cover the course content covered in lectures in the first eleven weeks.

Assessment Task 1

CPU Design

The first assignment in this course requires designing and building a working processor in a logic simulator. The students will be provided hands-on training with the use of the required tools. The students will be provided with a specification of the instruction set architecture.

Assessment Task 2

Programming Assignment

The second assignment in this course requires students to solve a real-world problem in the ARM assembly language.

Assessment Task 3

Final Exam

There is only one examination in this course. The final exam will be held during the exam period.

Academic Integrity

Academic integrity is a core part of the ANU culture as a community of scholars. The University’s students are an integral part of that community. The academic integrity principle commits all students to engage in academic work in ways that are consistent with, and actively support, academic integrity, and to uphold this commitment by behaving honestly, responsibly and ethically, and with respect and fairness, in scholarly practice.

The University expects all staff and students to be familiar with the academic integrity principle, the Academic Integrity Rule 2021, the Policy: Student Academic Integrity and Procedure: Student Academic Integrity, and to uphold high standards of academic integrity to ensure the quality and value of our qualifications.

The Academic Integrity Rule 2021 is a legal document that the University uses to promote academic integrity, and manage breaches of the academic integrity principle. The Policy and Procedure support the Rule by outlining overarching principles, responsibilities and processes. The Academic Integrity Rule 2021 commences on 1 December 2021 and applies to courses commencing on or after that date, as well as to research conduct occurring on or after that date. Prior to this, the Academic Misconduct Rule 2015 applies.

 

The University commits to assisting all students to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. All coursework students must complete the online Academic Integrity Module (Epigeum), and Higher Degree Research (HDR) students are required to complete research integrity training. The Academic Integrity website provides information about services available to assist students with their assignments, examinations and other learning activities, as well as understanding and upholding academic integrity.

Online Submission

The assignment submission will be through the teaching Gitlab. You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records.

Hardcopy Submission

The two assignment submissions in this course will be soft copy submissions. We are aiming for in person (paper) exams. We will adjust the policy as per circumstances.

Late Submission

Individual assessment tasks may or may not allow for late submission. Policy regarding late submission is detailed below:

• Late submission not permitted. If submission of assessment tasks without an extension after the due date is not permitted, a mark of 0 will be awarded.

Referencing Requirements

The Academic Skills website has information to assist you with your writing and assessments. The website includes information about Academic Integrity including referencing requirements for different disciplines. There is also information on Plagiarism and different ways to use source material.

Extensions and Penalties

Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure. Extensions may be granted for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date. If you have documented and appropriate medical evidence that demonstrates you were not able to request an extension on or before the due date, you may be able to request it after the due date.
