This course examines key computational abstraction levels below modern high-level languages; number representation, assembly language, introduction to C, memory management, the operating-system process model, high-level machine architecture including the memory hierarchy, and how high-level languages are implemented. We will develop students’ sense of “what really happens” when software runs — and that this question can be answered at several levels of abstraction, including the hardware architecture level, the assembly level, the C programming level and the Java programming level. The core around which the course is built is C, assembly, and low-level data representation, but this is connected to higher levels (roughly how basic Java could be implemented), lower levels (the general structure of a processor and the memory hierarchy), and the role of the operating system (but not how the operating system is implemented).
At the end of this course, students should:
- understand the multi-step process by which a high-level program becomes a stream of instructions executed by a processor;
- know what a pointer is and how to use it in manipulating complex data structures;
- be facile enough with assembly programming (X86) to write simple pieces of code and understand how it maps to high-level languages (and vice-versa);
- understand the basic organization and parameters of memory hierarchy and its importance for system performance;
- be able to explain the role of an operating system;
- know how Java fundamentally differs from C;
- grasp what parallelism is and why it is important at the system level; and
- be more effective programmers (more efficient at finding bugs, improved intuition about system performance).
Topics:
- Number representation
- Assembly language
- Basics of C
- Memory management
- Operating-system process model
- High-level machine architecture
