This course should develop students’ sense of “what really happens” when
software runs — and convey 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 role of the operating system (but not how the operating system is implemented).
For (computer science) students wanting to specialize at higher levels
of abstraction, this could in the extreme be the only course they take
that considers the “C level” and below. However, most will take a subset
of Systems Programming, Hardware Design and Implementation, Operating Systems,
Compilers, etc. For students interested in hardware, embedded systems,
computer engineering, computer architecture, etc., this course is the introductory
course after which other courses will delve both deeper (into specific
topics) and lower (into hardware implementation, circuit design, etc.).
The course has three principal themes:
- Representation: how different data types (from simple integers to arrays
of data structures) are represented in memory, how instructions are encoded,
and how memory addresses (pointers) are generated and used to create complex
- Translation: how high-level languages are translated into the basic instructions
embodied in process hardware with a particular focus on C and Java.
- Control flow: how computers organize the order of their computations,
keep track of where they are in large programs, and provide the illusion
of multiple processes executing in parallel.
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
- 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;
- be more effective programmers (more efficient at finding bugs, improved
intuition about system performance).
