教学大纲

This course should develop students’ sense of “what really happens” whensoftware runs — and convey that this question can be answered at severallevels of abstraction, including the hardware architecture level, the assemblylevel, the C programming level and the Java programming level. The corearound 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 beimplemented), lower levels (the general structure of a processor), andthe role of the operating system (but not how the operating system is implemented).For (computer science) students wanting to specialize at higher levelsof abstraction, this could in the extreme be the only course they takethat considers the “C level” and below. However, most will take a subsetof 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 introductorycourse after which other courses will delve both deeper (into specifictopics) 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 structures.
  • 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 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
  • Memory hierarchy
  • Implementation of high-level languages

华盛顿大学是位于华盛顿州西雅图市的一所公立研究型大学。华盛顿大学成立于 1861 年 11 月 4 日,原名领土大学,是西海岸历史最悠久的大学之一,在西雅图建市约十年后落户西雅图。

该大学的主校区位于该市的大学区,占地 703 英亩,在塔科马和博特尔也有校区。总的来说,华盛顿大学由 500 多座建筑和 2000 多万平方英尺的总面积组成,其中包括世界上最大的图书馆系统之一,拥有 26 个学术图书馆、艺术中心、博物馆、实验室、演讲厅和体育馆。

华盛顿大学是华盛顿州六所公立大学中的旗舰院校。它以医学、技术和科学研究而闻名。
