This course presents a bottom-up introduction to computer
architecture, beginning with digital gates and number representation;
building up through the Von Neumann model, Instruction Set
Architecture (ISA) and assembly language; and ending with C programs
interacting with assembly programs. Most of the concepts in this
course will be reinforced through programming assignments in C.
In CS 270 students write a number of C programs to learn concepts by
programming them and to build confidence in the C programming
language, which is an important language used frequently in industry
and systems research. There will be at least one deliverable a week.
