                         Course Information Sheet

                               Spring 1998

This course is intended to provide students with a basic architecture
of computer systems including fundamental concepts such as data
representation, CPU registers, memory management, addressing modes,
and system organization.  These concepts are integrated through the
use of assembly language.

Course outline:

* Computer Architecture and Organization
	-Data Representation
	-Boolean Algebra
	-Basic System Organization
	register structure, memory structure, stack, input/output,
	system bus, system timing, instruction fetch and execution
	-Addressing Modes
* Assembly Language
	-Assembly program development
	-Computer instruction sets
	data transfer instructions, arithmetic instructions, logical
	and bit instructions, string instructions, program flow
	control instructions, and miscellaneous instructions
	-MS-DOS and PC-BIOS interrupt service routines
	-Subroutines

Evaluation:

There will be a number of programming assignments. Each assignment has
a due date and time. Assignments must be received before the due date
and time.  Late programs will be accepted but with a penalty of 5
points (out of a total of 100) per day. There will be 3 in-class
quizzes, a midterm and a final exam.  Grades will be computed from a
score weight by:

Programs		25%
In-class quizzes	15%
Midterm exam		25%
Final exam		35%

Grade Conversion: The following scale will be used but the instructor
reserves the right to lower the numerical score required for a
particular letter grade if that seems appropriate, but the same
conversion will be applied to all persons in the class. Under no
circumstances will the numerical score required for a particular letter
grade be raised.

90-100A+
85-<90A
80-<85A-
75-<80B+
70-<75B
65-<70B-
60-<65C+
55-<60C
50-<55D
<50F
