IMPORTANT NOTES ABOUT THE CLASS
1. Due Dates: Lab reports (or assignments) are due as indicated
on handout and should be turned in during class. Late reports
can be turned in to the CIS secretary in 114 ELB. Such reports
must be initialed by the secretary and the date and time when
received must be written on the report by the secretary. If this
is not done, instructor will use the date when picked up by the
instructor. Since instructor does not pick up mail everyday,
this date may be several days after the report is turned in.
Penalty for late reports is -5% per weekday (-50% max).
2. Computer Access: Dial-up access to the campus computing
facilities is available through Merit/Michnet. Direct-wired
access and several workstations and PC's are available at various
labs on campus.
3. E-Mail: Students may use electronic mail to communicate with
the instructor.
4. Comments in Programs: It is good programming practice to put
lots of comments in programming assignments. It is required to
include your name, course number, and instructor's name as
comments in all programming assignments.
5. Laboratories: Lab experiments will be performed using a
MC68332 development board. You will work in pairs in the
laboratory. The instructor and a student assistant will be
available to help with the labs. Both members of a pair are
expected to participate in the lab.
6. Cheating Policy: The work submitted must be that of the team
or individual student. The minimum penalty for cheating will be
a zero for the plagiarized work.
7. Attendance Policy: You are responsible for all activities that
transpire in all classes. This includes exams, assignments,
announcements, and so on. If you miss a class, you should obtain
notes from a classmate.
8. Exams are based on class notes/discussions. The texts provide
background reading. Make-up exams are only given in exceptional
cases. Such cases must be properly documented and the instructor
must be notified in advance.

NAME: __________________________________________
This assignment replaces lab 1. It consists of 3 questions from the
Lipovski text and 13 questions from the Harman text. Give only the
final answer in all cases. If you wish, you may attach your
detailed solution as additional pages. Answers that do not
terminate should be given correct to five decimal places unless
otherwise specified. The additional information/instructions in
italic for each question is important. In case of any conflict, the
additional instructions on this sheet take precedence over the
instructions in the texts.
LIPOVSKI, PAGE 115, #4 A 74HC133 chip being unavailable, use a
drawing to show how to implement such a chip's function using the
least number of 74HC04s and 74HC20s (see Figure 3.10). Note that
the 74HC04 consists of six inverters in one package (one chip), and
the 74HC20 consists of two 4-input NAND gates in one package.

LIPOVSKI, PAGE 116, #5A A decoder chip being unavailable, use a
drawing to show how to implement such a chip's function using the
least number of SSI gates as indicated (see Figure 3.10).
a. Implement a 74HC138 using 74HC04s and 74HC20s
Note that the 74HC138 is a 3-to-8 decoder. Do not include the
enable inputs, E1, E2, and E3, in your implementation. Just assume
the chip is always enabled.

LIPOVSKI, PAGE 117, #10 Draw the block diagram of a completely
specified decoder using arbitrarily large AND gates with appropriate
bubble inputs and outputs, like Figure 3.9, for Table 3.3's memory
map. Include R/W and E control signals in each decoder as needed.
Note that this question only asks for a block diagram.

HARMAN, PAGE 40, #2.2.3 The MC 68332 CPU can address byte (8
bits), word (16 bits), or longword (32 bits) operands. For each
operand length, draw a diagram showing the logical organization of
an eight-byte buffer in memory starting at location 1000. Label the
bit positions and addresses. A buffer is an area in memory that
holds data temporarily during I/O transfers. Just draw the
diagrams. Do not describe the differences.

disadvantages of including a real-time operating system in a

cost. Give one advantage and one disadvantage. Give brief answers.

sign-magnitude, one's complement, and two's complement forms for an
m-bit representation if:
(a) m = 8
(b) m = 16
(c) m = 32

statement, given in hexadecimal, into the assembler-language
(symbolic) equivalent:

block of memory for storage and then initialize it to the successive
values 1 through 20 upon execution. Attach the handwritten or typed
source listing. You may complete one or both of the following
optional tasks for extra credit of 5 or 10 points:
Extra Credit of 5 points: Assemble your program using the assembler
supplied in CD-ROM with the Lipovski text. Attach the assembly
listing to show that your program was assembled successfully.
Extra Credit of 5 points: Execute your program using the emulator
supplied in CD-ROM with the Lipovski text. Attach a computer-
printed printout or other proof to show that your program was
executed successfully.
