Due February 3 in class
PLEASE HAND IN PARTS A AND B SEPARATELY!!!!
For “written” questions, please type your answers, use your
very best English, and carefully
consider the material from the chapters. I am usually only
looking for a few sentences for each
question, not an essay that goes on for pages. So choose your
words carefully and thoughtfully.
PART A
[1] Does a computer need data registers (like D0–D7 in an
M68K)? Defend your answer!
[2] Textbook question 5.35. If your student number is even, do
parts (a), (c), (e) and (g). Otherwise do
parts (b), (d), (f) and (h). Note that (b) should read “[[[4]]]”, (c)
should read “[[[0]]]” and
(h) should start with “[0]”.
[3] Explain why the following assembly language and RTL
constructs are incorrect.
a. MOVE D3,#4
b. MOVE [D3],D2
c. MOVE (D3),D2
d. [D3] A0 + 3

2. e. [D3] #3
f. 3 [D3]
[4] Create a simple M68K program called ADDER. Your
program should add together the numbers:
6, 4, 12, 16, 17, and 50. The program should leave the answer in
register D0 when it terminates.
The program is to be assembled with the M68K cross-assembler
and then run on the M68K simu-
lator. You can either install the cross-assembler and simulator
given with the textbook (windows)
or you can use the Linux one available on the course web site.
Doing a trace (to hand in) with the
windows version is much more painful than the Linux version,
so make your choice carefully (and
you have to figure out the windows one without my help).
To use the Linux assembler (“68kasm”) and simulator (“bsvc”),
follow the instructions in my
mail message of January 26, if you have not already done so.
IMPORTANT NOTE: if you are using the Linux simulator, the
instructions for creating a program
are slightly different than those in the book. You should have
the following at the start of each
program:
ORG $0
DC.L $8000 This is the stack pointer value after a "reset"
DC.L START This is the first instruction to execute

3. You can then follow that with something like
1
ORG $1000
START MOVE ...
You should still have a STOP instruction and END assembler
directive, as described in the book,
but also use a BREAK instruction right before your STOP
instruction.
Create your program (ADDER.s) in your (for example)
comp2213/bsvc-master directory using
your favourite text editor and assemble it with the command
68kasm -l ADDER.s. If you had no
assembly errors you should now have a file called ADDER.h68
(which is your executable program)
and ADDER.lis (your program listing). Then start up the
simulator by typing bsvc. Select
File/Open Setup, drill down to samples/m68000, select
serial.setup and click Open; a
new window should pop up on your screen. Now choose
File/Load Program, come back up to
your bsvc-master directory, and open your ADDER.h68
program. Now click the GUI’s Reset
button and then the Run button. (Alternatively, instead of Run
click Single Step and watch the
result of each instruction.)
After you get your program working, create something to hand
in by single-stepping through
your program until it finishes, and then use the Trace menu to

4. insert the register values into the
trace window, and then save that window (again from the Trace
menu). Hand that file and your
program listing in. If you are using the windows software, do
whatever it takes to hand the
same information in. The tutors have looked at the Linux
software and should be able to help you
with it, but you are really on your own with the windows
software.
There are some sample programs in the samples/m68000
directory. To learn how to use bsvc,
you might find it instructive to run the MatrixMultiply.h68
program using the serial setup.
PART B
[5] What is wrong with each of the following M68K assembly
language operations?
a. MOVE Temp,#4
b. ADD.B #1,A3
c. CMP.L D0,#9
d. MOVE.B #500,D5
[6] Translate the following fragment of high-level language into
M68K assembly language. Then
create a complete M68K program containing your code, and use
a M68K simulator to test your
program.
IF T = 5
THEN X = 4

5. ELSE Y = 6
END_IF
Hand in the program listing and program trace as in Question 4.
2
[7] A sequence (string) of one-byte ASCII characters is stored
at memory location $600 onward. A
second sequence of equal length is stored at memory location
$700 onward. Each sequence ends
with the character $0 (i.e., the ASCII NUL character). Write a
M68K assembly language program
to determine whether or not these two strings are identical. If
they are identical, place the value
$00 in data register D0. If they are not, place the value $FF in
D0.
Use the M68K cross-assembler and simulator to test your
program (make up a couple of your own
strings, using the DC.B assembler directive). Hand in the
program listing and program trace as in
Question 4.
[8] Write a subroutine ADDABC that performs the operation C
= A + B. Variables A, B, and C are all
word (i.e., 16-bit) values. Test your program on the M68K
simulator by writing a main program
which sets up values in A and B and then calls your main
program.
Your calling code and subroutine should have the following

6. features:
� Parameters A and B should be passed on the stack to the
procedure by reference (i.e., by
address). Parameter C should be passed back to the calling
program on the stack by value.
� Before you call the subroutine, make room on the stack for
the returned parameter (i.e.,
parameter C). After calling the subroutine, read the parameter
off the stack into data register
D0 (i.e., D0 should end up containing the value of A + B).
� The subroutine ADDABC must not corrupt any registers.
Save all working registers on the
stack on entry to the subroutine and restore them before
returning from the subroutine.
� When you write your code, preset the stack pointer to a value
like $1500 (by using either
MOVEA.L #$1500,A7 or LEA $1500,A7). Doing this will make
it easier to follow the
movement of the stack while your program is running.
� Make certain that you are operating with the correct operand
sizes! Use .W for data values
and .L for addresses/pointers.
� Some of the important instructions you might need are
provided below. Make sure you
understand exactly what they do.
MOVEM.L RegList,-(A7) Push a group of registers on stack
MOVEM.L (A7)+,RegList Pop a group of registers off stack

7. LEA X(Ai),Aj Load Aj with the contents of Ai + X
MOVEA.L (Ai),Aj Load Aj with longword pointed at by Ai
Your program should be of the general form:
ORG $0
DC.L $8000 Initial value of stack pointer
DC.L START First instruction here
ORG $400
START LEA $1500,A7 Set up the stack pointer with an easy
value
... Pass the parameters
BSR ADDABC Call the subroutine
... Get the result, C, in D0
... Clean up the stack
STOP #$2700 Halt execution
3
*
ADDABC ...
...

8. RTS
*
ORG $1200 Put the test data here
A DC.W $1234 This is the first parameter
B DC.W $ABAB This is the second parameter
END START
This is not an easy or trivial problem. You will need to draw a
map of the stack at every stage and
take very great care not to confuse pointers (addresses) and
actual parameters.
Hand in a listing and trace of your program as descried in
question 4.
NOTE: a lot of the other questions in Chapters 5 and 6 look like
good midterm and/or final exam
questions to me.
