Branching and Looping

a. Assume for each part of this problem that the EAX register contains 00 00 00 4F and the doubleword referenced by value contains FF FF FF 38.  Determine whether each of the conditional jump statements causes a jump to dest.

#1

cmp  eax, 04fh
je dest

 

#2

add  eax, 200
js dest

 

b. This problem gives a design with an if structure and some assumptions about how the variables are stored in an assembly language program.

Give a fragment of 80×86 assembly code that implements the design. The assembly language code should flow the same as the design.

design:

if count > value

then

count: = 0;

end if;

c. This problem contains a design with a while loop. Assume that sum references a doubleword in the data segment and that count is in the ECX register. Give a fragment of 80×86 assembly code that implements the design.

sum := 0;

count : = 1;

while (sum < 1000) loop

add count to sum;

add 1 to count;

end while;
