Question
Answer the questions that follow about the structure and operation of the program that follows. Does instruction 5 represent a conditional or unconditional jump operation? Ans: _________ Does instruction 8 represent a conditional or unconditional jump operation? Ans: _________ Write a numeric expression in terms of symbols Value_A, Value_B, and/or Value_C that represents the computation that instruction 4 performs to create the conditional test criteria in the flags. Ans: _________ What is the "criteria" that will make the conditional jump to be "taken" (express the answer in terms of a state (0 or 1) of a specific flag (CF, ZF, SF, PF, etc.)-ie. ?F=? Ans: _________ Which instruction(s) represent the "Then path." (Just list the I numbers: 12, 12, etc.) Ans: _________ Which instruction(s) represent the "Else path." (Just list the I numbers: II. 12, etc.) Ans: _________ In which register is the result produced? Is this result a byte-wide, or word-wide number? Ans: _________.Explanation / Answer
1 ans:
JMP is used to represent Conditional or unconditional jump in assembly language
See the syntax JMP L3;
In the given snippet JC False
JC means Jump if carry.
2 ans: JMP Next is given statement in the above code
it is represent conditional jump in the above code.
3 Ans:
In the above code instruction 6 and 9 are the computation of values A,B and C.
Add AX, BX (addition of Ax annd Bx)
SUb AX , BX (Subtraction of Ax and BX)
4 ans: For this
whne the CMP AX BX is false then it jumps to next here using CF flag
CMP BX AX
JC False CF = 1
ADD AX BX
if the flag state is 0
CMP BX AX
JC False CF = 0
SUB AX BX
5ans:
Instruction 4 represents the Then path
6 ans:
Instruction 5 represents the Else path
7Ans :
CX is the register to produe the value in number.
