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, Valuc_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. 1. Instruction 5 represents a Conditional Jump operation. Jump will be performed if carry flag is set.

1. 2. Instruction 8 represents Unconditional Jump operation.

1. 3. Computation performed by Instruction 4 to create conditional test criteria in the flags: Value_B - Value_A i.e., Value_B minus Value_A

1.4 Conditional jump will be taken when CF=1. JC makes the conditional jump when carry flag is set to 1.

1.5 If carry flag is set, Then Path: I9, I10, I11

1.5 If carry flag is not set, Else Path: I6, I7, I8, I11

1.6 Result is produced in Register CX. Result is a word-wide number.
