Deck 6: Conditional Processing Assessment

Question 1

With signed operands,the CMP instruction makes the Sign flag equal to the Overflow flag when the destination operand is less than the source operand.

Answer 1

False

Question 2

For any two integers n and m,((n XOR m)XOR m)produces n.

Answer 2

True

Question 3

The JAE instruction jumps if the (unsigned)first operand is greater than or equal to the (unsigned)second operand.

Answer 3

False

Question 4

The XOR instruction inverts each bit in a destination operand.

Question 5

The JO instruction is used after an operation involving signed integers.

Question 6

ANDing an operand with 1 sets the zero flag if the operand was originally an even number.

Question 7

The OR instruction can be used to find the intersection of two bit-mapped sets.

Question 8

The Parity flag indicates whether the lowest byte of a destination operand has an even number of 1 bits.

Question 9

XORing an operand with 1 always causes the Zero flag to be set.

Question 10

The JECXZ instruction jumps to a target label when the CX register is equal to zero.

Question 11

The TEST instruction always alters the destination operand.

Question 12

The destination operand of the OR instruction cannot be a memory operand.

Question 13

With unsigned operands,the CMP instruction sets the Carry flag when the destination operand is less than the source operand.

Question 14

The XOR instruction can be used to generate the two's complement of an integer.

Question 15

The JBE instruction is used when comparing unsigned integers.
