COA Quiz 2

Which of the following is a correct RTL statement for subtracting the contents of register R2 from register R1?

• R1 <- R1 + R2

• R1 <- R1 - R2

• R2 <- R2 - R1

• R1 <- R2 - R1

The AND microoperation can be used for:

• Masking specific bits

• Adding binary numbers

• Incrementing the value of a register

• Shifting bits to the left

Which of the following represents an increment operation in RTL?

• R <- R - 1

• R <- R + 1

• R <- R / 2

• R <- R * 2

The XOR logical microoperation is used to:

• Set specific bits to 1

• Toggle specific bits

• Clear specific bits to 0

• Shift bits to the right

The RTL notation for a logical shift right operation on register R is:

• R <- shr R

• R <- shl R

• R <- sar R

• R <- rol R

The result of a logical shift left operation on the binary number 1101 is:

• 1010

• 1100

• 1110

• 1011

The type of microoperations that do not change the information content when moves from source to destination register is
