Please try to answer all. I have no idea on MIPS.

MIPS ASSEMBLY

10. Which of the following can be used to place 5 in $8?

a. li $8, 5

b. addi $8, $0, 5

c. ori $8, $0, 5

d. all

11. MIPS assembly include instructions addi and subi. But, subi is a pseudocode- that is, there is no native MIPS machine code for subi. Which of the following MIPS ISA code is equivalent to subi $8, $8, 5?

a. sub $8, $8, $5

b. addi $8, $8, -5

c. add $8, $8, -5

d. ori $8, $8, -5

12. MIPS assembly include a pseudocode move to copy the contents of a register to another register; for example, move rd, rs will copy the contents of rs to rd ( i.e. R[rd] R[rs] ). Which of the following MIPS machine code (ISA code) can be used in place of the pseudocode move $8, $9 ?

a. addu $8, $0, $9

b. add $8, $0, $9

c. addi $8, $9, 0

d. all of the above

13. Consider the following JAVA code. Suppose x is in $t0 and y is in $t1, which of the following MIPS ISA code sequence will be equivalent to the above JAVA code?

a. ori $t0, $0, 5 add $t1, $t0, $t0

b. add $t0, $5, 0 addi $t0, $t1, $t1

c. int x, 5, 0 mul y, 2 , x

d. add $t0, $t0, 5 add $t1, $t1, 0

14. Consider the following MIPS ISA code. What will be in $8 after the last they both are executed in the given order?

a. 8

b. 16

c. 2

d. 4
