Question

Please help me answer both of those questions thank you in advance

Problem 3- Consider the following assembly code: Problem 4 Given the following code, assume x1 holds the value Ox00101000. What is the value of x2 af ter executing the folowing code 111 sub x2, x2, x1 lui 4, 12 rl 84. What are the values of megisters xt, x2. x3, and s4 afer the program ends its execution? t noier vala dad nal charge h the code abon, wite NO CNANGE Please indicale what base you are using to dsglay the values x1: x2: x4.

Answer 1

3)

Answer: Loop executes twice and is based on the value ofx2, if the value ofx2 is <0 the loop terminates. The value ofx2 at the end of the loopis-9 x1: 12 x2:-9 x3:3 x4: 14 All the values are in base 10

4)

Description:
MAIN:
bge x0,x1,NOTSET (branch to NOTSET if x0>=x1)
addi x2,x0,1 (add immediate value to x2 register i.e. x2=x0+1)
NOTSET: addi x2,x0,0 (add immediate value to x2 register i.e. x2=x0+0)
bne x2,x0,ELSE (branch to ELSE if x2≠x0)
beq x0,x0,DONE (branch to DONE if x0=x0)
ELSE: addi x2,x2,2 (add immediate value to x2 register i.e. x2=x2+2)
DONE:
What will be the value of x2 register after the execution of following code:
Assume x1=0x00101000
Case 1: if x0<x1
Suppose x0=0x0000 0000
MAIN:
bge x0,x1,NOTSET (Condition x0 >= x1 is not True)
addi x2,x0,1 (x2=x0+1 i.e. x2=0x00000001)
NOTSET: addi x2,x0,0
bne x2,x0,ELSE (go to ELSE if x2≠x0)
beq x0,x0,DONE (go to DONE if x0=x0)
ELSE: addi x2,x2,2 (x2=x2+2 i.e. x2=0x0000 0011)
DONE:
Output: if x0<x1 Then x2=x0+3
x2=0x0000 0011
Case 2: if x0>=x1
Suppose x0=0x00101001
MAIN:
bge x0,x1,NOTSET (Condition True x0>=x1, go to NOTSET)
addi x2,x0,1
NOTSET: addi x2,x0,0 (x2=x0+0 i.e. x2=x0)
bne x2,x0,ELSE (go to ELSE if x2≠x0)
beq x0,x0,DONE (go to DONE if x0=x0)
ELSE: addi x2,x2,2
DONE:
Output: if x0>=x1 Then x2=x0
x2=0x00101001
