Hello I am having trouble with the following problems in my

Hello, I am having trouble with the following problems in my MIPS class, can you help?

Start with the registers $t1 = 0 times 12345678 $t2 = 0 times 91abcdef $t3 = 0x000051 of $t4 = 0 times 0000bcd Show the contents of $t5 or Io and hi after each statement is executed. a. sra $t5, $t2, 5 b. sll $t5, $t1, 7 c. srl $t5, $t2, 4 d. sra $t5, $t1, 2

Solution

Answer

a.

$t2 = 0x91abcdef = (10010001101010111100110111101111)₂

Shift right 5 steps and store it in $t5, preserve the sign bit

so,

$t5 = (10000100100011010101111001101111)₂ = 0x848D5E6F

b.

$t1 = 0x12345678 = (10010001101000101011001111000)₂

Shift left 7 steps and store it in $5

so,

$t5 = (11010001010110011110000000000)₂ = 0x1A2B3C00

c.

$t2 = 0x91abcdef = (10010001101010111100110111101111)₂

Shift right 5 steps and store it in $t5

so,

$t5 = (00000100100011010101111001101111)₂ = 0x48D5E6F

d.

$t1 = 0x12345678 = (10010001101000101011001111000)₂

Shift right 2 steps and store it in $5 and preserve the sign bit

so,

$t5 = (10100100011010001010110011110)₂ = 0x148D159E
