Cpt S 260 Hw2 Bonus
Please print your name!
Bonus 1: Each register stores 32 bits. By inspecting the content of a
register,can I figure out whether it stores an unsigned number or a signed
number? why or why not?
Bonus 2: In MIPS,each signed number is in 32 bits. What is the largest
signed number and what is the smallest?
Bonus 3: In MIPS,the entire memory has 232 bytes and hence each
address takes 32 bits (recalling that each memory address points to a byte).
Suppose that the register $s1 stores a memory address. I want to obtain a
new memory address which is 4 plus the address stored in $s1. Then,the
new address is stored in $s2. Without considering address overflow (the new
address is out of the address range),
Can I use addiu $s2,$s1,4 to compute the new address?
Can I use addi $s2,4 to compute the new address? why or why
not?
You may want to use the following 32-bit memory address
