address data
-------------------------
0xad 0x59
0xae 0xfa
0xaf 0x9d
oxb0 0xa6
0xb1 0x78
0xb2 0x04
oxb3 0xbc
oxb4 0x88
0xb8 0xff
the MIPS code:
addi $s1, $zero, 0xab
lb $t0, 5($s1)
lw $t1, 5($s1)
addi $s1, $s1, 11
lbu $t2, -8($s1)
lw $t3, -8($s1)
wat will the hexadecimal value be of registers $t0, $t1, $t2,$t3,after executing the above codes, if the system is using little-endian byte order?
You can't load word
lw $t1, 5($s1)becouse 5 isn't divisable with 4 so you also can't do this
addi $s1, $s1, 11and then
lw $t3, -8($s1)the rest is correct so $t0 is 0xFFFFFF9d and $t2 is 0x000000fa. For learning MIPS you can use SPIM (yes revers from MIPS) simulator.
