Constant register that stores zero value, it is used in comparison operations
$zero
$v0
$a0
$t0
$sp
Return value registers. They are used to return result from the called functions
$ra
$sp
$a0
$v0
Argument registers. They are used to pass values to callee functions
$a0,
$t0
$fp
$at
$k0
Temporary registers. They are used for intermediate operations
$fp
$k0
$at
$a0
$t0
Saved registers. They are used to store permanent data.
$s0
$t0
$a0
$fp
$at
Return address register. It stores address of next instruction(in caller) to return the execution from callee to caller.
$a0
$fp
$s0
$t0
$ra
A signle line comment in Mips using :
//

c. X= 4 ; Y= X-20; X- >$s0 , Y-> $s1
Addi $s0,$zero,4 Subi $s1, $s0,20
Addi $s0,4,$zero Subi $s1, $s0,20
Addi $s0,4,$zero Subi $s1, 20,$s1
Addi $s0,$zero,4 Subi $s1, 20,$s1
Convert the next high level code to MIPS a. X=Y+Z ; X-> $s0, Y-> $s1, Z->$t0
Addi $s0,$s0,20
