How to convert a high level language statement involving arrays into MIPS 32 bit?
Here's the high-level function: J[6] = K[d-e]
d = $t0, e = $t1, J = $s1, K = $s2, final result goes in $s4
So far I have:
lw $t2, 24($s1) #Load J[6] into $t2
sub $t3, $t0, $t1 #Subtract e from d to $t3
What I know I can't do is lw $t4, $t3($s2) but…

Is there a way to convert an integer digits into an array (i.e. 45 -> array[0] = 5 ; array [1] = 4)?
Similar to this problem: convert an integer number into an array but I don't know how this is implemented in MIPS.

Can someone help me interpret what these lines mean in MIPS?
.data 0x10000000
.align 2
Array: .word 3 6 9 12 15 18 21 24
Size: .word 8
Result: .word 0
So what does ".data" mean exactly and does "Size" correspond to the size of "Array" or is it simply another variable?
Also, what does "Result" mean? Is it an…

How do these r-type bit numbers turn into 0,11,12,18,0, and x18? (picture below)
I understand that 6,5,5,5,5,6 represent the number of bits as well, but how do they relate to the numbers 0,11,12,18,0 and x18?
