As I can find the main operation is the SUBL one, between what I think is the content of the matrix, stored in ebx register and something that uses this content that is stored int edx register, but I dont know what it is... ... movl (%eax), %ebx <-- Here I store Matrix[i][j] into ebx register addl $512, %ecx leal 0(,%ebx,8), %edx <-- Here I store sth in edx... WHAT!!!?? subl %ebx, %edx movl %edx, (%eax) <-- Here I store the difference into Matrix[i][j] addl $512, %eax <-- Next position for the Matrix cmpl $65536, %ecx jne .L3 ...
