I could not clearly understand the alignment issues present in ARM. Sometimes I get BUS ERROR while running an assembly file but don't know how to resolve it. Some of the doubts:

1. Is it better to store registers pairwise or individually on the stack…

I need some indications to begin writing a program.

Write a compare routine to compare 64-bits values , using only two instructions.

Thanks for your indications !

Can someone tell me how many extra gates the 1-cycle multiply uses? If there was a 64-bit result, how many more gates would be used? Can these gates also be used to find the reciprocal of a number so instead of divides, the coder multiplies the reciprocal…
