How does a 32-bit OS work on a 64-bit processor? For example, if the processor has to sum up two 64-bit numbers then hew can handle that action if he only uses 32 bits?
On most architecture that support 32 and 64bit on hardware… t will be on a tie, or because what 32bit gains with smaller sizes it loses on some other potential, so it varies A LOT. but 64bit programs only dont run even worse than t do… because 64bit programs dont use 64bit as natural integer all the time… (mostly relevant on x86), otherwise the code would increase even more… also another reason is that COMPILERS stopped being enhanced for the 32bit versions of some brands (i.e. Microsoft), which is not 32bit fault… and last but not least. at least on x86 when running 32bit you also have the same MMX/SSE/AVX registers, and so the same potential, except that 64bit have more registers (with the cost of one extra byte (or two… if the constant is also 64bit), for the extra prefixes, and that along the cost of the bigger constant as well… making it less cache friendly, also the fact that the x86 architectures cleans the high bits when loading a 32bit on a 64bit, with the intent of not causing a slowdown, also cause some tricks that were doable in 32bit to use one register as two, not be able to be applied on 64bit, requiring more registers… so theres a HUGE depends on that. for ARM 64bit and 32bit are nearly equivalent, except that 64bit constants are STILL limited to just 8bit +shift, so more registers are required to hold constants than on x86, but ARM 64bit removed some of the 32bit capabilities to make space for the extra bit required for the constant/address shift, but the speed and consideration is similar on both… i.e. 64bit does not improve on anything on ARM, except ofcourse for stuff that actually require >32bit numbers, and that wont be using NEON (as neon always supported 64bit just like x86 SSE). and 64bit arm couldnt upgrade the fixed instruction size from 32bit to 64bit without causing havoc .P

For example, multiplication of two 100-digit numbers just looked at their left and right parts. This is not a real computer at all — but a mathematical problem. If a number of overflows, no one cares. If a number is less than the 32 bits — no one cares — you might as well use the overflow for something else. What is interesting is that computers that can do all this — and more — are out of scope for this post. But you will learn more about it in your courses. Nowadays, there are a number of architectures that do everything mentioned from step 1 above. We are currently talking about the AMD Operon. A high‑performance processor with many cores. But that's only one example. The Leon chip is a general purpose processor that allows you to add, multiply, and divide any number of cores. This is the.
