64 bit OSes use special set of instructions as well as 64 bit memory space which is in principle is not supported by 32 bit processors.

Will a processor 80532 handle 64 bits?

Yes, a processor 80532 will handle and has the ability to run 64-bits. A processor 80532 is considered to be a Pentium 4 processor.

Can you make a 32 bit sys into a 128 bit sys?

Technically no. A bit is an electronic circuit therefore a processor that uses 32 bits can't be swapped out for one that uses 128 bits, because the 128 bit processor, because the other 96 circuits don't have anything to connect to. However, you can emulate a 128 bit processor with a 32 bit processor if the 32 bit processor is fast enough, or if you have a multicore processor. For example a quadcore 32 bit processor has 4 cores which handle 32 bits each, so using all 4 cores together you could process 128 bits all at once. If you run a dualcore 32bit processor using both cores you would have 64 bits and would have to run the processor twice as fast as the 128 bit processor to handle the same amount of data. A single core 32bit processor would then have to be run at 4 times the speed.

The largest number of bits the processor can process in one operation are?

It depends on the processor. An 8-bit processor can process 8-bits in a single operation while a 64-bit processor can process 64-bits at a time.

How many bits does a Nintendo DS have?

The DS's ARM9 processor is 32 bits. This is not a direct indication of its processing power, which is why it can play '64-bit' games.

How can you determine word size of a microprocessor?

Microprocessors have internal data pathways and internal registers with a fixed number of bits. An 32 bit processor will process 32 bit words, a 64 bit processor will process 64 bit words. The internal registers are sized to accommodate the word length with a single transfer. Generally, the more bits a processor can handle, the faster it can run. Smaller microprocessors might only process only 8 bits or less.Read more: What_is_word_length_of_microprocessor

What is 32bit processor and what is 64bit processor?

First off, I'm assuming you know what a microprocessor is. If not, please go look up that question (or, a related topic, the CPU (Central Processing Unit). 32 and 64 bits processors refer to the size of the native (default) word size in a processor. In a 32 bit processor, all basic operations happen on chunks of information 32-bits in size - information requiring more storage requires multiples of the 32-bit word. Likewise, 64-bit processors operate with a native size of 64-bit words. See the related question below for a more thorough explanation of the impact of 32 vs 64 bit native word size in a processor.
