32-bit means that a microprocessor can execute 4 bytes of data in one instruction cycle while 64-bit means that a microprocessor can execute 8 bytes of data in one instruction cycle. Since microprocessor needs to talk to other parts of computer to get and send data i.e. memory, data bus and video controller etc.
While a 16-bit processor can simulate 32-bit arithmetic using double-precision operands, 32-bit processors are much more efficient. While 16-bit processors can use segment registers to access more than 64K elements of memory, this technique becomes awkward and slow if it must be used frequently.
The Cortex-M3 processor is a 32-bit processor, with a 32-bit wide data path, register bank and memory interface. There are 13 general-purpose registers, two stack pointers, a link register, a program counter and a number of special registers including a program status register.
