If it's got one or more 32 bit wide ALU and 32 bit registers and a 32
bit internal data bus it's a 32 bit processor.
If a processor has 16 bit registers, 16 bit math and address
calculation, and a 16 bit address bus, but it's ALU is only 8 bit and
its internal data bus is 8 bits, it's an 8 bit processor. Right?
