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?
We'll have to agree to disagree on that.
MC68020 is the first 32 bit
CPU in the 68K line.
How does one define 32 bit cpu? I know nothing about the
68020
but I am guessing a 32 bit bus, and some sort of virtual memory.
