 |
|
The 4004 was a bit-slice-processor meaning that it was a microprocessor divided among several chips.
The first microprocssor might have been the 8008 where all microprocessing functions were on one chip and all address and data lines came out to the pins on that one chip.
That does not diminish the collectability of the 4004, maybe it just alters it's microprocessing position a bit. |

I think you're mixing 4004 processor with 3002 (or other) bit slice processor.

Chip-set probably a better word to describe the 4004 & other support chips to make up the complete CPU

and a modern CPU is still not the only chip on a board. They all need help, noone can work alone, lol

What is the definition of a microprocessor?
For my own rule of thumb it is if there are a arithmetic logic
unit and a control unit on one chip-die, the 4004 has both.
Moreover accus, registers, instruction decoder, program counter...
so really a microprocessor I would say!
