Re: MICROPROCESSOR

Hmmm.... the architecture is almost tha same and Instruction sets in, I think its the Instruction Register or Instruction Que (Pipeline length) and the address bus

8086 - 16-bit microprocessor, 6 bit length in pipeline
8088 - 8-bit microprocessor, 4 bit length in pipeline

Can a 8-bit and 16-bit processors have the same instruction Set ?????!!!!! Of course 16-bit has more instructions than those on 8-bit, which means that the two processors do not have the exactly the same internal organization.

I would like to do small correction here,

8086 - 16 Bit internal registers, 16 bit Data Bus
8088 - 16 Bit internal registers, 8 bit external data bus.

Thus for all practical purposes 8088 is considered as 16 bit microprocessors, it was developed with 8 bit data bus for compatibility with 8085(8-bit microprocessor) based peripherals and systems.

Re: MICROPROCESSOR

what about clock freq. of operation.
