In 8086 which of the following is not true ?
Answer: C
The statement that is not true is co-processor is interfaced in minimum mode.
The 8086 can work in minimum mode, as a single processor that generates its own bus control signals, or in maximum mode, for multiprocessor systems in which the 8288 bus controller generates them. The 8087 numeric co-processor needs the queue status and request/grant lines available only in maximum mode, so it is interfaced in maximum mode.
The other statements are true: the 8086 uses pipelining through its instruction queue, it uses segmented addressing with CS, DS, SS and ES, and it consists of an execution unit and a bus interface unit.
