Question

In a tightly coupled system, when a processor is using the bus then the local bus of other processors is in

(a) hold state

(b) high impedance state

(c) halt state

(d) low impedance state

I have been asked this question in a dream while sleeping

I need to ask this question from Tightly Coupled and Loosely Coupled Systems topic in division Multimicroprocessor Systems of Microprocessor

Answer 1

Right option is (b) high impedance state

To explain: When a processor is using the bus then the other processors maintain their local buses in high impedance state.
