(b) both processors must know the address map

(c) loss of effective local memory space

(d) all of the mentioned

This question was addressed to me in an international level competition.

My doubt is from Interconnection Topologies topic in division Multimicroprocessor Systems of Microprocessor

Answer 1

The correct choice is (d) all of the mentioned

Easy explanation: The disadvantage of bus window technique is that both processors must know implicitly about the existence of a bus window, its size and the address map. It also results in loss of effective local memory space.
