None of the above
|
Detailed explanation-1: -Explanation: A Coprocessor is a specially designed circuit on microprocessor chip which can perform the same task very quickly, which the microprocessor performs.
Detailed explanation-2: -Tightly coupled systems share a single memory space and share information through the shared common memory. Loosely coupled multiprocessors consist of distributed memory where each processor has its own memory and IO channels. The processors communicate with each other via message passing or interconnection switching.
Detailed explanation-3: -Maximum mode of 8086 is designed to implement 3 basic multiprocessor configurations: Co-processor (8087) Closely coupled (dedicated I/O processor: 8089) Loosely coupled (Multi-bus)
Detailed explanation-4: -High system throughput can be achieved by having more than one CPU. The system can be expanded in a modular form. A failure in one module normally does not cause a breakdown of the entire system and the faulty module can be easily detected and replaced. More items •04-Jan-2017
