Difference Between Loosely Coupled and Tightly Coupled Multiprocessor System
In this post, we will understand the difference between loosely coupled and tightly coupled multiprocessor systems −
Loosely Coupled Multiprocessor System
In this system, every processor has its own memory module.
It is efficient when there is less interaction between tasks running on different processors.
There are no memory conflicts in general.
It is considered as a Message transfer system (MTS).
It is less expensive.
It has a low data rate.
It has distributed memory.
They are usually seen in distributed computing systems
Tightly Coupled Multiprocessor System
In this system, the processors share memory modules.
It is efficient when used with real-time processing.
It provides high speed.
It has memory conflicts.
They are connected through networks such as PMIN, IOPIN, ISIN.
It has a high data rate.
It is expensive.
It is usually seen in parallel processing systems.
