Difference Between Loosely Coupled and Tightly Coupled Multiprocessor System

MemoryComputersHardware

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.
