Tightly Coupled System- Shared Memory System

Shared memory multiprocessorshas has following description:

• Every processor commune through a shared global memory.
• For high speed real time processing, these method are preferable as their throughput is high as compared to loosely coupled systems.

In tightly coupled system organization, multiple processors distribute a global main memory, which may have more modules as shown in detailed Figure. The processors has also access to I/O devices. The inter- communication between memory, processors and other devices are implemented through a variety of interconnection networks, which are given below.
